Abstract

The invention discloses bearing control method and device, a storage medium and a processor. The method comprises the steps that a target protection threshold value of a magnetic suspension bearing isdetermined according to a gap between a rotor of the magnetic suspension bearing and a stator of the magnetic suspension bearing; position parameters of the rotor of the current magnetic suspension bearing are obtained; and based on the relation between the position parameters of the current rotor and the target protection threshold value, a running state of the current magnetic suspension bearing is adjusted. According to the method, the device, the storage medium and the processor, the problem that a fixed protection threshold value is set for protecting the magnetic suspension bearing andthe stable operation of a magnetic suspension compressor is influenced in the related art is solved.

Description

Technical field [0001] This application relates to the field of bearings, and in particular to a bearing control method, device, storage medium and processor. Background technique [0002] Magnetic bearing is a new type of high-performance bearing that can use controllable electromagnetic force to suspend the rotor at the center of the stator and rotor. Since the gap between the stator and rotor of the magnetic bearing is usually only a few hundred μm, the accuracy of the rotor operation control is very high, so In related technologies, a fixed protection threshold is usually set in the control program of the magnetic bearing. When the rotor operation accuracy exceeds this threshold, the magnetic bearing stator and rotor collision can be judged, and the magnetic bearing control system will perform software protection. [0003] However, in magnetic levitation centrifugal compressors, many parts on the rotor need to be hot-assembled. Due to various factors such as the material of the...
