Abstract

The invention provides a motor stator, a motor, a compressor and refrigeration equipment, the motor stator comprises a stator body and a sound absorption device, the stator body comprises a yoke part and a plurality of tooth parts, the yoke part is provided with a first end face and a second end face which are opposite, the plurality of tooth parts are arranged at intervals along the circumferential direction of the inner side wall of the yoke part, and the first end face and the second end face are opposite to each other. Stator grooves are arranged between adjacent tooth parts, and the outer side wall of the yoke part is provided with trimming grooves penetrating through the first end face and the second end face. The sound absorption device comprises a sound absorption plate, and a plurality of sound absorption holes are formed in the sound absorption plate; the sound absorption plate is arranged on the first end face of the yoke part, and/or the second end face of the yoke part, and/or in at least one trimming groove, and a cavity communicated with the sound absorption hole is reserved between the sound absorption plate and the corresponding mounting face on the yoke part. According to the motor stator, the motor, the compressor and the refrigeration equipment, fluid noise generated when a refrigerant flows through the motor can be effectively reduced, and the noise reduction effect is improved.

Description

technical field [0001] The invention mainly relates to the technical field of compressor noise reduction, and in particular relates to a motor electronics, a motor, a compressor and a refrigeration equipment. Background technique [0002] The bottom cavity in the compressor casing is provided with a pump body, the middle cavity is provided with a motor, and an exhaust port is formed on the top of the casing. When the compressor is running, the high-temperature and high-pressure gaseous refrigerant discharged from the pump body at the bottom enters the middle cavity, and flows through the motor to the upper cavity through the trimming of the motor, and finally is discharged from the exhaust port of the compressor. This process generates significant fluid noise and may cause acoustic resonance of the compressor cavity, resulting in louder noise. The existing noise reduction means such as the built-in muffler of the compressor can no longer meet the noise reduction requirement...
