Motors are widely used in various fields of social production and life such as industry, agriculture and transportation. The popularization and application of high-efficiency motors will greatly improve the efficiency of power utilization in the whole society. We analyze the energy efficiency evaluation system of motor system based on the principle of analytic hierarchy process (AHP) and select 20 typical enterprises to evaluate the energy efficiency of the motor systems. It is found that there is still much improvement room in the current energy efficiency level of motors, and high-efficiency motors should be widely promoted. Based on this, the promotion measures of high-efficiency motors are proposed, which can effectively promote the popularization and application of high-efficiency motors.
