In this paper, the authors present the performance of a 6/4-pole configuration Switched Reluctance Motor (SRM) drive with fixed turn-off angle control scheme. Turn-off and on angles (dwell angle) plays an important role in developing electromagnetic torque in SRM and leads to stable or unstable operation of the drive. However, this paper analyze the effect of decreased decay time for form of wave current by adding resistance in the return path, so that give the user a flexibility to tuning the overlap angle (on and off angles) without developing negative torque, finally lead to reduce the torque ripple.
