Abstract

The invention discloses a rotor sheet, a rotor iron core and a motor; a shaft hole and multiple magnet slots arranged around the shaft hole circumferentially at intervals are arranged on the rotor sheet, and a projection of the rotor sheet in a base face is separated into multiple unit parts by multiple straight lines crossed through the center of the shaft hole; one magnet slot is arranged on every unit part, and the base face is a plane which is axially perpendicular to the rotor sheet; a first through hole, a second through hole and a third through hole separated along the circumferential direction and penetrated through the rotor sheet on axial direction are arranged on every unit part; the first through hole, the second through hole and the third through hole are located between the magnet slot and an outline of the unit part, and the first through hole and the third through hole are distributed at both sides of the center line of the second through hole. According to the rotor sheet, the concentricity of a fixed rotor is guaranteed; meanwhile, a low space order low-frequency radial force of a motor is reduced, the motor low-frequency vibration is reduced, and the motor performance is promoted.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a rotor punch, a rotor core with the rotor punch and a motor with the rotor core. 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 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. [0004] The present invention also proposes a rotor iron core with the above-mentioned rotor punch. [0005] The presen...
