Abstract

The invention relates to a switched reluctance motor with a dual-rotor structure, and belongs to the technical field of switched reluctance motors. The switched reluctance motor with the dual-rotor structure comprises a left end cover, a right end cover, an enclosure, a stator core, an inner-layer winding, an outer-layer winding, an outer rotor core, an inner rotor core, a bearing A, a bearing B, a main shaft and a flange. A group consisting of the outer rotor core, outer-layer salient poles of a stator and windings of the outer-layer salient poles of the stator, and a group consisting of the inner rotor core, inner-layer salient poles of the rotor and windings of the inner-layer salient poles of the stator simultaneously work equivalent to an outer-rotor switched reluctance motor and an ordinary switched reluctance motor respectively, and the torque of two rotors is superposed to obtain output torque; and by the structure, the space of the motor is fully utilized, and compared with that of the conventional switched reluctance motor with the same rotating speed and the same volume, power density is greatly increased.

Description

technical field [0001] The invention relates to a switched reluctance motor with a double-rotor structure, belonging to the technical field of switched reluctance motors. Background technique [0002] The switched reluctance motor is a motor with 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 concentrated winding; It 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 density, high efficiency, large starting torque, small starting current, strong overload capacity, and can start with heavy loads. Its high...
