【Abstract】 In recent years, permanent magnet synchronous motor(PMSM) with its low loss, high efficiency, light weight, small noise, wide speed range and other characteristics are widely applied in the new energy vehicles, machinery industry and so on. Especially in some motor design and control system applications, are inseparable from the precise motor parameters. In all those parameters, the inductance parameter is the key technical indicators that affect the motor performance, it’s a essential factor of direct torque control and weak magnetic speed in such dynamic and static experiments. Therefore, this paper mainly studies the method of measuring the inductance parameters of permanent magnet synchronous motor under different strategies, and analyzes the advantages and disadvantages of various methods synthetically.更多还原
