This document specifies the energy efficiency grades, energy efficiency limit values, and test methods for three-phase asynchronous motors supplied by the power grid, variable-frequency speed-regulating three-phase asynchronous motors, single-phase asynchronous motors, and motors used for air conditioner fans. This document applies to general-purpose motors or general-purpose explosion-proof motors with rated voltage below 1000V, powered by a 50Hz three-phase AC supply, rated power ranging from 120W to 1000kW, and with 2, 4, 6, or 8 poles, featuring a single-speed enclosed self-fan cooling design, N design, and continuous duty. This document applies to general-purpose motors or general-purpose explosion-proof motors with rated voltage below 1000V, rated speed ranging from 600r/min to 6000r/min, powered by a frequency converter, rated power within the range of 120W to 1000kW, cooling method of IC416, and continuous duty. This document also applies to general-purpose motors such as capacitor-start induction motors (120W~3700W), capacitor-run induction motors (120W~2200W), dual-capacitor induction motors (250W~3700W), as well as capacitor-run motors (10W~1100W) and brushless DC motors (10W~1100W) for air conditioner fans, all operated at voltage of 690V and below with 50Hz AC power supply.
