The stator and rotor pole structure and power inverters have significant influence on electromagnetic torque performances and efficiency performances. Many papers have investigated on those design parameters on motor result. Inductance and flux linkage will be influenced by rotor and stator pole combination and magnetic circuit. In this paper, a SRM 24/16 rotor shoe will improved form conventional SRM with the same outer diameter stator and stack length. The paper will investigate some rotor pole topologies to get reduce harmonic torque ripple. Radial forces of SRM 24/16 with normal and shoe pole have been compared and the shoe pole structure has more advantages.
