Title:
THREE-DEGREE-OF-FREEDOM BEARINGLESS ASYNCHRONOUS MOTOR EXCITED BY CONSTANT CURRENT SOURCE
Document Type and Number:
WIPO Patent Application WO/2020/001290
Kind Code:
A1
Abstract:
Disclosed in the present invention is a three-degree-of-freedom bearingless asynchronous motor excited by a constant current source, comprising a rotor and a stator, the rotor consists of a rotation shaft and a rotor iron core, and an even number of rotor windings or conducting bars are uniformly provided on the outer circumference of the rotor iron core. The stator comprises a stator iron core, a magnetic isolation ring, axial suspension windings, and a magnetic conduction ring which are sequentially connected radially outwards along the rotor iron core, and axial control iron cores and circular ring-shaped constant current source windings symmetrically provided at two sides of the stator iron core; and the outer edges of the axial control iron cores are connected to the magnetic conduction ring, and the inner edges of the axial control iron cores extend towards the rotor iron core. The stator iron core and the magnetic isolation ring are each a T-shaped structure consisting of an axial portion and a radial portion having an outer end connected to the inner wall of the axial portion; the outer wall of the axial portion of the stator iron core fits the inner wall of the axial portion of the magnetic isolation ring; and the radial portion of the magnetic isolation ring divides the axial portion and the radial portion of the stator iron core into two symmetrical portions. Motor torque windings and radial suspension windings are wound around the stator iron core.
