Revised 6/15/10"These materials are intended to provide general information (not legal or other advice) about important new legislation or developments. These materials are not intended to substitute for a thorough analysis of the subject covered or any subsequent developments relating to that subject.“.


EISA (Public Law 110-140) was signed by President Bush on December 19, 2007 and will become effective

on December 19, 2010.

Beginning on December 19, 2010, motor manufacturers may not build motors with a lower nameplate

efficiency than EISA allows. EISA applies to both NEMA frame motors and the equivalent IEC frame motor.

Motors that are built before December 19, 2010 but are held in inventory or are in transit can be sold,

this deadline applies only to build dates.

EISA Basics

General Overview of Levels General Purpose NEMA & IEC motors that today need to meet EPAct efficiency, will need to

meet the NEMA Premium® efficiency levels (Table 12-12) beginning on December 19, 2010

General Purpose NEMA & IEC motors that were exempt from EPAct because of voltage,

mounting, etc. will need to meet EPAct efficiency (Table 12-11) beginning on December 19, 2010

NEMA & IEC motors that are not considered “General Purpose” (i.e., motors that cannot be used

in most applications, such as special shafts, blowers or nonstandard frequencies, nonstandard

volts/Hz) remain exempt from EISA regulations for efficiency.


On March 31, 2009, the U.S. Senate Energy and Natural Resources Committee adopted a provision

that creates a motor rebate program for premium efficiency motors, known as the “crush for credit”

program. This proposal passed the House of Representatives but did not go before the Senate for voting.

It is possible that a form of the proposed rebates below could still go before the Senate but it has not yet.

Proposed Rebates$25 per horsepower for the purchase of NEMA Premium motors

Must demonstrate evidence that the user purchased an electric motor that meets the new requirements to replace an installed (existing) motor.

$5 per horsepower for the disposal of the old inefficient motorMust demonstrate evidence that the entity removed the installed motor from service and properly disposed of the old motor and nameplate.

It is intended to offset the cost of purchasing a new, more efficient motor and to encourage the purchaseof higher efficiency motors instead of repairing older, less efficient motors.

Details regarding acceptable “evidence” of purchase and disposal have not yet been defined.

Rebates


EISA Rules Summary

If motor has one (or more) of these features, it is exempt and can be Standard Efficiency

Voltage over 600vSingle phaseFrequencies other than 60Hz or 60/50HzDesign D and Ultra High Slip (UHS) motorsMultispeed10 Pole and higher pole countEncapsulated windingFrequency other than 60HzFrame Size - nonNEMA, 56Fr and smallerSpecial Base or FeetThrust BearingsSleeve BearingsNon-NEMA (custom) flange / bracket / endshieldNon-standard shaft dimensions (non-NEMA)Integral Gear MotorSaw ArborTENV, TEBC, DPFVTEAO or Open Air OverNon-Continuous / IntermittentPhase convertersBrake (installed, not provisions only)

If motor does not have any features from the Standard Efficiency section but does have one or

more of the following features, it must meet EPACT (Table 12-11)

Start:

If motor does not have any features from the Standard Efficiency section or EPACT

section, then it must meet NEMA Premium (Table 12-12)

Note: NEMA frames and IEC equivalents are included in the categories

above – use other features to determine efficiency level.


208v, 208-230v, 208-230/460v

Motors that would need to meet NEMA Premium because they are otherwise General PurposeA spread voltage rating of 208-230v would require compliance to NEMA Premium (Table 12-12) at 230v and compliance with EPACT efficiency (Table 12-11) at 208v

A spread voltage rating of 208-230/460v would require compliance to NEMA Premium (Table 12-12) at 230v and460v and compliance with EPACT efficiency (Table 12-11) at 208v

If the design doesn't comply with the 12-11 levels at 208 volt then, it would be acceptable to use "Operational at 208 volt at ## Max. Amps" on the blank line of the nameplate.

Motors that would need to meet EPACT because of mounting or other featuresA spread voltage rating of 208-230v would require compliance to EPACT efficiency (Table 12-11) at both 208v and 230v

A spread voltage rating of 208-230/460v would require compliance to EPACT efficiency (Table 12-11) at 208v, 230v and 460v.


Examples of EISA Rules

Example #1:

Motor ABC is an EPACT motor (12-11) with rating 100hp 230/460v, 60Hz, 405T 1800rpm, TEFC,

standard bracket, horizontal, rigid base.

Beginning on December 19, 2010 it can no longer be sold because it is a General Purpose NE MA motor

and will not meet the efficiency requirements under EISA.

EISA requires that this model must meet NEMA Premium efficiency standards. Increasing the

efficiency of this motor would require a design change.

Example #2:

Motor XYZ is the same as ABC except it has space heaters and a special 13.75” shaft extension.

The special shaft extension makes motor XYZ exempt from the EISA requirements, therefore, it can

continue to be purchased after December 19, 2010 without a design change or a substitute motor.


If my older, less efficient motor fails, why should I upgrade an Exempt motor to NEMA

Premium instead of rewinding the old motor?

Higher efficiency motors:

1) Reduce the operating costs and less stress on utilities, supporting Green initiatives.

2) Generally operate at a lower temperature and for every 10°C reduction in operating temperature, insulation life doubles.

3) Are generally quieter (smaller fans).

4) Have lower vibration with lower bearing temperatures for longer bearing life.

5) Earn a rebate.

Comparison of Operating Cost:

Example: 100hp 1800rpm ODP motor

Operating 24 hrs/day, 240 days/year at a cost of $0.08 per kW-hr

Standard efficiency motor with 93% versus NEMA Premium motor with 95.4%

Standard efficiency motor uses $36,963 worth of electricity per year to operate

NEMA Premium motor uses $36,033 worth of electricity per year to operate

In addition to direct energy cost savings, maintenance and downtime will be reduced.

Why Should I Upgrade?

Over a 20 year lifethis is $18,600


What can Marathon Electric do for Me?

Our Sales and Engineering teams can help ensure compliance with the new EISA

requirements and with your own internal energy initiatives:

1. We will compile a list of the motors that you purchased in the last 12 months.

2. We will help analyze the cost and benefits of upgrading each motor.

3. We will match those models to the new model number.

4. For motors that do not yet have a new model with all of the same features, we will work with you to establish the new model.

For special motors that will still be exempt under EISA, consider upgrading to save operating

cost over the life of the motor.

Some applications may have size, weight or performance constraints - - now is the

time to consider these special conditions.

Watch for other innovative solutions from your motor energy saver, Marathon Electric!


NO LEGISLATION by IEC - - Voluntary Compliance

2/1518/FDIS document issued in Sept 2008 defines levels for IE1, IE2, IE3

IE4 is not defined but is reserved for Super Premium

50Hz

IE1 is based upon old EFF2, not a direct match

IE2 is based upon old EFF1, not a direct match

IE3 is based upon 15% to 20% lower losses than IE2

NEMA Table 12-14 for 50Hz was revised in 2009 to match IE3

60Hz

IE1 60Hz is equal to Brazil’s level

IE2 60Hz is the same as EPACT

IE3 60Hz is the same as NEMA Premium

British Columbia, Canada will match EISA - - January 1, 2011

Natural Resources Canada (NRCan) proposed change for all of Canada.

Expect decision after April 20, 2009.
