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 in turn. The invention discloses an automatic floating method based on an orthogonal four-point progressive rotation magnetic levitation rotor. First, use the orthogonal four-point progressive rotation method to find the suspension center, 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 levitati...

Abstract

The present invention discloses a magnetic suspended rotor quadrature four point progressive rotation method and a quadrature four point progressive rotation-based automatic suspension method. Firstly a suspension center is found by use of the quadrature four point progressive rotation method, then a suspension position is found by use of the quadrature four point progressive rotation method, and the suspension is tried. If the suspension is not successful, the progressive angle of the progressive rotation is modified, the suspension center and the suspension position are again found, and the suspension is tried. By using the method, as long as a magnetic suspended rotor has a suspension center and a suspension position, the suspension center and the suspension position can be finally found to realize suspension. The method can realize automatic suspension in first time suspension, after system parameters change, new parameters can be found for suspension, and suspension and operation reliability of the magnetic suspended rotor can be greatly improved.

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...
