Abstract
The utility model provides a switched reluctance motor which belongs to the technical field of motors. The utility model solves the problem of lower efficiency of the entire system, which is caused by the condition that the A phase and the C phase of a traditional switched reluctance motor obstructs the running of the switched reluctance motor because of long follow current time. The electric switched reluctance motor comprises a stator and a rotor, wherein a groove of the stator and a salient pole of the stator, which are evenly distributed at intervals, are arranged at the outer annular face of the stator, a groove of the rotor and a salient pole of the rotor, which are evenly distributed at intervals, are arranged at the inner annular face of the rotor, and the difference of the radian of the groove of the rotor and the radian of the salient pole of the stator is smaller than the difference of the radian of the salient pole of the rotor and the radian of the groove of the stator. The switched reluctance motor can reduce the natural follow current time of the A phase and the C phase, can enhance the efficiency of the switched reluctance motor and saves energy resources.
