THREE-DEGREE-OF-FREEDOM BEARINGLESS SWITCH RELUCTANCE MOTOR EXCITED BY CONSTANT CURRENT SOURCE

摘要

A three-degree-of-freedom bearingless switched reluctance motor excited by a constant current source includes a rotor and a stator. The rotor consisting of a rotating shaft and a rotor core, where a plurality of rotor teeth is uniformly distributed on an outer circumference of the rotor core. The stator includes a stator core, a magnetic isolation ring, an axial suspension winding, and a magnetic conduction ring that are sequentially connected, and axial control cores and annular constant current source windings which are symmetrically arranged on both sides of the stator core. Outer edges of the axial control cores are connected to the magnetic conduction ring, and inner edges extend to the rotor core. The stator core and the magnetic isolation ring both consist of an axial part and a radial part of which an outer end is connected to an inner wall of the axial part.
