摘　　要：IPMSM的转矩脉动作为一项重要的性能指标,直接影响电机的控制精度和稳定运行,因此对IPMSM的转矩脉动优化设计至关重要。田口法是一种简单、有效的多目标优化方法,同时磁极偏移可以有效削弱电机的齿槽转矩以及降低转矩脉动,结合这两种方法本文提出了应用田口法+磁极偏移对IPMSM的转矩脉动进行优化设计。通过对比分析了未优化、磁极偏移优化和田口法+磁极偏移优化3种设计方案的仿真结果,验证了田口法+磁极偏移优化设计方案的转矩脉动优化效果为最佳。The torque ripple of IPMSM is an important performance index, which directly affects the control precision and stable operation of the motor. Therefore, the torque ripple optimization design of IPMSM is very important. The Taguchi method is a simple and effective multi-objective optimization method. At the same time, the magnet shifting can effectively weaken the cogging torque and reduce the torque ripple. Combining these two methods, this paper proposed to optimize the torque ripple of IPMSM by Taguchi method and magnet shifting. By comparing the simulation results of the three design schemes, such as un-optimized, magnet shifting optimization and Taguchi method + magnet shifting optimization, it is proved that the optimal design scheme of the Taguchi method + magnet shifting optimization has the best effect of torque ripple optimization.
