A variable frequency high voltage asynchronous motor's energy efficiency rating is a key indicator of energy loss during the conversion of electrical energy into mechanical energy. Which corresponds to the international IEC 60034-30 IE (International Efficiency) classification system; ratings range IE4; with efficiency increasing and energy losses decreasing at each successive level.
