Problems solved by technology

[0005] The purpose of the present invention is to propose a hair dryer motor and a hair dryer, which solves the problem that the existing motor cannot increase the speed due to the limitation of the bearing, so that the maximum speed of the motor can reach 150,000 RPM, which not only operates reliably, but also greatly prolongs the service life. Improved work efficiency

Embodiment Construction

[0023] 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.

[0024] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0025] like figure 1 As shown, a hair dryer motor provided by an embodiment of the present invention includes a stator 3, a rotor 2 rotatably arranged in the stator 3, the rotor 2 includ...

Abstract

The invention relates to the technical field of hair driers and particularly relates to a hair drier motor adopting a magnetic bearing. The hair drier motor comprises a stator and a rotor, wherein the rotor comprises a rotor permanent magnet and a rotor shaft; the rotor shaft is sleeved with at least one radial magnetic bearing and at least one axial magnetic bearing; the rotor permanent magnet is arranged at the end part close to the rotor shaft; the radial magnetic bearing and the axial magnetic bearing are arranged at one end, extending outwardly from the rotor permanent magnet, of the rotor shaft; a groove is arranged in the axial magnetic bearing; the rotor shaft is provided with a bulge accommodated in the groove; and through match between the groove and the bulge, deflection of the rotor shaft along the axial direction is limited. The hair drier comprises the hair drier motor. According to the hair drier motor and the hair drier, the problem that the rotation speed can not be improved when the existing motor suffers from bearing limitations can be solved, 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 hair dryers, in particular to a hair dryer motor using a magnetic suspension bearing and a hair dryer with the hair dryer motor. Background technique [0002] The hair dryer is mainly used for drying and shaping hair, but it can also be used for partial drying, heating and physical therapy in laboratories, physiotherapy rooms, industrial production, art, etc. It is composed of a set of heating wires and a small high-speed fan. into. When energized, the heating wire will generate heat, and the wind blown by the fan will become hot air after passing through the heating wire. [0003] According to the type of motor it uses, it can be divided into AC series excitation type, AC shaded pole type and DC permanent magnet type. The advantage of the series-excited hair dryer is that it has a large starting torque and a high speed, and is suitable for manufacturing high-power hair dryers; the disadvantage is that ...
