Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a magnetic levitation refrigeration compressor. Background technique [0002] With the development of electronic technology, control engineering, signal processing components, electromagnetic theory and new electromagnetic materials and the progress of rotor dynamics, maglev technology has made great progress in recent years. Magnetic levitation is to use the magnetic principle of "same sex repels each other, opposite sex attracts each other", adds a corresponding electromagnetic field between the rotor and stator of the bearing, and controls the electromagnetic field to make it in a relative "suspension" state. [0003] The magnetic levitation system is composed of four parts: rotor, sensor, controller and actuator. The actuator includes two parts: electromagnet and power amplifier. Magnetic suspension bearing is a kind of magnetic levitation bearing that uses magnetic fiel...
