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 and 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.

Summary	This Chinese standard specifies the small power induction motor (hereinafter referred to as the motor) the energy efficiency rating, energy efficiency limit values ??, target energy efficiency limit values ??and test methods for evaluating values ??of energy conservation. This standard applies to 690V and below 50Hz AC power supply voltage and low-power three-phase asynchronous motor (10W ~ 2200W), asynchronous motors (10W ~ 2200W), capacitor start induction motor (120W ~ 3700W), two-value capacitor asynchronous motor (250W ~ 3000W) and other general-purpose motors, as well as room air conditioner fan motor (6W ~ 550W).
