Abstract

The invention provides a magnetic bearing for a high-speed magnetic suspension motor. The magnetic bearing comprises a bearing sleeve, a magnetic coil and an annular end cover, wherein the bearing sleeve is of an annular structure and comprises an inner ring, an outer ring and an annular groove; the annular groove is formed between the inner ring and the outer ring; the magnetic coil is located inthe annular groove; the annular end cover is fixedly connected with the outer ring; the inner ring serves as the N pole of the magnetic bearing; and the annular end cover serves as the S pole of themagnetic bearing. According to the magnetic bearing, the bearing sleeve and the end cover are used for coating the coil, and paint immersion and encapsulation are carried out around the coil by utilizing insulating paint, so that the insulating ability of the coil is improved; and the coil becomes a whole, so that it is guaranteed that the magnetic field of the coil is stable, the situation that amotor rotor shakes due to the fact that the magnetic field is not stable is avoided, and it is guaranteed that the magnetic suspension motor operates stably and safely in the long term.

Description

technical field [0001] The invention relates to the technical field of magnetic suspension, in particular to a magnetic bearing for a high-speed magnetic suspension motor. Background technique [0002] With the development of science and technology and the demand of production, the magnetic levitation high-speed motor has become one of the research hotspots in the field of international electrotechnical field. Due to the advantages of high energy density, small structure size and high efficiency of magnetic levitation high-speed motors, it has been widely used in industrial fields such as micro gas turbines, high-speed centrifugal compressors, molecular pumps, high-speed machining centers, flywheel energy storage, etc., and its application fields and scope Still expanding. [0003] During the working process of the magnetic levitation motor, the stability of the motor rotor is the key to ensure the smooth and efficient operation of the motor, and the long-term stable operat...
