Abstract

The invention provides a magnetic suspension bearing assembly, a motor and a compressor. The magnetic suspension bearing assembly comprises a shell; a permanent magnet assembly is arranged in the shell; a first stator assembly is arranged in the shell and located on the first side of the permanent magnet assembly; a second stator assembly is arranged in the shell and located on the second side ofthe permanent magnet assembly, and the second stator assembly and the first stator assembly are oppositely arranged; a rotating shaft is sequentially arranged in the first stator assembly, the permanent magnet assembly and the second stator assembly in a penetrating manner; and the permanent magnet assembly generates a bias magnetic field, a control magnetic field controls the rotating shaft to dotranslational motion along the Y axis, rotate around the Y axis, do translational motion along the X axis, rotate around the X axis and / or do translational motion along the Z axis by adjusting the bias magnetic field, the X axis and the Y axis are in the radial direction of the rotating shaft, and the Z axis is the axis direction of the rotating shaft. The magnetic suspension bearing assembly adopting the structures is compact in structure, capable of effectively shortening the axial length of magnetic suspension, simple in structure and good in stability.

Description

technical field [0001] The invention relates to the technical field of magnetic suspension bearing equipment, in particular to a magnetic suspension bearing assembly, a motor and a compressor. Background technique [0002] Magnetic suspension bearings have a series of excellent qualities such as no contact, no wear, high speed, high precision, no need for lubrication and sealing, and are a high-tech product integrating electromagnetics, electronic technology, control engineering, signal processing, and mechanics. [0003] Magnetic bearings are divided into three types: active, passive, and hybrid. Active magnetic bearings have high rigidity and can be precisely controlled, but require a large volume and power consumption to generate unit bearing capacity. Passive magnetic bearings use the attraction or repulsion between magnetic materials to achieve the suspension of the rotor, and the stiffness and damping are relatively low. The hybrid magnetic bearing uses a permanent ma...
