Abstract

The invention discloses a motor for a compressor and the compressor with the motor. The motor comprises a stator and a rotor, wherein the stator comprises a stator core; the stator core comprises tooth parts and a yoke part; a slot part is defined between any two adjacent tooth parts; an auxiliary slot is formed in the middle part of the inner lateral surface of each tooth part; the rotor is arranged on the inner side of the stator. According to the motor for the compressor, the order where air-gap flux density harmonics appear can be reduced, so that radial magnetic pull to the stator is reduced, and the electromagnetic noise of the motor is improved.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a motor for the compressor and a compressor with the motor. Background technique [0002] Rotary compressors are widely used in refrigeration equipment such as air conditioners and refrigerators. The rotary compressor includes a compression mechanism and a drive motor. The drive motor drives the crankshaft of the compression mechanism to rotate to compress the refrigerant entering the cylinder. When the rotary compressor is in operation, its drive motor will generate a lot of noise, and the drive motor with high operating noise is a technical problem that those skilled in the art have been eager to solve. Contents of the invention [0003] This application is made based on the inventor's discovery and understanding of the following facts and problems: in some motors, multiple (two or more) auxiliary slots are provided on the inner side of the teeth of the stator, the role of the auxi...
