振动和噪声是开关磁阻电机在变速驱动市场上无法被接受的重要原因。优化电机的物理结构和选择合适的控制策略是降低噪声的两种常用方法。本文提出了一种将这两种优化方法联合收割机结合起来的新方法：开关磁阻电机谐波优化。特别是物理设计主要针对电机的背铁厚度和气隙长度。控制优化是对功率因数影响较大的控制方式和开关角的优化。在相同库珀损的基础上，进行了数学分析和有限元模拟。最佳的控制策略和相应的打开和关断角计算参考一个合适的电机尺寸。仿真结果表明，谐波优化可以在不增加功率损耗的情况下，很大程度上降低电机的振动和转矩涟漪。
Vibration and acoustic noise are the important reasons for switched reluctance motor to be unacceptable in variable speed drive market. To optimize the physical structure of the motor and to choose the appropriate control strategies are the two conventional ways to reduce the noise. In this paper, a new method is proposed to combine these two optimization ways together: harmony optimization of switched reluctance motor. Especially, the physical design is mainly aiming at the back iron thickness and the air gap length of the motor. Control optimization is about the control mode and turn-on, the turn-off angle which affect the power factor strongly. Based on the same cooper losses, the mathematics analysis and finite element simulation are carried out. The best control strategy and corresponding turn-on and turn-off angles are calculated with reference to a suitable motor dimension. The simulations show that the harmony optimization will reduce the vibration and torque ripple in a large extent without extra power losses.
