Magnetic levitation motor and air conditioner

Abstract

The invention provides a magnetic levitation motor and an air conditioner. The magnetic levitation motor comprises a housing, a rotor assembly (1), a stator assembly (2), a main shaft (3), a mountingframe (4), a radial magnetic levitation bearing (5) and an axial bearing. The mounting frame (4) is fixedly arranged on the housing; the radial magnetic levitation bearing (5) is fixedly mounted on the mounting frame (4); the rotor assembly (1) is sleeved outside the radial magnetic levitation bearing (5); the stator assembly (2) is sleeved on the periphery of the rotor assembly (1); the main shaft (3) is arranged on the axial outer side of the rotor assembly (1) and fixedly connected with the rotor assembly (1); the axial bearing is used for adjusting the axial position of the main shaft (3);and the radial magnetic levitation bearing (5) is used for adjusting the radial position of the rotor assembly (1). According to the magnetic levitation motor, the size of the whole motor in the axial direction can be reduced, the motor can be applied to special occasions such as narrow space, and the application range of the motor is widened.

Description

technical field [0001] The present application relates to the technical field of motor equipment, in particular to a magnetic levitation motor and an air conditioner. Background technique [0002] The magnetic levitation motor uses the electromagnetic force of the magnetic levitation bearing to suspend the motor rotor in the air, so that there is no mechanical contact between the motor rotor and the motor stator, and there is no mechanical friction. It is a low-loss, high-performance bearing. While realizing the high speed of the motor rotor, it also has the advantages of no mechanical wear, low energy consumption, low noise, long life, no lubrication and sealing, no oil pollution, etc. The rotor speed of the magnetic levitation motor is only limited by the tensile strength of the rotor material. Therefore, the peripheral speed of the magnetic levitation motor rotor can be very high, and it is more and more widely used in high-speed equipment. [0003] Magnetic levitation m...

AI Technical Summary

Problems solved by technology

[0003] Magnetic levitation motors are generally equipped with 2 radial magnetic bearings and 1 pair of axial magnetic bearings, plus the motor stator and rotor, resulting in a large size of the whole machine in the axial direction, which cannot be applied to special occasions with small spaces. Applications are limited
