Maglev Refrigeration Compressor

Abstract

The invention provides a magnetic suspension refrigeration compressor, and relates to the technical field of compressors. The magnetic suspension refrigeration compressor comprises a first shell, a stator, a rotor, a magnetic suspension support module, a wiring circuit board, a connecting wire set and a sensor set, wherein the stator is arranged in the first shell and surrounds an electromagneticfield area; the rotor is provided with a permanent magnet part consisting of permanent magnets; the permanent magnet part is positioned in the electromagnetic field area; the magnetic suspension support module comprises a first frame and a second frame; the first frame and the second frame are positioned at two ends of the rotor; the first frame comprises a first wiring part; the second frame comprises a second wiring part; the wiring circuit board is embedded in the first shell, and is electrically connected with the stator and the magnetic suspension support module; the wiring circuit boardis provided with a driving chip; the first wiring part and the second wiring part are electrically connected with the wiring circuit board through the connecting wire set; and the sensor set is used for detecting the position of the rotor and returning data to a driving chip. The magnetic suspension refrigeration compressor can greatly reduce the maintenance time, improves the maintenance efficiency, and reduces the maintenance cost.

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...
