Energy Legislation and Its Impact On Motors
On December 19, 2010, new energy legislation will take effect impacting the manufacturing of certain industrial motors. The Energy Independence and Security Act of 2007 (EISA) legislation sets stringent new efficiency standards for a broad range of General Purpose and some Definite Purpose 3-phase motors. Motor designs which do not meet the legislation requirements can no longer be manufactured after December 19, 2010. Existing inventory of affected motors will be available until quantities are depleted.
Grainger offers a complete line of compliant, higher efficiency motor alternatives to the models being phased out. These new energy efficient motors offer a variety of long-lasting benefits:
- Helps reduce energy and operating costs (See calculator)
- Generally operate at a lower temperature which helps prolong motor life.
- Lower vibration designs help promote longer bearing life

New Energy Legislation Coverage
The EPAct 2007 legislation separates the motors covered by the policy into 2 groups: Subtype 1 and Subtype 2. Here is a listing of the two groups covered by the policy:
Subtype 1:
Motors previously covered under EPAct 1996 will now be required to meet NEMA Premium® Efficient levels (NEMA MG1 Table 12-12):
- General Purpose 3 Phase Motors
- 1 to 200 HP
- NEMA frame 143T and larger
- C-Face Motors with Base Mount
Subtype 2:
3 Phase motors not covered under EPAct 1996 and meeting the following requirements will now be required to meet old EPAct 1996 minimum efficiency standards (NEMA MG1 Table 12-11):
- General Purpose and Definite Purpose 3 Phase Motors
- 1 to 200 HP
- NEMA frame 143T and larger
- U-Frame Motor Designs
- NEMA Design C Torque
- Close Coupled Pump
- Metric IEC
- Fire Pump
- Footless Design, C-Face Without Base
- Vertical Solid Shaft Normal Thrust
- 8-Pole General Purpose NEMA Frame
- 3 Phase General Purpose Design up to 600 Volts
- NEMA Design B General Purpose 201 to 500 HP
