Research on optimal starting condition of switched reluctance motor

This paper studied the optimal starting condition of switched reluctance motor (SRM). At first, this paper established a nonlinear dynamic model of SRM and simulated SRM's dynamic performance. The dynamic model and the simulation results were tested and verified by comparing the simulated results with the experiment results. On the basis of these, this paper analyzed the condition of one-phase starting and two-phase starting of SRM, proposed an optimal change curve of turn-off angle, and the parameters of the curve were obtained with simulation results. By use of this curve, SRM can get the largest starting torque, the largest load start ability, the shortest starting time, and the smallest torque pulsation during the whole start period.
