This standard specifies the energy efficiency grade, energy efficiency limit value, target energy efficiency limit value, energy saving evaluation value and test method of small power asynchronous motors. This standard applies to low-power three-phase asynchronous motors (10W-2200W), capacitor-run asynchronous motors (10W-2200W), capacitor-start asynchronous motors (120W-3700W) and double-value capacitors powered by 690V and below and 50Hz AC power supply. General-purpose motors such as asynchronous motors (250W-3000W), and room air conditioner fan motors (6W-550W).
