A dual-axis magnetic suspension bearing reluctance motor

Abstract

The invention discloses a dual-shaft magnetic bearing reluctance machine. A penetrating polygonal through hole is formed in a rotor shaft along a central axis, an output shaft is arranged in the polygonal through hole, a polygonal cylinder is arranged at an intermediate segment of the output shaft and is connected with the polygonal through hole in a matching way, a rotor is arranged on the rotorshaft, a stator is arranged on an inner wall of an enclosure and encircles the rotor, a radial magnetic bearing is arranged between the rotor shaft and the enclosure and is used for adjusting a radialposition of the rotor shaft, an axial magnetic bearing is arranged on the enclosure and is used for adjusting the axial positions of the rotor shaft and the output shaft, the axial magnetic bearing comprises two axial magnetic bearing stators, a disc-type first axial magnetic bearing rotor and a disc-type second axial magnetic bearing rotor, and the two axial magnetic bearing stators are fixed onthe enclosure. A mode that the rotor shaft and the output shaft are combined is employed, the dual-shaft magnetic bearing reluctance machine can be maintained without completely disassembling the rotor shaft and the rotor when defects such as shaft head wear or shaft bending occur in the output shaft, and labor and material are saved.

Description

technical field [0001] The invention relates to the field of magnetic levitation motors, in particular to a biaxial magnetic levitation bearing reluctance motor. Background technique [0002] In the study of the support system of the motor rotor shaft, in order to solve the problems of frictional resistance, high noise and high energy consumption in traditional mechanical bearings, magnetic suspension bearings are an ideal choice. Using magnetic suspension bearings to support the rotor shaft can also save a lot of mechanical parts. On the other hand, during the use of the magnetic levitation motor, although the magnetic levitation bearing is not easy to wear with the rotor shaft, there are still defects such as the easy wear of the shaft head of the rotor shaft. When repairing the worn rotor shaft, it is usually necessary to disassemble the rotor shaft and the rotor from the casing simultaneously for maintenance. When repairing the rotor shaft, usually the rotor needs to b...
