A reluctance motor with mutually canceling edge effects

Abstract

The invention provides a reluctance motor capable of offsetting a fringe effect. The reluctance motor comprises a shell, exciting windings, stator cores, a rotor core, A-phase armature windings, B-phase armature windings, C-phase armature windings and a shaft. The quantity of the stator cores is 6X, two protruding stator poles are arranged on the inner side of each stator core, 5.5X protruding rotor poles are arranged on the rotor core, X is an even number, the armature windings are wound on the stator poles on the side, in the clockwise direction, of the stator cores, the winding directions of the armature windings on the adjacent stator cores are opposite, the exciting windings are wound on the stator poles on the side, in the anticlockwise direction, of the stator cores, the winding directions of all the exciting windings are the same, and the armature windings and the exciting windings are all integrated windings. A stator of the reluctance motor capable of offsetting a fringe effect provided by the invention consists of 6X independent stator cores, and the winding directions of the armature windings on the adjacent stator cores are opposite, so that the reluctance motor has the excellent characteristics such as high fault-tolerant operating capability, higher energy density and high-temperature high-speed operating capability.

Description

technical field [0001] The invention relates to a reluctance motor with mutually offsetting edge effects, which belongs to the field of special motors. Background technique [0002] In many fields of motor drive and speed regulation, the requirements for accuracy are not very strict, and the requirements for motors are more simple in structure, high in reliability, low in cost and easy to maintain, etc., so reluctance type motors become an ideal choice. The rotor of the reluctance motor is made of laminated silicon steel sheets. It has no permanent magnet and no winding structure. It has high rigidity and is easy to dissipate heat and cool. It can run at high speed and can adapt to relatively harsh working environments. At the same time, the weight of the rotor is relatively light. It can effectively improve the response speed and robustness of the whole system. [0003] At present, permanent magnet reluctance motors are widely used because of their advantages of high effic...
