Problems solved by technology

Due to the high speed, the ball bearing wears quickly, the life is short, and the oil mist lubrication used is more polluted
With the development of new energy technology and the demand for low-carbon environmental protection, high-speed motors have great development prospects in the fields of centrifugal compressors, distributed energy, hybrid vehicles, etc., but the power of high-speed motors used for machine tool processing is generally low , does not meet the needs of these applications

Embodiment Construction

[0018] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0019] The invention is a high-power air suspension permanent magnet high-speed motor, such as figure 1 As shown, it includes: a permanent magnet synchronous motor rotor 1, a motor stator 2 that drives the permanent magnet synchronous motor rotor 1 to rotate, a front radial air bearing 3 that supports the permanent magnet synchronous motor rotor 1, a rear radial air bearing 4 and an axial Thrust air bearing 5, and motor housing 6 surrounding motor stator 2, three air bearings and permanent magnet synchronous motor rotor 1.

[0020] The rotor 1 of the permanent magnet synchronous motor is embedded with magnetic steel on the surface of the rotating shaft, and then ground to precision, which is a surface-inserted rotor. Due to the use of magnetic steel instead of aluminum or copper strips, which are excited by the rotor permanent magnets, the power fact...

Abstract

The invention discloses a high-power air suspension permanent magnet high-speed motor, which comprises a permanent magnet synchronous motor rotor, a motor stator, a front radial air bearing, a rear radial air bearing, an axial thrust air bearing and a motor shell, wherein the permanent magnet synchronous motor rotor is driven by the motor stator to rotate and is suspended and supported through the front radial air bearing, the rear radial air bearing and the axial thrust air bearing; and the motor stator, the front radial air bearing, the rear radial air bearing, the axial thrust air bearing and the permanent magnet synchronous motor rotor are enclosed by the motor shell. Due to the application of the permanent magnet synchronous motor rotor, the magnetic field strength is higher and the size of the rotor is smaller, so that the motor is suitable for a higher rotation speed; and the power of the motor can be greatly increased by synchronously increasing the magnetic field strength andthe rotation speed.

Description

technical field [0001] The invention relates to a high-power high-speed motor, and also relates to a permanent magnet rotor and an air suspension bearing applied to the motor. Background technique [0002] A high-speed motor usually refers to a motor with a speed exceeding 10000r / min. Due to the high speed, the high-speed motor is usually used as a prime mover and directly connected to the actuator, which saves the complicated intermediate speed change mechanism, high transmission efficiency and low noise; at the same time, due to the high speed, The power density of the motor is high, which can effectively save materials and facilitate installation. [0003] High-speed motor is the key technology of high-speed machining. It is widely used in drilling, milling, grinding and other processing machine tools. It is usually called electric spindle. It can not only obtain greater productivity, but also obtain high processing quality and reduce Cost of production. At present, mos...
