Scope

This standard specifies the energy efficiency grades, energy efficiency limit values and test methods of three-phase asynchronous motors, single-phase asynchronous motors, and motors for air conditioner fans. This standard applies to rated voltage below 1000V, 50Hz three-phase AC power supply, rated power in the range of 120W ~ 1000kW, the number of poles is 2 poles, 4 poles, 6 poles and 8 poles, single-speed closed self-fan cooling, N Design, continuous duty general-purpose motors or general-purpose explosion-proof motors. It is also applicable to the capacitor starting asynchronous motor (120 W ~ 3700 W), the capacitor running asynchronous motor (120 W ~ 2200 W), the double value capacitor asynchronous motor (250 W ~ 3700 W), etc. Electric motors for various applications, as well as capacitor run motors (10 W to 1100 W) for air conditioner fans and brushless DC motors for air conditioner fans (10 W to 1100 W).
