Abstract

The invention discloses a rotor punching sheet, a rotor core, a motor, and a compressor. The cis provided with an axle hole and a plurality of magnet grooves surrounding the circumference of the axlehole at intervals; a first through hole, a second through hole and a third through hole which are separated along the circumference at intervals and penetrate through the rotor punching sheet in the thickness direction, are formed between each magnet groove and the outer contour of the rotor punching sheet; the second through hole is located between the first through hole and the third through hole; the first through hole, the second through hole and the third through hole can penetrate through one of the circumferential wall of the magnet groove and the outer circumferential wall of the rotorpunching sheet; and at least one of the first through hole, the second through hole and the third through hole penetrates through the circumferential wall of the magnet groove. The rotor punching sheet can give consideration to the concentricity between the stator and the rotor, and can reduce the low space order low frequency radial load of the motor at the same time, thus improving the motor performance and being simple in manufacturing technology.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a rotor punch, a rotor core with the rotor punch, a motor with the rotor core and a compressor with the motor. 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 stamping, which can reduce the low spatial order and low frequency radial force of the motor while taking into account the concentricity of the rotor, improve the performance of the motor, and has a simple manufacturing process. [0004] The present invention further proposes a rotor iron core with the above-mentioned rotor...
