Problems solved by technology

In the development process of switched reluctance motor, the mold is the main cost. If the stator core can be disassembled into modules, the mold cost can be reduced. The existing design theory of switched reluctance motor can support the stator core to be disassembled into modules. However, it can only be disassembled into a si

Embodiment Construction

[0035] In order to reduce the phase-to-phase mutual inductance of the reluctance motor, the present invention provides a single-phase multi-pole module combined switched reluctance motor, wherein the single-phase multi-pole module used is such as figure 1 As shown, the single-phase multi-pole module 10 integrates a core module 11 and a single-phase winding 12. The core module 11 is a segmented module of the stator core. The core module 11 includes a salient pole and a yoke connecting the salient poles. The number of salient poles of the iron core module 11 is z, z≥2 and is a natural number, and the figure shows the case where the number of salient poles is 2; the angles between adjacent salient poles of the iron core module are all A; the single-phase winding Wrapped on the salient pole or yoke of the iron core module. The single-phase multi-pole modular combined switched reluctance motor of the present invention includes a rotor iron core, a motor casing, and a motor shaft, ...

Abstract

The invention discloses a single-phase multi-polar module and a single-phase multi-polar module combined switch reluctance motor, and belongs to the field of switch reluctance motors. The motor comprises a rotor core (20), a motor casing (30), a motor shaft (40) and a plurality of single-phase multi-polar modules (10). Due to the fact that the reluctance motor is combined and formed by adopting the single-phase multi-polar modules (10), salient pole staggering or a shared yoke magnetic path does not exist among phases, only respective salient pole magnetic path of each phase is used in the working process, so that interphase mutual inductance can be reduced, meanwhile the die cost can be obviously reduced by adopting the single-phase multi-polar modules compared with an integral core, and the problems of interphase mutual inductance and die cost are solved.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of switched reluctance motors, in particular to single-phase multi-pole modules and single-phase multi-stage module combined switched reluctance motors. [0003] 【Background technique】 [0004] In the existing switched reluctance motor, the salient poles of each phase are arranged in a staggered manner, and the yoke is a common magnetic circuit. When a single phase is energized, the mutual inductance between phases is relatively weak. At this time, the flux linkage is relatively simple, and the control calculation is relatively easy. When the two phases have overlapping working areas, the two phases need to share the yoke magnetic circuit and use the salient pole magnetic circuit interchangeably. At this time, a relatively serious mutual inductance between phases occurs, which makes the magnetic field extremely complicated and difficult to calculate accurately, which in turn leads to complex control strategies....
