Abstract: The speed control system of switched reluctance motor (SRM)is suitable for electric bicycles or other low-power devices ,and removable occasions. In this paper, introduced the new design thought and method on the basis of analyzing the characteristics about witched reluctance motor. The method was used to design and trial-produce the speed control system of 250W switched reluctance motor for the car. This system has the fine function, which indicates the correctness (scientificalness) of the method and has a further guiding significance to SRM.
