Investigation of torque development in SRM under single phase excitation

Abstract

This paper presents the results of an investigation of torque development in the air gap of a 6/4 and 8/6 switched reluctance machines (SRM). Due to the force components acting on the rotor enables us to provide more accurate picture of the torque generation and vibration in this family of electric machines. The analysis for the torque is computed by finite element method. The torque optimisation is investigated by changing the pole arc/pole pitch ratio (y) of the stator, rotor and yoke dimensions.
