A magnetic suspension motor with high reliability vibration compensation

Abstract

The invention discloses a magnetic suspension motor with high reliability vibration compensation, including a motor body, First leg, Heat dissipation rib, second leg, bearing cap, end cap, Position sensor, impeller, rotor, demarcation line, limit ring, mounting shaft, axial cushioning mechanism, Iron core, impeller blade, electrostatic precipitator, Filter screen and seal cover, the bottom side ofthe motor main body is provided with a first leg, one side of the first leg is provided with a second leg, one side of the motor main body is provided with a rotor sleeve, the other side of the motormain body is provided with an end cover. The side end of the rotor sleeve is provided with a finite position ring, the middle part of the limit ring is provided with a position sensor, and one side of the position sensor is provided with a rotor. Under the high-speed operation, the phenomenon of the rotor jumping can be eliminated by using an axial cushioning mechanism, and the axial force of therotor can be counteracted, so that the movement of the rotor is stable, and the labor intensity of the working personnel is reduced.

Description

technical field [0001] The invention relates to the field of magnetic levitation motors, in particular to a magnetic levitation motor with high reliability vibration compensation. Background technique: [0002] In mechanical devices, magnetic levitation motors are widely used. Magnetic levitation motors use magnetic bearings instead of traditional bearings, and the motor rotor is suspended without friction. The rotor of the motor adopts permanent magnets. When working at high speed, the eddy current loss of the rotor caused by harmonic current will cause a high temperature rise of the rotor in the high-speed magnetic levitation motor. After the temperature rises, it will seriously affect the running stability of the rotor. If the temperature of the rotor is too high, it will cause irreversible demagnetization of the permanent magnet. However, in the existing magnetic levitation motor, when the rotor speed is too high, it is easy to generate relatively large noise, and the r...

AI Technical Summary

Problems solved by technology

After the temperature rises, it will seriously affect the running stability of the rotor. If the temperature of the rotor is too high, it will cause irreversible demagnetization of the permanent magnet.

However, in the existing magnetic levitation motors, when the rotor speed is too high, it is easy to generate large noise, and the rotor has excessive axial force and mechanical wear, which greatly reduces the reliability of the motor.
