Abstract

The invention discloses a motor rotor and a motor. The motor rotor is installed on a rotating shaft of the motor and comprises a rotor body which is arranged to be cylindrical and is fixedly arranged on the rotating shaft, the outer peripheral face of the rotor body is provided with multiple first skewed slots and multiple second skewed slots in parallel arrangement, and inclination angles formed between the first skewed slots and the second skewed slots and the same end of the rotor body are different. According to the technical scheme provided by the invention, combined harmonic distortion can be inhibited, electromagnetic vibration of the motor using the motor rotor is effectively weakened, and electromagnetic noise of the motor is reduced.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor rotor and a motor. Background technique [0002] During the operation of common motors (such as squirrel cage motors), since the motor magnetic field is a combined magnetic field, harmonics of various orders other than the fundamental wave will be generated, and the harmonics themselves and the harmonics of different orders are mutually related The role of the electromagnetic noise will be generated. At present, linear skews are usually used to suppress harmonic distortion on the rotor of a motor. However, linear skews can only suppress harmonic distortions of a certain order, and the suppression of combined harmonic distortions is minimal. Contents of the invention [0003] The main purpose of the present invention is to provide a motor rotor, which aims at effectively suppressing the combined harmonic distortion in the motor and reducing the electromagnetic noise of t...
