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 sell motors built after December 19,
2010 with a lower nameplate efficiency than EISA allows. EISA applies to both NEMA and IEC motors with
features described in the details of the law.
EISA allows motors that are considered “finished goods” or are shipped from the factory before
December 19, 2010 to be sold after December 19, 2010.
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 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 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 has passed the House of Representatives and is expected to be voted on
by the Senate fall, 2009.
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.
Timing
Planned effective date no later than Jan 1st, 2010 and lasts for five years.

EISA Rules Summary
Start
If motor has one (or more) of these features, it is
exempt and can be Standard Efficiency
Voltage over 600v
Design D and Ultra High Slip (UHS) motors
Multispeed
10 Pole and higher pole count
Encapsulation
Frequency other than 60Hz
Frame Size - nonNEMA, 56Fr and smaller
Special Base or Feet
Thrust Bearings
Sleeve Bearings
Endshield/Bracket Customer Defined
Non-standard shaft dimensions (non-NEMA)
Integral Gear Motor
Saw Arbor
TENV, TEBC, DPFV
TEAO or ODP Air Over
Non-Continuous / Intermittent
Brake (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)
201-500hp
Voltages other than 230v, 460v but <601v (all 60Hz)
Design C
8 Pole
Frame Size - NEMA U
Footless
Close Coupled Pump
Vertical Normal Thrust
Firepump
If motor does not have any
features from the Standard
Efficiency section or EPACT
section, then it must meet NEMA
Premium (Table 12-12)

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:
Example: 100hp 1800rpm ODP motor
Over a 20 year life
this is $18,600
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.
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. Watch for updates
to this presentation, to include a payback calculator.
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!

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 EFF2, not a direct match
IE2 is based upon EFF1, not a direct match
IE4
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
IE3
IE2
IE1 60Hz is equal to Brazil’s level
IE2 60Hz is the same as EPACT
IE3 60Hz is the same as NEMA Premium
IE1
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.
