SUPPLEMENTARY INFORMATION:

1. Authority.

Part .3 of Title IV of the National Energy lonservation Policy Act of

1978 (NECPA), Public Law 95-619, amends the Energy Policy and Conservation Act

of 1975 (EPCA) to add "Energy Efficiency of Industrial Equipment," which

includes electric motors. The most recent amendment to EPCA, the Energy

Policy Act of 1992 (EPAct), Public Law 102-486, promulgates definitions

related to electric motors in §122(a), 106 Stat. 2807, test procedures for

motor efficiency in §122(b), 106 Stat. 2809, labeling for electric motors in

§122(c), 106 Stat. 2809, standards for nominal full-load efficiency in

§122(d), 106 Stat. 2814, and certification of compliance by manufacturers in

§122(e), 106 Stat. 2817.

Section 122(a)(3) of the EPAct (EPCA, §340(13)(A), 42 U.S.C. §6311

(13)(A)), defines "electric motor" as any motor which is "general purpose T -

frame, single-speed, foot- mounting ,- polyphase squirrel-cage induction of the

National Electrical Manufacturers Association (NEMA) Designs A and B,

continuous-rated, operating on 230/460 volts and constant 60 Hertz line power,

as defined in NEMA Standards Publication MG1-1987. " Section 122(d) of the

EPAct (EPCA, §342(b)(1), 42 U.S.C. §6313(b)(1)), prescribes standards for

electric motors that are 1 through 200 horsepower, and "manufactured (alone or

as a component of another piece of equipment)," except for "definite purpose

motors, special purpose motors, and those motors exempted by the Secretary."

Section 122(b)(1) of the EPAct (EPCA, §343(a)(5)(A), 42 U.S.C. §6314

(a)(5)(A)), requires that testing procedures for motor efficiency shall be the

test procedures specified in NEMA Standards Publication MG1-1987, and the

Institute of Electrical and Electronics Engineers (IEEE ) Standard 112 Test

Method B for motor efficiency, as in effect on October 24, 1992. Section

122(b)(1), EPCA §343( a)(5)(B) and ( C), provide for amendment of the testing

procedures if the test procedures in the NEMA and IEEE standards are'revised.

Section 122(c)(4) of the EPAct (EPCA, §344(d), 42 U.S.C. §6315(d))

directs the Secretary, after- consultation with the Federal Trade Commission,

see EPCA §344(f), 42'U.S.C. §6315(f), to prescribe rules . requiring motor

labeling .to indicate energy efficiency on the permanent nameplate , to display

that motor- energy efficiency prominently in catalogs and other marketing

materials , and to include other markings to facilitate enforcement of the

energy efficiency standards.

Section 122(e)(2) of the EPAct (EPCA, §345(c), 42 U.S.C. §6316(c))

requires manufacturers to certify compliance with energy efficiency standardsthrough an independent testing or certification program nationally recognized

in the United States.

2. Background.

The Department of Energy is drafting a proposed rule to implement the

EPAct requirements for motors. . However, the. language of the EPAct raises

several issues regarding definitions , testing,, labeling, and certification.

Q:\CE-40 \ CE-43\43COMMON \ RABA\MOTOR03.MTG

May 11, 1995

EE-RM-95-400 COMMENT 0A
The purpose of the public meeting is to discuss these issues, gather

information, and seek early resolution.

Discussion.

The Department is interested in receiving information and statements to

help resolve the following issues:

a. Definitions.

1) Metric Equivalents. Section 122(d) of the EPAct (EPCA,'

§342(b)(1), 42 U.S.C. §6313(b)(1)) lists standards for electric motor nominal

full-load efficiency ratings corresponding to horsepower and number of poles.

Additionally, .§205b. of the Metric Conversion Act of 19.75, Public Law 94-168,

15 U.S.C. 205b., states "the declared policy of the United States- (1) to

designate the metric system of measurement as the preferred system of weights

and measures for United States trade and commerce; (2) to require that each

Federal-agency, by 'a date certain and to the extent economically feasible by

the end of the fiscal year 1992, use the metric system of measurement in its

procurementsr grants, and other business-related activities, except to the

extent that such use is impractical or is likely to cause significant

inefficiencies or loss of markets to United States firms, such as when foreign

competitors are producing competing products in non-metric units." This

policy is promulgated in Executive Order 12770 of July 25, 1991, "Metric Usage

in Federal Government Programs." 56 FR 35801-03 (July 29, 1991). The

Department seeks advice on how to implement these statutes with respect to

motors under the EPAct. Specifically, should the energy efficiency_rules

Q:\CE-40\CE-43\43COMMON\RABA\MOTOR03.MTG

5 - May 11, 1995

EE-RM-95-400 COMMENT 0A
identify,kilowatt ratings equivalent to corresponding horsepower ratings, and

other electrical and mechanical equivalents? If so how?

2) Basic Model. The Code of Federal Regulations (CFR ), in 10 CFR

Part 430 §430.2, provides a definition for the term " basic model " in regard

to the appliance program : " Basic model means all un its of a given type of

covered product ( or class thereof ) manufactured by one manufacturer and--

...[as to dishwashers , for example] which have electrical characteristics that

are essentially identical , and which do not'have any differing physical or

functional characteristics that affect energy consumption ." Basic model is a

term used to describe a product or item of equipment whose performance,

design, mechanical , and functional characteristics are essentially the same.

Components of similar design may be substituted in a basic model without

requiring additional testing if the represented measures of energy consumption

continue to satisfy applicable provisions for sampling and testing. In the

case of electric motors , a manufacturer may produce one basic model and

thousands more of other model numbers that are essentially the same, all based

on variations in design features that do not affect energy efficiency.

The Department is considering defining the term " basic model" in

its coverage of electric motors to . mean all units of a given type of covered

equipment. ( or class thereof ) manufactured by a single manufacturer , and, with

respect to electric motors , having the'same rating , electrical design

characteristics that are essentially identical , and no differing mechanical or

functional characteristics that affect energy consumption or efficiency. The

Q:\CE-40\CE,- 43\43COMMON\ RABA\MOTOR03.MT6

6 - May 11, 1995

EE-RM-95-400 COMMENT 0A
Department solicits the views of interested parties as to whether the

Department should adopt such a definition.

3) Definite Purpose Motor. Under Section 122(d) of the EPAct

(EPCA §342(b)(1), 42 U.S.C. §6313(b)(1)), the energy efficiency standards for

electric motors do not apply to "definite purpose motors." Section 122(a)(3)

of the EPAct (EPCA §340(13)(B), 42 U.S.C. §6311(13)(B)) defines a "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 which cannot be used in most general purpose applications."

However, the EPAct does not define the term "service conditions other than

usual. " Therefore, the Department is considering developing a definition for

this term that will take into consideration adverse environmental and

operating conditions, such as exposure to abrasive or combustible dusts,

chemical fumes, nuclear radiation, salt-laden air, abnormal shock or

vibration, unbalanced supply voltage, power system not grounded, frequent

starting, frequent short circuits , and so forth. The Department seeks advice

in. developing a definition for "service conditions other than usual."

b. Testing.

1) Canadian Standards Association Standard C390. Section

122(b)(1) of the EPAct (EPCA, §343(a)(5)(A), 42 U.S.C. §6314(a)(5)(A)) states

that "the test procedures shall be the test procedures specified in NEMA

Standards Publication MG1-1987 and IEEE Standard 112 Test Method B for motor

Q:\CE-40\ CE-43\43COMMON\RABA\MOTOR03.MTG,

7 May 11. 1995

EE-RM-95-400 COMMENT 0A
efficiency, as in effect on the date of the enactment of the Energy Policy Act

of 1992. " Subsequently, the NEMA Standards Publication MG1-1987 was revised

and superseded by MG1-1993 on November 19, 1992, and published in October-19,93

as MG1-1993. A further amendment, Revision 1 to MG1-1993, was added on

December 7, 1993.

The EPAct ( 42 U.S.C. §§6314(a)(5)(B) and ( C)) provides for

amending the established test procedures if the -test ,procedures in NEMA

Standards Publication MG1-1987 and IEEE Standard 112 Test Method B are

amended. MG1-1993 with Revision 1, section MG1-12.58 .1 states: "Efficiency

and losses shall be determined in accordance with IEEE Std 112 or Canadian

Standards Association Standard C390. " In considering whether to amend the

motor efficiency test procedures specified in NEMA Standards'Publication MG1-

1987 in order to require the motor efficiency test procedures specified in

NEMA Standards Publication MG1-1993 with Revision 1, the Department hereby

solicits information on the affect of the additional reference to Canadian

Standards Association Standard C390.

2) Testing Sampling Plan. Section 122(d) of the EPAct (EPCA,

§342(b), 42 U.S.C. §6313(b)) requires each electric motor to have a certain

"nominal full load efficiency," which is defined in §122(a)(3) of the EPAct

(EPCA §340(13)(H), 42 U.S.C. 6311(13)(H)) as the average efficiency of a

population of motors of duplicate design as determined in accordance with NEMA

Standards Publication MG1-1987. NEMA Standards Publications MG1-1987 and MGi

1993 with Revision .1 both provide for the determination of.nominal.full load

efficiencies that are to represent the average efficiency *of a large

8 - Q:\CE-40\CE-43\43COMMON\ RABA\MOTOR03.MTG

May 11, 1995

EE-RM-95-400 COMMENT 0A
population of motors of duplicate design, and a corresponding minimum

efficiency that any motor must equal or exceed to be rated at the

corresponding nominal efficiency. The DOE contemplates establishing a testing

sampling plan to reasonably ensure that the results from testing a few motors

will establish the average efficiency of the large population of motors of

duplicate design. This could be done by requiring the testing of a sufficient

number of motors of f a,parti`cular model, selected at random, so that an

estimate at the 95 percent statistical confidence level can be made both that

the motors of this model offered for sale have both a mean efficiency equal to

or greater than the nominal efficiency given in NEMA Standards Publication

MG1-1993 Revision 1 for this rating, and also that at least 99 percent of

these motors of this same particular model have efficiencies equal to or

greater than the minimum efficiency associated with the nominal efficiency

given for this motor in'the NEMA Standards Publication MG1-1993 Revision 1.

The Department seeks advice on what type of sampling plan should be adopted.

3) Alternative Method of Efficiency Determination. In the case

where a manufacturer produces hundreds of different basic models of electric.

motors, it may be neither technically feasible, nor economically justifiable

to test all basic models for compliance. For such situations, the Department

is considering the use of predictive mathematical calculations and statistical,

methodologies developed from scientific and engineering analyses that are

substantiated by actual test data in order to calculate the efficiency, i.e.

total power losses, for-some basic models of electric motors. Such

"alternative efficiency determination methods," engineering or statistical

analyses, would require support by actual testing of some minimum number of

Q:\CE-40\CE-43\43C O 'iON\RABA\MOTOR03.MTG

May 11, 1995

EE-RM-95-400 COMMENT 0A
basic models and would.incorporate computer simulations, modeling, or other

mathematical evaluations of performance data. The alternate efficiency

determination method to verify compliance for motors is similar to the method

used in the appliance program, 10 CFR Part 430, §430.24(m)(2)(.ii), that

permits manufacturers of central air conditioners to verify compliance by use

of an "alternative rating method."

The Department solicits views on both the feasibility of testing

all models of motors, as well as appropriate alternative methods for

determining efficiency in the event it is not feasible to test all models.

c. . Labeling. Section 122(c)(4) of the EPAct (EPCA , §344(d), 42 U.S.C.

§6315(d)) -requires the following: (1) "not later than 12 months after the

Secretary establishes test procedures for electric motors-...the Secretary

shall prescribe labeling rules.. .taking into consideration NEMA Standards

Publication MG1-1987;" and (2) such labeling rules shall "(1) indicate the

energy efficiency of the motor on the permanent nameplate attached to such

motor; (2) prominently display the energy efficiency of the motor in equipment

catalogs and-other material used to. market the equipment; and (3) include such

other markings as the Secretary determines necessary, solely to facilitate

enforcement of the standards."

Based upon these EPAct requirements, the Department 'is considering the

required use of a distinct logo, such as lower case letters."ee"-within a

circle,-to identify motors that are manufactured as energy-efficient and in

compliance with the EPAct. Such a logo would be permanently marked on the

10 - Q:\CE-40\CE-43\43COhMON\RA9A\MOTOR03.MTG

May 11, 1995

EE-RM-95-400 COMMENT 0A
motor nameplate to facilitate'enforcement, be prominently displayed on

packaging , in shipping documents, in customs and commercial documents, and

other materials. The Department is also considering a requirement of

permanent markings on the motor nameplate of both the nominal efficiency and

the minimum efficiency associated with that nominal efficiency, and of -

prominent displays of both the nominal and minimum efficiency values in

catalogs to assist purchasers in making purchasing decisions.

In addition, §122(c)(4) of the EPAct (EPCA, §344(c), 42 U.S.C.

§6315(c)) authorized additional required displays of.information about

electric motorenergy efficiency that are likely to assist purchasers in

making purchasing decisions, including instructions for maintenance, use,. or

repair of the motor, and information on energy use. Thus, the Department is

also considering use of a label(s) or marking(s) that bear(s)'the following

statement(s): (1) "This motor complies with energy efficiency requirements in'

the Energy Policy Act of 1992 at the time of original manufacture, [DATE]."_or

"Efficiency complies with,EPACT at time of. manufacture, [DATE]."; (2) "Consult

the manufacturer for maintenance, use, or repair." or "Repair only in factory

authorized-shop."; and (3) "Estimated kilowatts used after 2000 hours'

continuous operation according to manufacturer's ratings: or "Est.

annual kW used: ". (Annual would be defined as ".2000 hours continuous.,

operation according to manufacturer's ratings.") -

The Department seeks advice on whether such label(s) or marking(s) would

assist purchasers, and on the content, design, size, location, and attachment

of such label(s) or marking(s).

EE-RM-95-400 COMMENT 0A
d. Certification. Section 122(e)(2) of the EPAct (EPCA §345(c), .42 U.S.C.

§6316(c)) requires "manufacturers to certify, through an independent testing

or certification program nationally recognized in the United States, that such

motor meets the applicable [nominal full=load efficiency standard]."

1) Compliance. The Department is considering implementation of the

EPAct requirement for "manufacturers to certify" by means of a compliance

statement and certification report that each basic model of energy efficient

electric motor meets the requirements of the EPAct. This is similar to 10

C.F.R. Section 430.62(a), which sets forth the appliance program procedures to

.be followed for certification by requiring each manufacturer to "certify by

mean's of a compliance statement and certification report that each basic model

meets the requirements of that standard." A manufacturer's compliance

statement and certification report for each basic model of energy efficient

electric motor would be based, at least in part, upon actual testing or an

alternative efficiency determination method. The Department solicits the

views of interested parties on such a requirement.

2) Independent Testing and Certification. The Department. is also

considering how to interpret and implement the EPAct requirement for

"manufacturers-to certify, through an independent testing or certification

program nationally recognized in the United States, that such motor meets the

applicable [nominal full-load efficiency standard]." Such testing or

certification programs could be operated by commercial laboratories,

government laboratories, and trade associations. The Department seeks

information as to the identity, nature, and capabilities of any nationally

Q:\CE-40\CE-43\43COMN1ON\RABA\ MOTORO3.MTG

- 12 - May 11. 1995

EE-RM-95-400 COMMENT 0A
recognized program(s) for the testing and certification of motors. The

Department is aware that the Association of Home Appliance Manufacturers

conducts a program to verify manufacturers' certifications of.the total.

refrigerated volume of refrigerators and the energy efficiency values of room

air conditioners; that the Gas Appliance Manufacturers As-sociation conducts a

testing program to verify manufacturers' certifications of the energy

efficiency of water heaters, furnaces, room heaters, and boilers; and that the

Air Conditioning and Refrigeration Institute conducts a testing program to

verify manufacturers' certifications of the energy efficiency and other,

performance criteria of residential and commercial air conditioning and heat

pump systems. The Department seeks information on any similar existing

programs that certify or verify the performance characteristics. of motors. In

addition, the Department seeks information as-towhether foreign commercial

laboratories, foreign government laboratories, or trade associations operate

such programs.

The Department also seeks advice concerning two other possible issues

under §122(e) of the EPAct (EPCA §345(c), 42 U.S.C. §6316(c)). First,

questions may arise as to what constitutes "an independent testing or

certification program [that is] nationally recognized." The Department seeks

input as to the criteria by which an -organization should be considered

competent (1) to conduct the specific tests or calibrations for motors

according to the required test procedures, and (2) to operate a certification

program. One possibility is that th-e.Department could consider a motor

testing or certification program to be "nationally recognized" if the program

were accredited by the National Institute of Standards and Technology/National

Voluntary Laboratory Accreditation Program (NIST/NVLAP). The Department seeks

views on such an approach, including the question of whether a foreign program

recognized by NIST/NVLAP should be considered "nationally recognized in the

United States." Second, the Department seeks views as to whether

manufacturers are permitted to self-test or self-certify the energy efficiency

of their own motors, and, if so, under what circumstances.

e. Identification of Other Issues. The Department will seek to resolve the

above issues in developing a proposed rule. In addition, there may be other

issues that the Department will need to address. The purpose of the meeting

is to identify all of these various 'issues and to begin dialogue with

interested parties to help resolve them.
