Embodiment Construction

[0022] The traditional motor is composed of a stator and a rotor. The stator and the rotor are connected by mechanical bearings or have mechanical contact, so there is mechanical friction during the movement of the rotor. Mechanical friction causes the components to wear, produces mechanical vibration and noise, and can cause the components to heat up, which will deteriorate the performance of the lubricant. In severe cases, the air gap of the motor will be uneven, the winding will heat up, and the temperature rise will increase, thereby reducing the efficiency of the motor and shortening the motor. service life.

[0023] Attached below figure 1 The technical solutions of the present invention are further described through specific implementation methods.

[0024] Such as figure 1 As shown, a vacuum cleaner motor provided by an embodiment of the present invention includes a stator 6, which is coaxial with the stator 6 and rotates a rotor 7 disposed inside the stator 6. The v...

Abstract

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. A vacuum cleaner motor according to the present invention includes a stator, and rotates a rotor disposed in the stator. The vacuum cleaner motor is provided with a magnetic suspension bearing that suspends the rotor in the stator, and the rotor of the vacuum cleaner motor runs not come into contact with any objects. According to the present invention, there is a vacuum cleaner with the vacuum cleaner motor, the vacuum cleaner motor includes a controller, and the controller actively adjusts the speed of the rotor of the vacuum cleaner motor according to the load in the vacuum cleaner. The vacuum cleaner motor and the vacuum cleaner can overcome the problem that the existing motor cannot increase the rotating speed due to the limitation of the bearing, and the operation is reliable, the service life is greatly extended, 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 using a magnetic suspension bearing and a vacuum cleaner using the motor. Background technique [0002] Vacuum cleaner motors are required to have small volume and high speed while ensuring low noise. 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 t...
