[0031] In other embodiments, the axial fixing plate 2 can be connected to the motor control board 1 and integrated with the motor control board 1 .

[0032] The magnetic suspension bearings of the vacuum cleaner motor are all controlled by the motor control board. When the motor starts, it first detects the position of the rotor shaft through the radial position sensor and the axial position sensor, and transmits the deviation signal of the rotating shaft to the motor control board. The controller, the controller performs a moderate calculation on the position deviation signals detected by the radial position sensor and the axial position sensor, and converts the calculated control signal into a control current after passing through the motor power amplifier, and the control current generates a magnetic force in the magnetic suspension bearing , so as to drive the rotor shaft to correct the position. Therefore, the rotor shaft can quickly return to the reference position. After...

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 (5) and a rotor (6). The vacuum cleaner motor is provided with the magnetic bearing capable of suspending the rotor (6) in the stator (5). The rotor (6) comprises a rotor shaft (11), the magnetic bearing comprises a lower axial magnetic bearing (9) provided at one end of the rotor shaft (11) for axially adjusting the position of the rotor shaft (11), and the other end of the rotor shaft (11) is provided with an axial fixing plate (2) for axially adjusting the position of the rotor shaft (11). The vacuum cleaner is provided with the vacuum cleaner motor. The vacuum cleaner motor comprises a controller. The controller actively adjusts the speed of the rotor 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.

Description

technical field [0001] The invention relates to the technical field of vacuum cleaners, in particular to a high-speed brushless vacuum cleaner motor and a vacuum cleaner using magnetic suspension bearings. Background technique [0002] Vacuum cleaner motors are required to have small volume and high speed. At present, most of the main vacuum cleaner products at home and abroad use series motors or brushed DC motors. In order to achieve miniaturization and weight reduction while satisfying greater suction effects, it is often necessary to increase the speed. However, this type of motor is generally composed of a casing, permanent magnet steel, carbon brushes, rotors and rotor windings. During operation, high-speed friction will be generated between the carbon brushes and the commutator while the rotor windings are constantly switching currents. As a result, sparks are easily generated between the carbon brush and the commutator. If the speed is too high, it will cause seriou...
