Double-equal pole double-section stator/rotor reluctance generator

Abstract

The invention relates to a double-equal pole double-section stator / rotor reluctance generator, comprising two sections of stators and rotors of a salient pole structure or a non-salient-pole structure formed by laminating silicon-steel plates. A stator salient pole is provided with armature concentrated windings or layer windings; the windings are connected in series or in parallel according to the N-N polarity of the armature windings to form a phase, and the windings are connected in series or in parallel according to the S-S polarity of the armature windings to form the other phase; the rotors are equipped with rotating magnetic poles with the same pole number with the stators, and the adjacent pole windings of the rotors are connected in series or in parallel to form a plurality of N and S groups; the rotors can adopt excitation magnetic poles and permanent magnetic poles in different forms and permanent magnetic and electro-magnetic mixed poles, and a rotor excitation device is arranged on a motor shaft; each rotor can be divided into an inner rotor and an outer rotor; and the armature windings can be arranged on the stators or the rotors. In the invention, by adopting an equal-pole-number stator / rotor technology and series / parallel connection dynamic combination of the windings, output voltage can be regulated conveniently, the utilization ratio of the windings is improved, and power density and efficiency of the generator are enhanced.

Description

technical field [0001] The invention belongs to the technical field of generators, and relates to a reluctance generator, in particular to a biequal pole and double-stage stator-rotor reluctance generator. Background technique [0002] The existing switched reluctance motor (SRM) is a motor with a double salient pole structure. Its stator and rotor are laminated with ordinary silicon steel sheets to form a salient pole type. Concentrated windings are wound on the stator poles, while the rotor has no windings. There is also no permanent magnet; the motor can be divided into single-phase, two-phase, three-phase, four-phase and multi-phase switched reluctance motors according to the number of phases, and also has three-phase 6 / 4 pole structure, 12 / 8 pole structure and four-phase Most of them have 8 / 6 pole structure; the advantages of switched reluctance motor are: simple structure, easy to manufacture, high operating efficiency, high power factor, small starting current, large ...

Problems solved by technology

However, the effect is not so perfect when the power is medium, the number of poles is small, and the operation is at low speed. Especially after the stator and rotor equipolar technology is adopted to improve the power output, the magnetic poles of the stator and rotor equipolar technology are equivalent to the stator and rotor N, S, N , The S magnetic circuit is in the closed state of the static magnetic poles, so the static resistance is particularly large, resulting in large starting resistance of power generation, large energy consumption at low speed, large noise at low speed, small noise at high speed, large vibration at low speed, and small vibration at high speed
