Abstract

Electromagnetic characteristics are critical for performance evaluation of switched reluctance machine (SRM), but it´s very difficult to get them due to strong nonlinearity and coupling. In this paper, the detailed magnetization and torque characteristics of SRM are obtained by finite element method (FEM) firstly, and then an analytic method (AM) is presented to calculate the characteristics. The rotation range of the rotor is divided into five different regions, and the magnetic equivalent circuit for each region is built. The detailed calculation processes of some key parameters are given as well. The results from FEM and AM are compared to verify the accuracy of AM. Finally, the simulation model of the SRM based on support vector machine (SVM) is built to display the application of electromagnetic characteristics.
