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, The SRM 12/10 and 8/6 will be modified from 12/8 with the same outer diameter stator and stack length. The paper figures out some stator and rotor pole arc to get maximum average torque and torque ripple reduction. For commercial switched reluctance motor, control method is single voltage or current pulse in higher speed not chopping current. The DC link voltage of power converter of SRM is limited, it is difficult to achieve constant torque in wider range of speed because the magnetic circuit is saturated condition, and the phase current cannot rise reference value. To improving average torque at high speed, increasing voltage or rotor poles or winding phases are possible for E-bike application.
