Important Facts About WEG Motors
& the Energy Policy Act-EPAct
GENERAL
PURPOSE
The Department of Energy’s Energy Policy Act (EPAct 92) became effective
October 24, 1997. The purpose is conservation, since electric motors represent
a major portion of electrical energy consumption. Also, the adoption of energy
efficiency motors is expected to reduce the need for new power plants.
MOTORS COVERED BY EPAct 92
• 1 to 200 HP
• NEMA Design A or B
• Continuous duty rated
• Squirrel cage induction
• Thermally protected
• 3600, 1800 and 1200 RPM
• 60Hz - 230 and 460 Volts
• Three-phase
IEC
TRU-METRIC™
Finding this definition too loose, the Department of Energy provided in June 20, 1997 a guidance to electric motor
manufacturers in order to help them to identify what motors are considered “general purpose, definite purpose or special
purpose”. The DOE classified the motors into these categories:
CRUSHER® DUTY
• General Purpose (NEMA and IEC)
• NEMA-T Frame
• Explosion Proof
• Foot-mounted
• Ball or Roller Bearings
NEMA PREMIUM
EFFICIENCY
Originally, EPAct covered motors were defined as follows:
Category I – General purpose as defined by EPAct and applicable from October 24, 1997.
Category II – Definite purpose that can be used in most general purpose applications.
Category III, IV and V – Motors not covered by EPAct (definite and special purpose motors).
• Two-speed motors
• Brake motors
• Inverter duty motors
• Single-phase motors
• Fractional horsepower motors
DEFINITE
PURPOSE
• 250HP and up (above EPAct)
• 900RPM and lower
• NEMA Design C or D
• DC motors
• Close-coupled JM, JP and P-Base motors

CONTROLS
Standard Efficiency motors covered by EPAct cannot be sold for application within the United States. These motors,
however, can be purchased for export.

TECHNICAL DATA
• All WEG High Efficiency motors meet EPAct levels.
• WEG’s NEMA Premium Efficiency line exceeds EPAct levels.
• Standard efficiency motors are still available on a custom basis for installation outside the United States.

Warranty Service:
If in the event that a WEG product should require warranty service due to defective materials or workmanship, WEG will,
at it’s option, either repair or replace the defective product. Warranty is applied to products that have been, at all times,
operated or used under the normal operating conditions for which the product was designed and properly maintained.
WEG is not responsible for any expenses incurred in installation, removal from service, transports (freight) or
consequential expenses.
Disclaimer of Expenses:
The Company hereby disclaims all other express or implied warranties, including without limitation all implied warranties
of merchantability pertaining to such products or parts. The foregoing obligation to repair or replace such products or
parts shall be the sole and exclusive remedy of the purchaser, its customers, or users of the products or parts.
Proper Storage of Motors:
When motors are not immediately installed, they should be stored in their normal upright position in a dry even temperature
place, free of dust, gases and corrosive atmosphere. Inactive motors tend to expel grease from between the bearing
surfaces, thereby removing the protective film that impedes metal-to-metal contact. At least once per month shafts
should be rotated in accordance with WEG installation and maintenance manual. Motors stored for a period exceeded
one year should have the bearings re-lubricated in accordance with WEG motor installation and maintenance manual.
