本文提出了一种电动汽车用开关磁阻电机（SRM）的多目标优化设计方法。电动汽车用电机需要具有高转矩、高效率和高转矩密度。因此，通过使用三个权重因子和三个基准值，将所构建的优化函数选定为最大平均转矩、单位铜耗最大平均转矩以及单位电机叠片体积最大平均转矩之间的合理折衷。定子和转子极弧角被选作优化变量。此外，作者还讨论了优化设计的设计要求和一些约束条件。优化设计结果表明，所提出的方法很好地满足了电动汽车对电机的要求。已经制造出了一款电动汽车用优化设计的轮毂式开关磁阻电机样机。本文为实现电动汽车用开关磁阻电机的优化设计提供了一种有价值的方法。
The method of the optimization design with multi-objectives for switched reluctance motors (SRMs) in electric vehicles (EVs) is proposed in this paper. It is desired that electric motors for EVs have high torque, high efficiency, and high torque density. Thus, the developed optimization function is selected as the correct compromise between the maximum average torque, maximum average torque per copper loss, and maximum average torque per motor lamination volume, by using three weight factors and three base values. The stator and rotor pole arc angles are selected as the optimized variables. Furthermore, the authors also discuss the design requirements and some constraints on the optimization design. The results of the optimization design show that the proposed method meets the requirements of EVs on electric motors well. A prototype of the optimally designed in-wheel SRM for EVs has been manufactured. This paper provides a valuable method to implement the optimal design of SRMs for EVs.
