以高精度直线电机为研究对象，提出一种直线电机推力波动补偿的方法。通过解析法分析，归纳了直线电机磁阻力的一般规律，合理设置补偿器参数，进而为抑制直线电机的推力波动提供了理论依据。最后以一台6槽8极电机为例，进行了有限元分析与试验验证，结果均表明补偿器对磁阻力补偿效果达到60%以上。

Taking the high precision linear motor as the research objecta method for thrust ripple compensation of linear motor is proposed. The general law of detent force of linear motor is analyzed and summarized by analytical methodwhich provides a theoretical basis for rationally setting compensator parameters and suppressing linear motor thrust ripple. Finallythe finite element analysis and experiment of 6-slot 8-pole motor is carried out. The results show that the compensation effect of the compensator on the detent force is over 60%.
