Abstract

The invention discloses an axial magnetic circuit reluctance-type multipolar resolver adopting a rotor with a sinusoidal half-wave structure. The resolver comprises a stator, the rotor, a first coil A-X and a second coil B-Y, wherein the rotor is manufactured by adopting a non-magnetic conduction support material; and a plurality of pairs of magnetic-conductive sinusoidal half-wave bands serving as polar magnetic circuits are uniformly arranged on the inner and outer surfaces of the non-magnetic conduction support material along the circumferential direction of the non-magnetic conduction support material. Compared with a reluctance-type resolver adopting a rotor with full-wave sinusoidal magnetic-conductive bands, the axial magnetic circuit reluctance-type multipolar resolver adopting therotor with the sinusoidal half-wave structure, which is disclosed by the invention, has the advantages that the magnetic-conductive bands of the rotor are of a sawtooth shape; and the rotor adopts the half sinusoidal wave magnetic-conductive bands as a pair of pole magnetic circuits, so that the rotor space can be saved for the multipolar reluctance-type resolver and more rotor magnetic poles canbe accommodated in limited space.

Description

technical field [0001] The invention belongs to the technical field of rotary transformers, and relates to an axial magnetic circuit reluctance rotary transformer adopting a rotor sinusoidal half waveguide tape magnetic circuit structure. Background technique [0002] The rotor structure of the existing axial magnetic circuit reluctance resolver transformer is a full-wave sinusoidal structure, which leads to an excessively large rotor volume and affects the geometric space occupied by the entire resolver. Contents of the invention [0003] In order to solve the problems of complex structure of the existing axial magnetic circuit sine full wave axial magnetic circuit reluctance rotary transformer, the present invention provides a rotor sine half wave axial magnetic circuit reluctance multi-pole rotary transformer. The transformer can save the space of the resolver with the same number of pole pairs. [0004] The purpose of the present invention is achieved through the foll...
