The invention provides a magnetic bearing, a supporting device and a motor assembly, wherein the magnetic bearing is used for supporting and limiting a shaft. The magnetic bearing comprises a rotor core and a stator core, wherein the rotor core sleeves the shaft, and a rotor permanent magnet is mounted outside the rotor core; the stator core sleeves the outside of the rotor core, a plurality of stator windings corresponding to the rotor permanent magnet are arranged on an inner annular surface, facing the stator core, of the stator core, and the stator windings and an electromagnetic force is formed by the rotor permanent magnet, so that the rotor core is maintained suspended. The magnetic bearing, the supporting device and the motor assembly provided by the invention effectively solve the problem that in the prior art, a phenomenon that the temperature of the bearing is high, the temperature rise speed of the bearing is fast, the rotating speed of the bearing cannot meet the requirements and the noise of the bearing is big likely occurs.
Description
technical field [0001] The invention relates to the technical field of bearings, in particular to a magnetic suspension bearing, a support device and a motor assembly. Background technique [0002] In the prior art, mechanical bearings are generally used on the output shaft of the motor. Driven by the high-speed rotating output shaft, this kind of bearing is likely to cause high temperature, fast temperature rise, low speed, and high noise. . Contents of the invention [0003] Embodiments of the present invention provide a magnetic suspension bearing, a support device and a motor assembly to solve the problems in the prior art that the bearing is prone to high temperature, rapid temperature rise, insufficient rotational speed and high noise. [0004] In order to solve the above technical problems, the present invention provides a magnetic suspension bearing, which is used to support and limit the shaft, which is characterized in that it includes: a rotor core, which is sl...
