开关磁阻电机（SRM）作为不使用稀土材料的电机而备受关注。是电动汽车应用的候选技术。此外，Axial-Flux结构可以有效利用In-Wheel扁平电机空间。然而，如何确定轴向磁通SRM（AFSRM）的最佳设计尚未确定。本文主要讨论AFSRM的尺寸和重量的减小。首先，使用有限元分析 (FEA) 检查用于增加扭矩体积密度的 SRM 直径和轴向长度的最佳比率（直径/轴向长度）。因此，找到了关于最大扭矩体积密度的直径的最佳定子磁极长度。之后，针对电动汽车设计了双定子AFSRM。
Switched Reluctance Motor (SRM) attracts attention as motor that use no rare earth materials. And it is a candidate technology for electric vehicle application. In addition, Axial-Flux structure has possibility of effective utilization of In-Wheel flat motor space. However, it is not established how to decide optimum design of Axial-Flux SRM (AFSRM). This paper mainly discusses the reduction in size and weight of AFSRM. First, the optimum ratio of SRM's diameter and axial length (diameter/axial length) for increase torque-volume density is examined using FEA. So, the optimum stator pole length regarding to the diameter for maximum torque-volume density is found. After that, a double stator AFSRM is designed for EV.
