Abstract

A novel segment type switched reluctance motor (SRM) as a rare-earth-less motor is proposed. The torque was increased by 40% and the radial force was decreased by 76% compared with the same size usual variable reluctance (VR) type SRM. Increasing the average torque, however, caused increasing torque ripple. In this paper we develop a 4-phase segment type SRM and show that the torque ripple can be decreased well.
