Abstract

The invention discloses a rotor linear half-wave axial magnetic circuit reluctance multi-pole rotary transformer which comprises a stator, a rotor, a first coil A-X and a second coil B-Y. The rotor ismade of a non-magnetically-conductive supporting material, and multiple pairs of magnetic conductive material linear half-wave bands as polar magnetic circuits are uniformly arranged in the circumferential directions of inner and outer surfaces of the non-magnetically-conductive supporting material. A rotor sinusoidal half-wave axial magnetic reluctance rotary transformer of the invention is a multi-pole reluctance rotary transformer with a rotor magnetically-conductive band in the shape of sawteeth, compared with a full-wave sinusoidal rotor magnetically-conductive band reluctance rotary transformer, a half of linear waveguide tape is used as a pair of pole magnetic circuits in the rotor, in this way, the rotor space can be saved for a multiple-pole reluctance rotary transformer, and more pole rotor magnetic poles can be placed in a 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 linear 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 the existing axial magnetic line linear full-wave axial magnetic circuit reluctance rotary transformer with complex structure and the like, the present invention provides a rotor linear 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 thro...
