Abstract

Analysis of electrical machines based on finite element method (FEM) has found widespread acceptance in handling the complexity introduced by deeply saturated, doubly salient iron structure and nonlinear properties of magnetic circuit, which are the unique characteristics of a switched reluctance motor (SRM). This paper presents an FEM based analysis to accomplish optimum geometry of SRM. The sensitivity analysis of SR motor geometry is carried out for stator- and rotor pole-arc/pole-pitch ratio, and radial air gap length as motor design variables. The optimum value of design variables are arrived at by choosing their values for maximum value of average torque developed by the motor
