Simple and low-cost construction makes switched reluctance motor have great potential of replacing the motor employed in electric driving system. By analyzing the structure and operating principle,the rotational speed response and torque response of switched reluctance motor were simulated in Simulink. Through static and dynamic experiment to a 15 k W motor on a measurement bench,the characteristics curve and efficiency are achieved. The result of simulation and experiment indicate that the motor’s response performance to rotational speed and torque is excellent,and the efficiency is up to 88%,also the motor has large torque ripples under slow-speed rotational speed. The simulation model truly reflects the motor system,and has a certain practical guiding significance
