Title:
THREE-DEGREE-OF-FREEDOM BEARINGLESS SWITCH RELUCTANCE MOTOR EXCITED BY CONSTANT CURRENT SOURCE
Document Type and Number:
WIPO Patent Application WO/2020/001289
Kind Code:
A1
Abstract:
The present invention discloses a three-degree-of-freedom bearingless switch reluctance motor excited by a constant current source, comprising a rotor and a stator, wherein the rotor comprises a rotary shaft and a rotor core, and a plurality of rotor teeth are uniformly arranged on the outer circumference of the rotor core; the stator comprises a stator core, a magnetic isolation ring, an axial suspension winding and a guide magnetic ring, which are sequentially connected with each other, as well as an axial control core and a circular constant current source winding symmetrically arranged on both sides of the stator core, wherein the outer edge of the axial control core is connected with the guide magnetic ring, and the inner edge thereof extends toward the rotor core; the stator core and the magnetic isolation ring is both composed of an axial part and a radial part, wherein the outer end of the radial part is connected with the inner wall of the axial part, the outer wall of the axial part of the stator core is attached to the inner wall of the axial part of the magnetic isolation ring, and the radial part of the magnetic isolation ring isolates the axial part of the stator core from the radial part of the stator core; a plurality of suspension teeth and torque teeth are arranged on the inner circumference of the radial part of the stator core, wherein a radial suspension wind and a torque winding are respectively wound on the suspension teeth and the torque teeth.
