Study on Double Salient Electro-Magnetic Motor Speed Control System

The double salient motor is a new kind of AC brushless motor invented in nineties last century. At present, the studies are focused on the double salient permanent magnet motor (DSPM), but the papers on the double salient electro magnetic motor are few. At first, this paper introduces the configuration and the operation principle of a new kind of double salient electro magnetic motor. Secondly, integrating the three phase bridge converter will advance the method of control. Then, the theory and the structure of the system are introduced. Finally an example of the speed control system of a 500 W double salient electro magnetic motor with 12/8 poles is given. Experimental results demonstrate that this system is simple and convenient in control and it has a good performance of steady state and dynamic response.
