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 dual stator and rotor switched reluctance motor. Background technique [0002] The switched reluctance motor is a double salient pole structure motor. The salient poles of the stator and rotor are laminated by ordinary silicon steel sheets. The rotor has neither windings nor permanent magnets, and concentrated windings are wound on the stator poles; The number can be divided into single-phase, two-phase, three-phase, four-phase and multi-phase switched reluctance motors, of which three-phase 6 / 4 structure and four-phase 8 / 6 structure are the majority. The switched reluctance motor has the advantages of simple structure, easy manufacturing, reliable operation, not easy to damage, easy to adjust speed, high power factor, high efficiency, large starting torque, small starting current, strong overload capacity, and heavy load starting. Its high-speed constant power zone has wide range and good pe...
