摘要

本文介绍了采用电机效率和电机重量两个目标函数的内嵌式永磁同步电机的优化设计。采用多目标优化技术对该问题进行求解。提出了一种利用改进遗传算法确定非劣集和最佳妥协解的优化设计方法。为了更准确地预测电机的性能,推导了考虑电枢反应磁通f和磁体磁通变化的铁芯损耗公式。

Multiobjective optimal design of interior permanent magnet synchronous motors considering improved core loss formula
This paper describes the optimal design of interior permanent magnet synchronous motors for which two objective functions regarding motor efficiency and weight are used. Multiobjective optimization technique is applied to finding the optimal solution in this case. An optimal design method that determines both the noninferior set and the best compromise solution employing a modified genetic algorithm is proposed. In order to predict the motor performance more accurately, a core loss formula is derived considering the flux variation due to the armature reaction MMF as well as that due to the magnet.
