A simple magnetic equivalent circuit model for switched reluctance machine

Abstract

In the present paper, a simple model based on magnetic equivalent circuit (MEC) method is introduced for the switched reluctance machine to predict the phase flux linkage characteristic. All equations required to build up the model are given, and therefore, someone can use it easily for different types of the switched reluctance machines. Because of large speed of the suggested model, it can be utilized properly for quick prediction of machine performance. The suggested MEC model is applied to a typical 8/6 switched reluctance motor (SRM), and simulation results including flux linked by a phase, phase current and instantaneous torque are presented. In order to validate the suggested MEC model, the obtained simulation results are compared to those derived from finite element method (FEM) and experimental results.
