Abstract:The mathematical model of switched reluctance drive was analyzed.Made the coil’s model, relay and power converter in Matlab/Simulink environment. By these blocks made the nonlinear modle of SR-motor，made the low speed heavy load simulation under chopped current control.The results demonstrated the effectiveness of the nonlinear simulation model.The model offer a way for SR-motr control system analysis and the design.
