Minimum allowable values of energy efficiency and

values of efficiency grade for small-power motors

1 Scope

This standard specifies energy efficiency grade, minimum allowable values of energy

efficiency, target minimum allowable values of energy efficiency, evaluating values of

energy conservation, and test method for small-power asynchronous motors (hereinafter

referred to as "motor").

This standard is applicable to general purpose motors - small-power 3-phase

asynchronous motor (10 W to 2200 W) powered by 50 Hz & 690 VAC and below voltage;

capacitor running asynchronous motor (10 W to 2200 W); capacitor starting asynchronous

motor (120 W to 3700 W), double-value capacitor asynchronous motor (250 W to 3000 W);

and motor (6 W to 550 W) for air conditioning fan in room etc.
