EISA Basics
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.
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.

Rebates
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 motor
Must 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 purchase of higher efficiency motors instead of repairing older, less efficient motors.
Details regarding acceptable “evidence” of purchase and disposal have not yet been defined.

EISA Rules Summary
Start:
If motor has one (or more) of these features, it is exempt and can be Standard Efficiency
Voltage over 600v Single phase Frequencies other than 60Hz or 60/50Hz Design D and Ultra High Slip (UHS) motors Multispeed 10 Pole and higher pole count Encapsulated winding Frequency other than 60Hz Frame Size - nonNEMA, 56Fr and smaller Special Base or Feet Thrust Bearings Sleeve Bearings Non-NEMA (custom) flange / bracket / endshield Non-standard shaft dimensions (non-NEMA) Integral Gear Motor Saw Arbor TENV, TEBC, DPFV TEAO or Open Air Over Non-Continuous / Intermittent Phase converters Brake (installed, not provisions only) NEXT
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)
201-500hp Voltages other than 230v, 460v but <601v (all 60Hz) Design C 8 Pole NEMA U or US shaft Footless or Round body Close Coupled Pump Vertical Normal Thrust Firepump N E X T
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. © 2009 Regal Beloit Corporation. All rights reserved.
208v, 208-230v, 208-230/460v
Motors that would need to meet NEMA Premium because they are otherwise General Purpose A 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 features A 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.

Why Should I Upgrade?
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: Over a 20 year life this is $18,600 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.

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.
2.
3.
4.
We will compile a list of the motors that you purchased in the last 12 months.
We will help analyze the cost and benefits of upgrading each motor. We will match those models to the new model number.
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!

Worldwide Energy Standards 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
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
IE1 IE2 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.
