The Future of Energy
And
Motor Efficiency

EISA Basics
EISA is the acronym for the Energy Independence & Securities Act
This law was signed on December 19, 2007 and will be enforced beginning on December 19, 2010
On December 19, 2010, motor manufacturers may not build motors that have a lower nameplate
efficiency than the rules allow.
Motors that are considered “finished goods” or are shipped from the factory before December 19, 2010
can be sold after December 19, 2010 because they were built before the deadline.
General Overview of Levels

General Purpose motors that today need to meet EPACT, will need to meet the NEMA
Premium efficiency levels in 2010

General Purpose motors that were exempt from EPACT because of voltage, mounting, etc
will need to meet EPACT in 2010

Motors that cannot be used in most applications, such as special shafts, blowers or
nonstandard frequencies, are exempt from any regulations for efficiency.
Specific EISA Rules
Exempt / Not Covered
Single phase
Special shaft extensions
TEBC, TEAO, DPFV, TENV
Special V/Hz inverter motors
Non-continuous duty
Design D
Phase converters
Multi-speed
50Hz
Two-digit frames (48, 56)
Must meet EPACT (Table 12-11)
Close Coupled Pump
Vertical Solid Shaft
Round body
Nonstandard Voltages, 60Hz
200-500hp
Firepump motors
U-frame
Must meet NEMA Premium (Table 12-12)
1-200hp
Design A & B
C-face, D-flange
Footed
Voltages covered by EPACT (60Hz)
Note: Frame size is not an exemption.
If a motor is an IEC frame, follow the rules just as if it was a NEMA Frame.
If a motor is above a NEMA frame (680), follow the rules just as if it was a 440 frame.
Model vs Rule
 THE EFFICIENCY VALUE FOR A GIVEN MODEL WILL NOT CHANGE 
 THE EFFICIENCY LEVEL IS WHAT IT IS 
 ONLY THE RULES FOR USING A PARTICULAR MOTOR WILL CHANGE 
EPACT efficiency levels / values are the same now as they will be in 2010 - NEMA MG1 Table 12-11
NEMA Premium efficiency levels / values are the same now as they will be in 2010 - NEMA MG1 Table 12-12
How to Check a Model for Compliance / Changes
1. Check the model details to see what features it has. What makes the motor NOT general purpose?
Voltage, frequency, feet, vertical mounting, etc.
2. Look at the rules on the previous slide or use the flowchart on the next page. Are any of those
features still considered special? If not, the motor must meet EPACT or NEMA Premium.

Examples
Example #1:
Motor 405TTFS4036 is an EPACT motor. After Dec 19, 2010 it can no longer be built because
it is a General Purpose motor (230/460v, 60Hz, 405T, standard bracket, horizontal, rigid base)
The rules state that this model must meet NEMA Premium. Increasing efficiency requires a
design change.
There is already a NEMA Premium design available with model 405TTFS6036 so rather than
redesign the EPACT motor 405TTFS4036, we should offer model 405TTFS6036 instead.
Example #2:
Motor 405TTFS1234 is the same as 405TTFS4036 except it has space heaters and a special
13.75” shaft extension. The space heaters are irrelevant in terms of efficiency. The special
shaft extension makes it exempt from the EISA legislation, therefore, it can be standard efficiency.
Why Should I Upgrade?
Why should I upgrade an Exempt motor to NEMA Premium instead of rewinding?
Higher efficiency motors reduce the operating costs
Higher efficiency motors put less stress on utilities, supporting Green initiatives.
Comparison of Operating Cost:
Example: 100hp 1800rpm ODP motor
Operation 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 costs $36,963 per year to operate
NEMA Premium motor costs $36,033 per year to operate
Over a 20 year life
this is $18,600
Consider the impact this has on a steel mill or paper mill that uses hundreds of motors of all sizes
for both core equipment and auxiliary equipment like material handlers, air movers, chillers,
packaging equipment…!!
What can Regal-Beloit do for Me?
Our Sales and Engineering teams can help ensure compliance with the new efficiency
legislation 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. With special model numbers, it may be
possible to keep the same model number when redesigning the motor to a higher
efficiency level
For special motors that will still be exempt in 2010, 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.
European Actions - IEC
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
IE4
IE2 is based upon EFF1, not a direct match
IE3 is based upon 15% to 20% lower losses than IE2
IE3
NEMA Table 12-14 currently meets or exceeds IE3
but may be changed to match IE3
IE2
60Hz
IE1 60Hz is equal to Brazil’s level
IE2 60Hz is the same as EPACT
IE3 60Hz is the same as NEMA Premium
