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.
