Product Description
2.2 Energy efficient motors (→ GM)
DT/DV and DTE/DVE four-pole AC motors comply with the energy efficiency standards
and energy efficiency regulations of the following countries:
• USA (EPAct)
• Australia
• New Zealand
• Brazil
• Canada
Europe CEMEP, the association of European electric motor manufacturers, has reached an
agreement with the European Commission’s General Directorate for Energy that all 2
and 4-pole low-voltage AC motors from 1 to 100 kW will be classified on the basis of
their efficiency, and that this classification will be identified on the nameplate and in cat-
alogs. The classification consists of EFF3, EFF2 and EFF1 classes. EFF3 refers to mo-
tors without any particular efficiency requirement. EFF2 indicates improved efficiency
motors and EFF1 is for high-efficiency motors.
Type DT/DV four-pole AC motors of motor sizes 90S to 280M meet the requirements of
efficiency class .
Type DTE/DVE four-pole AC motors of motor sizes 90S to 280M meet the requirements
of efficiency class . These motors are referred to as energy efficient motors.
