This standard specifies the energy efficiency grades,minimum allowable values of energy efficiency and testing methods of three-phase asynchronous motors,single-phase asynchronous motors and air conditioner fan motors.
This standard is applicable to general motors and general explosion-proof motors of which the power is supplied by 50 Hz three-phase AC power supply,with the rated voltage of less than 1 000 V,the rated power ranging from 120 W to 1 000 kW,2,4,6 or 8 poles,single-speed enclosed fan-cooled type,N design and continuous duty. This standard is also applicable to the general motors (e.g. capacitor-start asynchronous motors (120 W~3 700 W),capacitor-run asynchronous motors (120 W~2 200 W) and two-value capacitor asynchronous motors (250 W~3 700 W)) supplied by 50 Hz AC power supply with the voltage of≤690 V,and the capacitor-run asynchronous motors (10 W~1 100 W) and brushless DC motors (10 W~1 100 W) for air conditioner fans.
