Abstract: Switched reluctance motor adopts nonlinearity circuit and nonlinearity control strategies,so analysis of starting performance and study on the corresponding control strategies are becoming more and more important.In this paper,teok a three-phase 6/4 structure switched reluctance motor as object of study.The working principle of this switched reluctance motor were introduced,and the mathematics models under the starting operating state were established.Then briefly described the variable speed control methods.At last,the operating characteristic of this switched reluctance motor under low speed,moderate speed and high speed state were analyzed on simulation,and the corresponding control strategies of each operating state were confirmed. Key Words: Switched reluctance motor;Working principle;Mathematics model;Characteristic analysis;Control strategies
