Design Using Finite Element Analysis of Switched Reluctance Motor for Electric Vehicle

Abstract

In this paper, Switched Reluctance Motor (SRM) for electric vehicle (EV) is designed using finite element method (FEM). The static torque of SRM is estimated with the magnetic field analysis. The temperature rise with time of SRM is estimated with the heat transfer analysis. First, the static torque and temperature rise with time of 600W SRM for sample machine are measured in the experiment, and they are compared with the calculated results using FEM under the same conditions. The validity of magnetic field analysis and heat transfer analysis is verified by the comparisons. Then, the 60 [kW] SRM for EV, which has the output characteristics equal to 1500 [cc] gasoline engine, is designed with the magnetic field analysis and heat transfer analysis.
