Asymmetric double-stator hybrid excitation type axial magnetic field flux switching motor

Abstract

The invention provides an asymmetric double-stator hybrid excitation type axial magnetic field flux switching motor. The asymmetric double-stator hybrid excitation type axial magnetic field flux switching motor comprises a first stator, a second stator and a rotor which are coaxially mounted, the first stator comprises a plurality of magnetic conductive iron cores and permanent magnets which are alternately arranged, each magnetic conductive iron core comprises two stator teeth a and a stator yoke part connected with the stator teeth a, parallel grooves a are formed between the two stator teeth a, and armature windings are wound between the adjacent stator teeth a of the adjacent magnetic conductive iron cores; the second stator is provided with a plurality of T-shaped grooves, the T-shaped grooves divide the second stator into a plurality of stator teeth b of a double-tooth structure, parallel grooves b are formed between double teeth of the stator teeth b, and the adjacent teeth of the adjacent stator teeth b are wound with armature windings and exciting windings at the roots of the stator teeth b; the rotor is arranged between the two stators, an air gap is reserved between therotor and the two stators, the rotor comprises a non-magnetic-conductive ring and a plurality of rotor teeth, and the rotor teeth are evenly distributed in the circumferential direction of the non-magnetic-conductive ring.

Description

technical field [0001] The invention relates to a hybrid excitation motor technology, in particular to an asymmetric dual-stator hybrid excitation type axial magnetic flux switching motor. Background technique [0002] The constant magnetic field generated by permanent magnets makes permanent magnet motors have disadvantages such as difficult voltage adjustment and narrow speed regulation range, which limits their popularization and application in constant voltage power generation and other fields. Therefore, how to effectively adjust the air gap magnetic field in permanent magnet motors It has attracted the attention of scholars at home and abroad. [0003] The emergence of hybrid excitation motors can effectively solve the above problems. It not only inherits many advantages of permanent magnet motors such as high power density and high reliability, but also has the advantages of flexible adjustment of the magnetic field of electric excitation motors. It is widely used in ...
