摘要定位力矩是永磁同步电机固有的问题,对驱动系统将产生不利的影响。在永磁同步电机齿槽定位力矩特点分析的基础上,提出一种在电流中注入谐波对定位力矩进行补偿的方法,抑制了由于定位力矩引起的速度波动,从而减小了对电机低速性能的影响。仿真和实验结果验证了该方法的有效性。 The cogging torque of permanent magnet synchronous motor is harmful to driving systems. In this paper, a compensation method based on the harmonic current injection is presented to reduce the influence of cogging torque on the motors. Simulation and experimental results show that the presented method is effective to compensate the cogging torque.
