TITLE 10--ENERGY
CHAPTER II--DEPARTMENT OF ENERGY
PART 431_ENERGY EFFICIENCY PROGRAM FOR CERTAIN COMMERCIAL AND INDUSTRIAL
EQUIPMENT--Table of Contents
Subpart B_Electric Motors
Sec. 431.36 Compliance Certification.
(a) General. Beginning April 26, 2003, a manufacturer or private
labeler shall not distribute in commerce any basic model of an electric
motor which is subject to an energy efficiency standard set forth in
this subpart unless it has submitted to the Department a Compliance
Certification certifying, in accordance with the provisions of this
section, that the basic model meets the requirements of the applicable
standard. The representations in the Compliance Certification must be
based upon the basic model's energy efficiency as determined in
accordance with the applicable requirements of this subpart. This means,
in part, that either:
(1) The representations as to the basic model must be based on use
of a certification organization; or
(2) Any testing of the basic model on which the representations are
based must be conducted at an accredited laboratory.
(b) Required contents--(1) General representations. Each Compliance
Certification must certify that:
(i) The nominal full load efficiency for each basic model of
electric motor distributed is not less than the minimum nominal full
load efficiency required for that motor by Sec. 431.25;
(ii) All required determinations on which the Compliance
Certification is based were made in compliance with the applicable
requirements prescribed in this subpart;
(iii) All information reported in the Compliance Certification is
true, accurate, and complete; and
[[Page 314]]
(iv) The manufacturer or private labeler is aware of the penalties
associated with violations of the Act and the regulations thereunder,
and of 18 U.S.C. 1001 which prohibits knowingly making false statements
to the Federal Government.
(2) Specific data. (i) For each rating of electric motor (as the
term ``rating'' is defined in the definition of basic model) which a
manufacturer or private labeler distributes, the Compliance
Certification must report the nominal full load efficiency, determined
pursuant to Sec. Sec. 431.16 and 431.17, of the least efficient basic
model within that rating.
(ii) The Compliance Certification must identify the basic models on
which actual testing has been performed to meet the requirements of
Sec. 431.17.
(iii) The format for a Compliance Certification is set forth in
appendix C of this subpart.
(c) Optional contents. In any Compliance Certification, a
manufacturer or private labeler may at its option request that DOE
provide it with a unique Compliance Certification number (``CC number'')
for any brand name, trademark or other label name under which the
manufacturer or private labeler distributes electric motors covered by
the Certification. Such a Compliance Certification must also identify
all other names, if any, under which the manufacturer or private labeler
distributes electric motors, and to which the request does not apply.
(d) Signature and submission. A manufacturer or private labeler must
submit the Compliance Certification either on its own behalf, signed by
a corporate officer of the company, or through a third party (for
example, a trade association or other authorized representative) acting
on its behalf. Where a third party is used, the Compliance Certification
must identify the official of the manufacturer or private labeler who
authorized the third party to make representations on the company's
behalf, and must be signed by a corporate official of the third party.
The Compliance Certification must be submitted to the Department by
certified mail, to Department of Energy, Assistant Secretary for Energy
Efficiency and Renewable Energy, Building Technologies (EE-2J),
Forrestal Building, 1000 Independence Avenue, SW., Washington, DC 20585-
0121.
(e) New basic models. For electric motors, a Compliance
Certification must be submitted for a new basic model only if the
manufacturer or private labeler has not previously submitted to DOE a
Compliance Certification, that meets the requirements of this section,
for a basic model that has the same rating as the new basic model, and
that has a lower nominal full load efficiency than the new basic model.
(f) Response to Compliance Certification; Compliance Certification
Number (CC number)--(1) DOE processing of Certification. Promptly upon
receipt of a Compliance Certification, the Department will determine
whether the document contains all of the elements required by this
section, and may, in its discretion, determine whether all or part of
the information provided in the document is accurate. The Department
will then advise the submitting party in writing either that the
Compliance Certification does not satisfy the requirements of this
section, in which case the document will be returned, or that the
Compliance Certification satisfies this section. The Department will
also advise the submitting party of the basis for its determination.
(2) Issuance of CC number(s). (i) Initial Compliance Certification.
When DOE advises that the initial Compliance Certification submitted by
or on behalf of a manufacturer or private labeler is acceptable, either:
(A) DOE will provide a single unique CC number, ``CC--,'' to the
manufacturer or private labeler, and such CC number shall be applicable
to all electric motors distributed by the manufacturer or private
labeler, or
(B) When required by paragraph (f)(3) of this section, DOE will
provide more than one CC number to the manufacturer or private labeler.
(ii) Subsequent Compliance Certification. When DOE advises that any
other Compliance Certification is acceptable, it will provide a unique
CC number for any brand name, trademark or other name when required by
paragraph (f)(3) of this section.
[[Page 315]]
(iii) When DOE declines to provide a CC number as requested by a
manufacturer or private labeler in accordance with Sec. 431.36(c), DOE
will advise the requester of the reasons for such refusal.
(3) Issuance of two or more CC numbers. (i) DOE will provide a
unique CC number for each brand name, trademark or other label name for
which a manufacturer or private labeler requests such a number in
accordance with Sec. 431.36(c), except as follows. DOE will not provide
a CC number for any brand name, trademark or other label name
(A) For which DOE has previously provided a CC number, or
(B) That duplicates or overlaps with other names under which the
manufacturer or private labeler sells electric motors.
(ii) Once DOE has provided a CC number for a particular name, that
shall be the only CC number applicable to all electric motors
distributed by the manufacturer or private labeler under that name.
(iii) If the Compliance Certification in which a manufacturer or
private labeler requests a CC number is the initial Compliance
Certification submitted by it or on its behalf, and it distributes
electric motors not covered by the CC number(s) DOE provides in response
to the request(s), DOE will also provide a unique CC number that shall
be applicable to all of these other motors.
Appendix A to Subpart B of 10 CFR Part 431, Policy Statement for
Electric Motors Covered Under the Energy Policy and Conservation Act
This is a reprint of a policy statement which was published on
November 5, 1997 at 62 FR 59978.
Policy Statement for Electric Motors Covered Under the Energy Policy and
Conservation Act
I. Introduction
The Energy Policy and Conservation Act (EPCA), 42 U.S.C. 6311, et
seq., establishes energy efficiency standards and test procedures for
certain commercial and industrial electric motors manufactured (alone or
as a component of another piece of equipment) after October 24, 1997,
or, in the case of an electric motor which requires listing or
certification by a nationally recognized safety testing laboratory,
after October 24, 1999.\1\ EPCA also directs the Department of Energy
(DOE or Department) to implement the statutory test procedures
prescribed for motors, and to require efficiency labeling of motors and
certification that covered motors comply with the standards.
---------------------------------------------------------------------------
\1\ The term ``manufacture'' means ``to manufacture, produce,
assemble or import.'' EPCA Sec. 321(10). Thus, the standards apply to
motors produced, assembled, imported or manufactured after these
statutory deadlines.
---------------------------------------------------------------------------
Section 340(13)(A) of EPCA defines the term ``electric motor'' based
essentially on the construction and rating system in the National
Electrical Manufacturers Association (NEMA) Standards Publication MG1.
Sections 340(13)(B) and (c) of EPCA define the terms ``definite purpose
motor'' and ``special purpose motor,'' respectively, for which the
statute prescribes no efficiency standards.
In its proposed rule to implement the EPCA provisions that apply to
motors (61 FR 60440, November 27, 1996), DOE has proposed to clarify the
statutory definition of ``electric motor,'' to mean a machine which
converts electrical power into rotational mechanical power and which:
(1) Is a general purpose motor, including motors with explosion-proof
construction \2\; (2) is a single speed, induction motor; (3) is rated
for continuous duty operation, or is rated duty type S-1 (IEC) \3\; (4)
contains a squirrel-cage or cage (IEC) rotor; (5) has foot-mounting,
including foot-mounting with flanges or detachable feet; (6) is built in
accordance with NEMA T-frame dimensions, or IEC metric equivalents
(IEC); (7) has performance in accordance with NEMA Design A or B
characteristics, or equivalent designs such as IEC Design N (IEC); and
(8) operates on polyphase alternating current 60-Hertz sinusoidal power,
and is (i) rated 230 volts or 460 volts, or both, including any motor
that is rated at multi-voltages that include 230 volts or 460
[[Page 316]]
volts, or (ii) can be operated on 230 volts or 460 volts, or both.
---------------------------------------------------------------------------
\2\ Section 342(b)(1) of EPCA recognizes that EPCA's efficiency
standards cover ``motors which require listing or certification by a
nationally recognized safety testing laboratory.'' This applies, for
example, to explosion-proof motors which are otherwise general purpose
motors.
\3\ Terms followed by the parenthetical ``IEC'' are referred to in
the International Electrotechnical Commission (IEC) Standard 34-1. Such
terms are included in DOE's proposed definition of ``electric motor''
because DOE believes EPCA's efficiency requirements apply to metric
system motors that conform to IEC Standard 34, and that are identical or
equivalent to motors constructed in accordance with NEMA MG1 and covered
by the statute.
---------------------------------------------------------------------------
Notwithstanding the clarification provided in the proposed rule,
there still appears to be uncertainty as to which motors EPCA covers. It
is widely understood that the statute covers ``general purpose'' motors
that are manufactured for a variety of applications, and that meet
EPCA's definition of ``electric motor.'' Many modifications, however,
can be made to such generic motors. Motor manufacturers have expressed
concern as to precisely which motors with such modifications are covered
under the statute, and as to whether manufacturers will be able to
comply with the statute by October 25, 1997 with respect to all of these
covered motors. Consequently, motor manufacturers have requested that
the Department provide additional guidance as to which types of motors
are ``electric motors,'' ``definite purpose motors,'' and ``special
purpose motors'' under EPCA. The policy statement that follows is based
upon input from motor manufacturers and energy efficiency advocates, and
provides such guidance.
II. Guidelines for Determining Whether a Motor Is Covered by EPCA
A. General
EPCA specifies minimum nominal full-load energy efficiency standards
for 1 to 200 horsepower electric motors, and, to measure compliance with
those standards, prescribes use of the test procedures in NEMA Standard
MG1 and Institute of Electrical and Electronics Engineers, Inc., (IEEE)
Standard 112. In DOE's view, as stated in Assistant Secretary Ervin's
letter of May 9, 1996, to NEMA's Malcolm O'Hagan, until DOE's
regulations become effective, manufacturers can establish compliance
with these EPCA requirements through use of competent and reliable
procedures or methods that give reasonable assurance of such compliance.
So long as these criteria are met, manufacturers may conduct required
testing in their own laboratories or in independent laboratories, and
may employ alternative correlation methods (in lieu of actual testing)
for some motors. Manufacturers may also establish their compliance with
EPCA standards and test procedures through use of third party
certification or verification programs such as those recognized by
Natural Resources Canada. Labeling and certification requirements will
become effective only after DOE has promulgated a final rule prescribing
such requirements.
Motors with features or characteristics that do not meet the
statutory definition of ``electric motor'' are not covered, and
therefore are not required to meet EPCA requirements. Examples include
motors without feet and without provisions for feet, and variable speed
motors operated on a variable frequency power supply. Similarly, multi
speed motors and variable speed motors, such as inverter duty motors,
are not covered equipment, based on their intrinsic design for use at
variable speeds. However, NEMA Design A or B motors that are single
speed, meet all other criteria under the definitions in EPCA for covered
equipment, and can be used with an inverter in variable speed
applications as an additional feature, are covered equipment under EPCA.
In other words, being suitable for use on an inverter by itself does not
exempt a motor from EPCA requirements.
Section 340(13)(F) of EPCA, defines a ``small electric motor'' as
``a NEMA general purpose alternating current single-speed induction
motor, built in a two-digit frame number series in accordance with NEMA
Standards Publication MG 1-1987.'' Section 346 of EPCA requires DOE to
prescribe testing requirements and efficiency standards only for those
small electric motors for which the Secretary determines that standards
are warranted. The Department has not yet made such a determination.
B. Electrical Features
As noted above, the Department's proposed definition of ``electric
motor'' provides in part that it is a motor that ``operates on polyphase
alternating current 60-Hertz sinusoidal power, and * * * can be operated
on 230 volts or 460 volts, or both.'' In DOE's view, ``can be operated''
implicitly means that the motor can be operated successfully. According
to NEMA Standards Publication MG1-1993, paragraph 12.44, ``Variations
from Rated Voltage and Rated Frequency,'' alternating-current motors
must operate successfully under running conditions at rated load with a
variation in the voltage or the frequency up to the following: Plus or
minus 10 percent of rated voltage, with rated frequency for induction
motors; \4\ plus or minus 5 percent of rated frequency, with rated
voltage; and a combined variation in voltage and frequency of 10 percent
(sum of absolute values) of the rated values, provided the frequency
variation does not exceed plus or minus 5 percent of rated frequency.
DOE believes that, for purposes of determining whether a motor meets
EPCA's definition of ``electric motor,'' these criteria should be used
to determine when a motor that is not rated at 230 or 460 volts or 60
Hertz can be operated at such voltage and frequency.\5\
---------------------------------------------------------------------------
\4\ For example, a motor that is rated at 220 volts should operate
successfully on 230 volts, since 220 + .10(220) = 242 volts. A 208 volt
motor, however, would not be expected to operate successfully on 230
volts, since 208 + .10(208) = 228.8 volts.
\5\ The Department understands that a motor that can operate at such
voltage and frequency, based on variations defined for successful
operation, will not necessarily perform in accordance with the industry
standards established for operation at the motor's rated voltage and
frequency. In addition, under the test procedures prescribed by EPCA,
motors are to be tested at their rated values. Therefore, in DOE's view
a motor that is not rated for 230 or 460 volts, or 60 Hertz, but that
can be successfully operated at these levels, must meet the energy
efficiency requirements at its rated voltage(s) and frequency. DOE also
notes that when a motor is rated to include a wider voltage range that
includes 230/460 volts, the motor should meet the energy efficiency
requirements at 230 volts or 460 volts.
---------------------------------------------------------------------------
[[Page 317]]
NEMA Standards Publication MG1 categorizes electrical modifications
to motors according to performance characteristics that include locked
rotor torque, breakdown torque, pull-up torque, locked rotor current,
and slip at rated load, and assigns design letters, such as Design A, B,
C, D, or E, to identify various combinations of such electrical
performance characteristics. Under Section 340(13)(A) of EPCA, electric
motors subject to EPCA efficiency requirements include only motors that
fall within NEMA ``Design A and B * * * as defined in [NEMA] Standards
Publication MG1-1987.'' As to locked rotor torque, for example, MG1
specifies a minimum performance value for a Design A or B motor of a
given speed and horsepower, and somewhat higher minimum values for
Design C and D motors of the same speed and horsepower. The Department
understands that, under MG1, the industry classifies a motor as Design A
or B if it has a locked rotor torque at or above the minimum for A and B
but below the minimum for Design C, so long as it otherwise meets the
criteria for Design A or B. Therefore, in the Department's view, such a
motor is covered by EPCA's requirements for electric motors. By contrast
a motor that meets or exceeds the minimum locked rotor torque for Design
C or D is not covered by EPCA. In sum, if a motor has electrical
modifications that meet Design A or B performance requirements it is
covered by EPCA, and if its characteristics meet Design C, D or E it is
not covered.
C. Size
Motors designed for use on a particular type of application which
are in a frame size that is one or more frame series larger than the
frame size assigned to that rating by sections 1.2 and 1.3 of NEMA
Standards Publication MG 13-1984 (R1990), ``Frame Assignments for
Alternating Current Integral-Horsepower Induction Motors,'' are not, in
the Department's view, usable in most general purpose applications. This
is due to the physical size increase associated with a frame series
change. A frame series is defined as the first two digits of the frame
size designation. For example, 324T and 326T are both in the same frame
series, while 364T is in the next larger frame series. Hence, in the
Department's view, a motor that is of a larger frame series than
normally assigned to that standard rating of motor is not covered by
EPCA. A physically larger motor within the same frame series would be
covered, however, because it would be usable in most general purpose
applications.
Motors built in a T-frame series or a T-frame size smaller than that
assigned by MG 13-1984 (R1990) are also considered usable in most
general purpose applications. This is because simple modifications can
generally be made to fit a smaller motor in place of a motor with a
larger frame size assigned in conformity with NEMA MG 13. Therefore, DOE
believes that such smaller motors are covered by EPCA.
D. Motors With Seals
Some electric motors have seals to prevent ingress of water, dust,
oil, and other foreign materials into the motor. DOE understands that,
typically, a manufacturer will add seals to a motor that it
manufactures, so that it will sell two motors that are identical except
that one has seals and the other does not. In such a situation, if the
motor without seals is ``general purpose'' and covered by EPCA's
efficiency requirements, then the motor with seals will also be covered
because it can still be used in most general purpose applications. DOE
understands, however, that manufacturers previously believed motors with
seals were not covered under EPCA, in part because IEEE Standard 112,
``Test Procedure for Polyphase Induction Motors and Generators,''
prescribed by EPCA, does not address how to test a motor with seals
installed.
The efficiency rating of such a motor, if determined with seals
installed and when the motor is new, apparently would significantly
understate the efficiency of the motor as operated. New seals are stiff,
and provide friction that is absent after their initial break-in period.
DOE understands that, after this initial period, the efficiency ratings
determined for the same motor with and without seals would be virtually
identical. To construe EPCA, therefore, as requiring such separate
efficiency determinations would impose an unnecessary burden on
manufacturers.
In light of the foregoing, the Department believes that EPCA
generally permits the efficiency of a motor with seals to be determined
without the seals installed. Furthermore, notwithstanding the prior
belief that such motors are not covered by EPCA, use of this approach to
determining efficiency will enable manufacturers to meet EPCA's
standards with respect to covered motors with
[[Page 318]]
seals by the date the standards go into effect on October 25, 1997.
III. Discussion of How DOE Would Apply EPCA Definitions, Using the
Foregoing Guidelines
Using the foregoing guidelines, the attached matrix provides DOE's
view as to which motors with common features are covered by EPCA.
Because manufacturers produce many basic models that have many
modifications of generic general purpose motors, the Department does not
represent that the matrix is all-inclusive. Rather it is a set of
examples demonstrating how DOE would apply EPCA definitions, as
construed by the above guidelines, to various motor types. By extension
of these examples, most motors currently in production, or to be
designed in the future, could probably be classified. The matrix
classifies motors into five categories, which are discussed in the
following passages.
Category I--For ``electric motors'' (manufactured alone or as a
component of another piece of equipment) in Category I, DOE will enforce
EPCA efficiency standards and test procedures beginning on October 25,
1997.
The Department understands that some motors essentially are
relatively simple modifications of generic general purpose motors.
Modifications could consist, for example, of minor changes such as the
addition of temperature sensors or a heater, the addition of a shaft
extension and a brake disk from a kit, or changes in exterior features
such as the motor housing. Such motors can still be used for most
general purpose applications, and the modifications have little or no
effect on motor performance. Nor do the modifications affect energy
efficiency.
Category II--For certain motors that are ``definite purpose''
according to present industry practice, but that can be used in most
general purpose applications, DOE will generally enforce EPCA efficiency
standards and test procedures beginning no later than October 25, 1999.
General Statement
EPCA does not prescribe standards and test procedures for ``definite
purpose motors.'' Section 340(13)(B) of EPCA defines the term ``definite
purpose motor'' as ``any motor designed in standard ratings with
standard operating characteristics or standard mechanical construction
for use under service conditions other than usual or for use on a
particular type of application and which cannot be used in most general
purpose applications.'' [Emphasis added.] Except, significantly, for
exclusion of the italicized language, the industry definition of
``definite purpose motor,'' set forth in NEMA MG1, is identical to the
foregoing.
Category II consists of electric motors with horsepower ratings that
fall between the horsepower ratings in Section 342(b)(1) of EPCA,
thermally protected motors, and motors with roller bearings. As with
motors in Category I, these motors are essentially modifications of
generic general purpose motors. Generally, however, the modifications
contained in these motors are more extensive and complex than the
modifications in Category I motors. These Category II motors have been
considered ``definite purpose'' in common industry parlance, but are
covered equipment under EPCA because they can be used in most general
purpose applications.
According to statements provided during the January 15, 1997, Public
Hearing, Tr. pgs. 238-239, Category II motors were, until recently,
viewed by most manufacturers as definite purpose motors, consistent with
the industry definition that did not contain the clause ``which cannot
be used in most general purpose applications.'' Hence, DOE understands
that many manufacturers assumed these motors were not subject to EPCA's
efficiency standards. During the period prior and subsequent to the
hearing, discussions among manufacturers resulted in a new understanding
that such motors are general purpose under EPCA, since they can be used
in most general purpose applications. Thus, the industry only recently
recognized that such motors are covered under EPCA. Although the
statutory definition adopted in 1992 contained the above-quoted
definition of ``definite purpose,'' the delay in issuing regulations
which embody this definition may have contributed to industry's delay in
recognizing that these motors are covered.
The Department understands that redesign and testing these motors in
order to meet the efficiency standards in the statute may require a
substantial amount of time. Given the recent recognition that they are
covered, it is not realistic to expect these motors will be able to
comply by October 25, 1997. A substantial period beyond that will be
required. Moreover, the Department believes different manufacturers will
need to take different approaches to achieving compliance with respect
to these motors, and that, for a particular type of motor, some
manufacturers will be able to comply sooner than others. Thus, the
Department intends to refrain from taking enforcement action for two
years, until October 25, 1999, with respect to motors with horsepower
ratings that fall between the horsepower ratings in Section 342(b)(1) of
EPCA, thermally protected motors, and motors with roller bearings.
Manufacturers are encouraged, however, to manufacture these motors in
compliance with EPCA at the earliest possible date.
The following sets forth in greater detail, for each of these types
of motors, the basis for the Department's policy to refrain from
enforcement for two years. Also set forth is
[[Page 319]]
additional explanation of the Department's understanding as to why
manufacturers previously believed intermediate horsepower motors were
not covered by EPCA.
Intermediate Horsepower Ratings
Section 342(b)(1) of EPCA specifies efficiency standards for
electric motors with 19 specific horsepower ratings, ranging from one
through 200 horsepower. Each is a preferred or standardized horsepower
rating as reflected in the table in NEMA Standards Publication MG1-1993,
paragraph 10.32.4, Polyphase Medium Induction Motors. However, an
``electric motor,'' as defined by EPCA, can be built at other horsepower
ratings, such as 6 horsepower, 65 horsepower, or 175 horsepower. Such
motors, rated at horsepower levels between any two adjacent horsepower
ratings identified in Section 342(b)(1) of EPCA will be referred to as
``intermediate horsepower motors.'' In the Department's view, efficiency
standards apply to every motor that has a rating from one through 200
horsepower (or kilowatt equivalents), and that otherwise meets the
criteria for an ``electric motor'' under EPCA, including an electric
motor with an intermediate horsepower (or kW) rating.
To date, these motors have typically been designed in conjunction
with and supplied to a specific customer to fulfill certain performance
and design requirements of a particular application, as for example to
run a certain type of equipment. See the discussion in Section IV below
on ``original equipment'' and ``original equipment manufacturers.'' In
large part for these reasons, manufacturers believed intermediate
horsepower motors to be ``definite purpose motors'' that were not
covered by EPCA. Despite their specific uses, however, these motors are
electric motors under EPCA when they are capable of being used in most
general purpose applications.
Features of a motor that are directly related to its horsepower
rating include its physical size, and the ratings of its controller and
protective devices. These aspects of a 175 horsepower motor, for
example, which is an intermediate horsepower motor, must be appropriate
to that horsepower, and would generally differ from the same aspects of
150 and 200 horsepower motors, the two standard horsepower ratings
closest to 175. To re-design an existing intermediate horsepower
electric motor so that it complies with EPCA could involve all of these
elements of a motor's design. For example, the addition of material
necessary to achieve EPCA's prescribed level of efficiency could cause
the size of the motor to increase. The addition of magnetic material
would invite higher inrush current that could cause an incorrectly sized
motor controller to malfunction, or the circuit breaker with a standard
rating to trip unnecessarily, or both. The Department believes motor
manufacturers will require a substantial amount of time to redesign and
retest each intermediate horsepower electric motor they manufacture.
To the extent such intermediate horsepower electric motors become
unavailable because motor manufacturers have recognized only recently
that they are covered by EPCA, equipment in which they are incorporated
would temporarily become unavailable also. Moreover, re-design of such a
motor to comply with EPCA could cause changes in the motor that require
re-design of the equipment in which the motor is used. For example, if
an intermediate horsepower electric motor becomes larger, it might no
longer fit in the equipment for which it was designed. In such
instances, the equipment would have to be re-designed. Because these
motors were previously thought not to be covered, equipment
manufacturers may not have had sufficient lead time to make the
necessary changes to the equipment without interrupting its production.
With respect to intermediate horsepower motors, the Department
intends to refrain from enforcing EPCA for a period of 24 months only as
to such motor designs that were being manufactured prior to the date
this Policy Statement was issued. The Department is concerned that small
adjustments could be made to the horsepower rating of an existing
electric motor, in an effort to delay compliance with EPCA, if it
delayed enforcement as to all intermediate horsepower motors produced
during the 24 month period. For example, a 50 horsepower motor that has
a service factor of 1.15 could be renameplated as a 57\1/2\ horsepower
motor that has a 1.0 service factor. By making this delay in enforcement
applicable only to pre-existing designs of intermediate horsepower
motors, the Department believes it has made adequate provision for the
manufacture of bona fide intermediate horsepower motor designs that
cannot be changed to be in compliance with EPCA by October 25, 1997.
Thermally Protected Motors
The Department understands that in order to redesign a thermally
protected motor to improve its efficiency so that it complies with EPCA,
various changes in the windings must be made which will require the
thermal protector to be re-selected. Such devices sense the inrush and
running current of the motor, as well as the operating temperature. Any
changes to a motor that affect these characteristics will prevent the
protector from operating correctly. When a new protector is selected,
the motor must be tested to verify proper operation of the device in the
motor. The motor manufacturer would test the locked rotor and overload
conditions, which could take several days, and the
[[Page 320]]
results may dictate that a second selection is needed with additional
testing. When the manufacturer has finished testing, typically the
manufacturer will have a third party conduct additional testing. This
testing may include cycling the motor in a locked-rotor condition to
verify that the protector functions properly. This testing may take days
or even weeks to perform for a particular model of motor.
Since it was only recently recognized by industry that these motors
are covered by EPCA, in the Department's view the total testing program
makes it impossible for manufacturers to comply with the EPCA efficiency
levels in thermally protected motors by October 25, 1997, especially
since each different motor winding must be tested and motor winding/
thermal protector combinations number in the thousands.
Motors With Roller Bearings
Motors with roller bearings fit within the definition of electric
motor under the statute. However, because the IEEE Standard 112 Test
Method B does not provide measures to test motors with roller bearings
installed, manufacturers mistakenly believed such motors were not
covered. Under IEEE Standard 112, a motor with roller bearings could
only be tested for efficiency with the roller bearings removed and
standard ball bearings installed as temporary substitutes. Then on the
basis of the energy efficiency information gained from that test, the
manufacturer may need to redesign the motor in order to comply with the
statute. In this situation, the Department understands that testing,
redesigning, and retesting lines of motors with roller bearings, to
establish compliance, would be difficult and time consuming.
Categories III, IV and V--Motors not within EPCA's definition of
``electric motor,'' and not covered by EPCA.
Close-Coupled Pump Motors
NEMA Standards Publication MG1-1993, with revisions one through
three, Part 18, ``Definite-Purpose Machines,'' defines ``a face-mounting
close-coupled pump motor'' as ``a medium alternating-current squirrel-
cage induction open or totally enclosed motor, with or without feet,
having a shaft suitable for mounting an impeller and sealing device.''
Paragraphs MG1-18.601-18.614 specify its performance, face and shaft
mounting dimensions, and frame assignments that replace the suffix
letters T and TS with the suffix letters JM and JP.
The Department understands that such motors are designed in standard
ratings with standard operating characteristics for use in certain
close-coupled pumps and pumping applications, but cannot be used in non-
pumping applications, such as, for example, conveyors. Consequently, the
Department believes close-coupled pump motors are definite-purpose
motors not covered by EPCA. However, a motor that meets EPCA's
definition of ``electric motor,'' and which can be coupled to a pump,
for example by means of a C-face or D-flange end shield, as depicted in
NEMA Standards Publication MG1, Part 4, ``Dimensions, Tolerances, and
Mounting,'' is covered.
Totally-Enclosed Non-Ventilated (TENV) and Totally-Enclosed Air-Over
(TEAO) Motors
A motor designated in NEMA MG1-1993, paragraph MG1-1.26.1, as
``totally-enclosed non-ventilated (IP54, IC410)'' \6\ is ``not equipped
for cooling by means external to the enclosing parts.'' This means that
the motor, when properly applied, does not require the use of any
additional means of cooling installed external to the motor enclosure.
The TENV motor is cooled by natural conduction and natural convection of
the motor heat into the surrounding environment. As stated in NEMA MG1-
1993, Suggested Standard for Future Design, paragraph MG1-1.26.1a, a
TENV motor ``is only equipped for cooling by free convection.'' The
general requirement for the installation of the TENV motor is that it
not be placed in a restricted space that would inhibit this natural
dissipation of the motor heat. Most general purpose applications use
motors which include a means for forcing air flow through or around the
motor and usually through the enclosed space and, therefore, can be used
in spaces that are more restrictive than those required for TENV motors.
Placing a TENV motor in such common restricted areas is likely to cause
the motor to overheat. The TENV motor may also be larger than the motors
used in most general purpose applications, and would take up more of the
available space, thus reducing the size of the open area surrounding the
motor. Installation of a TENV motor might require, therefore, an
additional means of ventilation to continually exchange the ambient
around the motor.
---------------------------------------------------------------------------
\6\ IP refers to the IEC Standard 34-5: Classification of degrees of
protection provided by enclosures for rotating machines. IC refers to
the IEC Standard 34-6: Methods of cooling rotating machinery. The IP and
IC codes are referenced in the NEMA designations for TENV and TEAO
motors in MG1-1993 Part 1, ``Classification According to Environmental
Protection and Methods of Cooling,'' as a Suggested Standard for Future
Design, since the TENV and TEAO motors conform to IEC Standards. Details
of protection (IP) and methods of cooling (IC) are defined in MG1 Part 5
and Part 6, respectively.
---------------------------------------------------------------------------
A motor designated in NEMA MG1-1993 as ``totally-enclosed air-over
(IP54, IC417)'' is
[[Page 321]]
intended to be cooled by ventilation means external to (i.e., separate
and independent from) the motor, such as a fan. The motor must be
provided with the additional ventilation to prevent it from overheating.
Consequently, neither the TENV motor nor the TEAO motor would be
suitable for most general purpose applications, and, DOE believes they
are definite-purpose motors not covered by EPCA.
Integral Gearmotors
An ``integral gearmotor'' is an assembly of a motor and a specific
gear drive or assembly of gears, such as a gear reducer, as a unified
package. The motor portion of an integral gearmotor is not necessarily a
complete motor, since the end bracket or mounting flange of the motor
portion is also part of the gear assembly and cannot be operated when
separated from the complete gear assembly. Typically, an integral
gearmotor is not manufactured to standard T-frame dimensions specified
in NEMA MG1. Moreover, neither the motor portion, not the entire
integral gearmotor, are capable of being used in most general purpose
applications without significant modifications. An integral gearmotor is
also designed for a specific purpose and can have unique performance
characteristics, physical dimensions, and casing, flange and shafting
configurations. Consequently, integral gearmotors are outside the scope
of the EPCA definition of ``electric motor'' and are not covered under
EPCA.
However, an ``electric motor,'' as defined by EPCA, which is
connected to a stand alone mechanical gear drive or an assembly of
gears, such as a gear reducer connected by direct coupling, belts,
bolts, a kit, or other means, is covered equipment under EPCA.
IV. Electric Motors That Are Components in Certain Equipment
The primary function of an electric motor is to convert electrical
energy to mechanical energy which then directly drives machinery such as
pumps, fans, or compressors. Thus, an electric motor is always connected
to a driven machine or apparatus. Typically the motor is incorporated
into a finished product such as an air conditioner, a refrigerator, a
machine tool, food processing equipment, or other commercial or
industrial machinery. These products are commonly known as ``original
equipment'' or ``end-use equipment,'' and are manufactured by firms
known as ``original equipment manufacturers'' (OEMs).
Many types of motors used in original equipment are covered under
EPCA. As noted above, EPCA prescribes efficiency standards to be met by
all covered electric motors manufactured after October 24, 1997, except
that covered motors which require listing or certification by a
nationally recognized safety testing laboratory need not meet the
standards until after October 24, 1999. Thus, for motors that must
comply after October 24, 1997, once inventories of motors manufactured
before the deadline have been exhausted, only complying motors would be
available for purchase and use by OEMs in manufacturing original
equipment. Any non-complying motors previously included in such
equipment would no longer be available.
The physical, and sometimes operational, characteristics of motors
that meet EPCA efficiency standards normally differ from the
characteristics of comparable existing motors that do not meet those
standards. In part because of such differences, the Department is aware
of two types of situations where strict application of the October 24,
1997, deadline could temporarily prevent the manufacture of, and remove
from the marketplace, currently available original equipment.
One such situation is where an original equipment manufacturer uses
an electric motor as a component in end-use equipment that requires
listing or certification by a nationally recognized safety testing
laboratory, even though the motor itself does not require listing or
certification. In some of these instances, the file for listing or
certification specifies the particular motor to be used. No substitution
could be made for the motor without review and approval of the new motor
and the entire system by the safety testing laboratory. Consequently, a
specified motor that does not meet EPCA standards could not be replaced
by a complying motor without such review and approval.
This re-listing or re-certification process is subject to
substantial variation from one piece of original equipment to the next.
For some equipment, it could be a simple paperwork transaction between
the safety listing or certification organization and the OEM, taking
approximately four to eight weeks to complete. But the process could
raise more complex system issues involving redesign of the motor or
piece of equipment, or both, and actual testing to assure that safety
and performance criteria are met, and could take several months to
complete. The completion time could also vary depending on the response
time of the particular safety approval agency. Moreover, in the period
immediately after October 24, the Department believes wholesale changes
could occur in equipment lines when OEMs must begin using motors that
comply with EPCA. These changes are likely to be concentrated in the
period immediately after EPCA goes into effect on October 24, and if
many OEMs seek to re-list or re-certify equipment at the same time,
substantial delays in the review and approval process at the safety
approval agencies could occur. For these reasons, the Department is
concerned that certain end-user equipment
[[Page 322]]
that requires safety listing or certification could become unavailable
in the marketplace, because an electric motor specifically identified in
a listing or certification is covered by EPCA and will become
unavailable, and the steps have not been completed to obtain safety
approval of the equipment when manufactured with a complying motor.
Second, a situation could exist where an electric motor covered by
EPCA is constructed in a T-frame series or T-frame size that is smaller
(but still standard) than that assigned by NEMA Standards Publication MG
13-1984 (R1990), sections 1.2 and 1.3, in order to fit into a restricted
mounting space that is within certain end-use equipment. (Motors in IEC
metric frame sizes and kilowatt ratings could also be involved in this
type of situation.) In such cases, the manufacturer of the end-use
equipment might need to redesign the equipment containing the mounting
space to accommodate a larger motor that complies with EPCA. These
circumstances as well could result in certain currently available
equipment becoming temporarily unavailable in the market, since the
smaller size motor would become unavailable before the original
equipment had been re-designed to accommodate the larger, complying
motor.
The Department understands that many motor manufacturers and OEMs
became aware only recently that the electric motors addressed in the
preceding paragraphs were covered by EPCA. This is largely for the same
reasons, discussed above, that EPCA coverage of Category II motors was
only recently recognized. In addition, the Department understands that
some motor manufacturers and original equipment manufacturers confused
motors that themselves require safety listing or certification, which
need not comply until October 25, 1999, with motors that, while not
subject to such requirements, are included in original equipment that
requires safety listing or certification. Consequently, motor
manufacturers and original equipment manufacturers took insufficient
action to assure that appropriate complying motors would be available
for the original equipment involved, and that the equipment could
accommodate such motors. OEMs involved in such situations may often be
unable to switch to motors that meet EPCA standards in the period
immediately following October 24. To mitigate any hardship to purchasers
of the original equipment, the Department intends to refrain from
enforcing EPCA in certain limited circumstances, under the conditions
described below.
Where a particular electric motor is specified in an approved safety
listing or certification for a piece of original equipment, and the
motor does not meet the applicable efficiency standard in EPCA, the
Department's policy will be as follows: For the period of time necessary
for the OEM to obtain a revised safety listing or certification for that
piece of equipment, with a motor specified that complies with EPCA, but
in no event beyond October 24, 1999, the Department would refrain from
taking enforcement action under EPCA with respect to manufacture of the
motor for installation in such original equipment. This policy would
apply only where the motor has been manufactured and specified in the
approved safety listing or certification prior to October 25, 1997.
Where a particular electric motor is used in a piece of original
equipment and manufactured in a smaller than assigned frame size or
series, and the motor does not meet the applicable efficiency standard
in EPCA, the Department's policy will be as follows: For the period of
time necessary for the OEM to re-design the piece of equipment to
accommodate a motor that complies with EPCA, but in no event beyond
October 24, 1999, the Department would refrain from enforcing the
standard with respect to manufacture of the motor for installation in
such original equipment. This policy would apply only to a model of
motor that has been manufactured and included in the original equipment
prior to October 25, 1997.
To allow the Department to monitor application of the policy set
forth in the prior two paragraphs, the Department needs to be informed
as to the motors being manufactured under the policy. Therefore, each
motor manufacturer and OEM should jointly notify the Department as to
each motor they will be manufacturing and using, respectively, after
October 24, 1997, in the belief that it is covered by the policy. The
notification should set forth: (1) The name of the motor manufacturer,
and a description of the motor by type, model number, and date of design
or production; (2) the name of the original equipment manufacturer, and
a description of the application where the motor is to be used; (3) the
safety listing or safety certification organization and the existing
listing or certification file or document number for which re-listing or
re-certification will be requested, if applicable; (4) the reason and
amount of time required for continued production of the motor, with a
statement that a substitute electric motor that complies with EPCA could
not be obtained by an earlier date; and (5) the name, address, and
telephone number of the person to contact for further information. The
joint request should be signed by a responsible official of each
requesting company, and sent to: U.S. Department of Energy, Assistant
Secretary for Energy Efficiency and Renewable Energy, Office of Building
Research and Standards, EE-41, Forrestal Building, 1000 Independence
Avenue, SW., Room 1J-018, Washington, DC 20585-0121. The Department does
not intend to apply this policy to any motor for which
[[Page 323]]
it does not receive such a notification. Moreover, the Department may
use the notification, and make further inquiries, to be sure motors
listed in the notification meet the criteria for application of the
policy.
This part of the Policy Statement will not apply to a motor in
Category II, discussed above in Section III. Because up to 24 months is
contemplated for compliance by Category II motors, the Department
believes any issues that might warrant a delay of enforcement for such
motors can be addressed during that time period.
V. Further Information
The Department intends to incorporate this Policy Statement into an
appendix to its final rule to implement the EPCA provisions that apply
to motors. Any comments or suggestions with respect to this Policy
Statement, as well as requests for further information, should be
addressed to the Director, Building Technologies, EE-2J, U.S. Department
of Energy, Forrestal Building, 1000 Independence Avenue, SW.,
Washington, DC 20585-0121.

correction notice of January 20, 1998, except as follows:
[[Page 325]]
(i) Page 8, subclause 5.1.1., Specified temperature, the
introductory clause does not apply. Instead the following applies:
The specified temperature used in making resistance corrections
should be determined by one of the following (Test Method B only allows
the use of preference (a) or (b).), which are listed in order of
preference.
(ii) Page 17, subclause 6.4.1.3., No-load test, the text does not
apply. Instead, the following applies:
See 5.3 including 5.3.3, the separation of core loss from friction
and windage loss. Prior to making this test, the machine shall be
operated at no-load until the input has stabilized.
(iii) Page 40, subclause 8.6.3, Termination of test, the third
sentence does not apply. Instead, the following applies:
For continuous rated machines, the temperature test shall continue
until there is 1 [deg]C or less change in temperature rise over a 30-
minute time period.
(iv) Page 47, at the top of 10.2 form B, immediately after the line
that reads ``Rated Load Heat Run Stator Winding Resistance Between
Terminals,'' the following additional line applies:
Temperature for Resistance Correction (ts) = - [deg]C
(See 6.4.3.2).
(v) Page 47, at the bottom of 10.2 Form B, after the first sentence
to footnote tt, the following additional sentence applies:
The values for ts and tt shall be based on the
same method of temperature measurement, selected from the four methods
in subclause 8.3.
(vi) Page 47, at the bottom of 10.2 Form B, below the footnotes and
above ``Summary of Characteristics,'' the following additional note
applies:
Note: The temperature for resistance correction (ts) is
equal to [(4) - (5) + 25 [deg]C].
(vii) Page 48, item (22), the torque constants ``k = 9.549 for
torque, in N[middot]m'' and ``k = 7.043 for torque, in 1bf[middot]ft''
do not apply. Instead, the following applies:
``k2 = 9.549 for torque, in N[middot]m'' and
``k2 = 7.043 for torque, in 1bf[middot]ft.''
(viii) Page 48, at the end of item (27), the following additional
reference applies:
``See 6.4.3.2.''
(ix) Page 48, item (29). ``See 4.3.2.2, Eq. 4,'' does not apply.
Instead the following applies:
