A Simplified Design Methodology for Switched Reluctance Motor using Analytical and Finite Element Method

Abstract

Switched reluctance motors (SRM) is gaining wider popularity for variable speed drives. These motors have been developed for electric propulsion, fan, pump and even as starter/alternator for aerospace applications. This paper gives the step-by-step design procedure of a 16/12 switched reluctance motor for a spacecraft actuator. Machine design has been started with analytical method to fix the major parameters and optimization is carried out using finite element technique. Inductance and torque developed has been computed using both the methods and a good comparison seem between them. The motor has been realized and tested for its capability.
