This standard specifies the values of efficiency grade, minimum allowable values of energy efficiency, target minimum allowable values of energy efficiency, evaluating values of energy conservation and the test methods for small-power asynchronous motors (hereinafter referred to as "motor").
This standard is applicable to general purpose motors of voltage up to and including 690V and powered by 50Hz AC power source, e.g. small power three-phase asynchronous motor (10W~2200W), capacitor-run asynchronous motor (10W~2200W), capacitor-start asynchronous motors (120W~3700W), two-value capacitor asynchronous motor (250W~3000W), and to the fan motors (6W~550W) of room air conditioner.
