Abstract

One solution to the high torque ripple problem of the switched reluctance motor is to modify its pole geometry. To show how much this solution is effective, static field analyses are usually contended with. However, dynamic analyses of SRM are to be made to get a real model of SRM. In this study, dynamic analysis of conventional SRM and the modified SRM are made and their performance parameters are compared with each other. The comparison shows an improvement of 23.6 % in torque ripple and 18 % in efficiency which is in agreement with the results of static analysis
