The invention discloses a rotor core, motor, a compressor, and a refrigeration system with the compressor. The rotor core is formed by intersection and overlapping of at least one group of first rotorpunching sheets and at least one group of second rotor punching sheets; the first rotor punching sheet and the second rotor punching sheet are each provided with an axle hole and a plurality of magnet grooves surrounding the circumference of the axle hole at intervals, and a first through hole, a second through hole and a third through hole are formed between each magnet groove and the outer contour of the rotor punching sheet; the second through hole in the first rotor punching sheet penetrates through the circumferential wall of the magnet groove; the first through hole and the third through hole in the first rotor punching sheet penetrate through the outer circumferential wall of the first rotor punching sheet; the second through hole in the second rotor punching sheet penetrates through the outer circumferential wall of the second rotor punching sheet; and the first through hole and the third through hole in the second rotor punching sheet penetrate through the circumferential wall of the magnet groove. The rotor core can guarantee the concentricity of the stator and the rotor and also reduce the low space order low frequency radial load of the motor at the same time, and canreduce wind polishing loss because too many grooves are formed in the periphery of the rotor.
Description
technical field [0001] The invention relates to the technical field of refrigeration, in particular to a rotor core, a motor with the rotor core, a compressor with the motor and a refrigeration system with the compressor. Background technique [0002] The motor in the related art cannot take into account the concentricity of the stator and the rotor and the low spatial order and low frequency radial force of the motor, and the performance of the motor is poor. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, the present invention proposes a rotor core, which can reduce the low spatial order low-frequency radial force of the motor while ensuring the concentricity of the stator and rotor, reduce the low-frequency vibration of the motor, and improve the performance of the motor, and It can reduce the wind mill loss caused by too many grooves on the outer circ...
