Abstract

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.
