The present invention can reach purpose of high starting torque, low swinging motion and low noise operation.

Description

technical field [0001] The invention relates to the field of motors, in particular to a double-stator-rotor switched reluctance motor. Background technique [0002] The switched reluctance motor is a motor with a double salient pole structure. The salient poles of the stator and rotor are laminated with ordinary silicon steel sheets. The rotor has neither winding nor permanent magnet, and the stator pole is wound with a concentrated winding. The number can be divided into single-phase, two-phase, three-phase, four-phase and multi-phase switched reluctance motors, among which the three-phase 6 / 4 structure and the four-phase 8 / 6 structure are the majority. The switched reluctance motor has the advantages of simple structure, easy manufacture, reliable operation, not easy to damage, easy speed regulation, high power factor, high efficiency, large starting torque, small starting current, strong overload capacity, and can start with heavy loads. Its high-speed constant power ran...
