摘　　要：永磁电机无传感器启动的难点在于普通三段式启动的方法对于特定参数具有依赖性,所以在参数设定上要求十分精确。本文设计了一个基于反电动势锁相环积分法的永磁同步电机无传感器模型,在三段式启动的基础上可以快速平稳启动,并且本设计所使用的锁相环策略对于电机参数具有一定的自主调整功能,使得电机对于特定参数的依赖性降低,并经过仿真实验证明了相应结论。The difficulty of sensorless startup of permanent magnet motor is that the ordinary three stage method is dependent on the specific parameters, so it is very accurate in the parameter setting. In this paper, a sensorless model of permanent magnet synchronous motor （PMSM） based on the inverse EMF phase-locked loop integral method is designed, which can be started quickly and steadily on the basis of the three-stage startup. And the phase-locked loop strategy used in this design has a certain independent adjustment function to the motor parameters, so that the dependence of the motor on the specific parameters is reduced. The simulation results prove the corresponding conclusion. Key Word： PMSM; Back EMF; PLL
