Document Type and Number:
WIPO Patent Application WO/2019/037523
Kind Code:
A1
Abstract:
The present invention relates to the technical field of vacuum cleaners, and provides a high-speed brushless vacuum cleaner motor using a magnetic bearing and a vacuum cleaner. The vacuum cleaner motor comprises a stator (6) and a rotor (7) rotatably provided in the stator (6). The vacuum cleaner motor is provided with the magnetic bearing capable of suspending the rotor (7) in the stator (6). During operation, the rotor (7) of the vacuum cleaner motor does not in contact with any object. A vacuum cleaner having the vacuum cleaner motor. The vacuum cleaner motor comprises a controller. The controller actively adjusts the speed of the rotor (7) of the vacuum cleaner motor according to the load size in the vacuum cleaner. The vacuum cleaner motor and the vacuum cleaner can overcome the problem that the existing motor is limited by the bearing and the rotation speed cannot be improved, and therefore, the operation is reliable, the service life is greatly prolonged, and the working efficiency is improved.
