Embodiment Construction

[0033] The invention discloses an orthogonal four-point progressive rotation method for a magnetic levitation rotor. Take four orthogonal points in the radial plane where the rotor is located, and use the magnetic levitation electromagnetic force to drive the rotor to these four points in sequence according to the established steps. Then four points are simultaneously rotated around the rotating shaft of the rotor by a given angle to generate new four points, and then the rotor is made to these new four points successively. The invention discloses an automatic floating method based on an orthogonal four-point progressive rotation magnetic levitation rotor. Firstly, use the orthogonal four-point progressive rotation method to find the center of suspension, and then use the orthogonal four-point progressive rotation method to find the floating position and try to levitate. If the levitation is unsuccessful, modify the progressive angle of the progressive rotation and re-find th...

Abstract

The invention discloses an orthogonal four-point progressive rotation method for a magnetic levitation rotor and an automatic floating method based on the orthogonal four-point progressive rotation. Firstly, use the orthogonal four-point progressive rotation method to find the center of suspension, and then use the orthogonal four-point progressive rotation method to find the floating position and try to levitate. If the levitation is unsuccessful, modify the progressive angle of the progressive rotation and re-find the levitation center, the levitation position and try to levitate. With the method of the present invention, as long as there is a levitable center and a floatable position for the magnetic levitation rotor, the levitation center and the floatable position can be finally found to realize the levitation. The method disclosed in the present invention can not only realize automatic floating at the first floating, but also can automatically find new parameter floating after system parameters change, which greatly improves the reliability of the magnetic levitation rotor floating and running.

Description

technical field [0001] The invention relates to the technical field of magnetic suspension bearings, in particular to an automatic floating method for a magnetic suspension rotor. Background technique [0002] Magnetic suspension bearings have no mechanical friction and are used in many special occasions. The magnetic bearing suspends the rotor stably in the air, so that there is no mechanical contact between the rotor and the stator during high-speed operation. It has the advantages of no mechanical wear, low energy consumption, high allowable speed, low noise, long life, and no lubrication. Magnetic suspension bearings generally adopt permanent magnetic bias to improve their working efficiency. However, the reliable levitation of the permanent magnetic bias magnetic levitation rotor has always been a very difficult problem. [0003] The levitation of the maglev rotor, especially the first levitation, is a very difficult link in the commissioning and operation of the magl...
