Abstract

The invention provides a stator punching sheet, a stator and a motor. The stator punching sheet comprises a punching sheet body; a central hole is formed in the punching sheet body; small grooves andbig grooves are formed in the punching sheet body in the circumferential direction of the central hole; and the punching sheet body is in symmetrical arrangement by taking the central line of the groove openings of the small grooves as the axis. By virtue of the stator punching sheet, the problem of increasing of the motor cost caused by the stator punching sheet in the prior art is solved.

Description

Technical field [0001] The invention relates to the field of motors, and in particular to a stator punch, a stator and a motor. Background technique [0002] At present, refrigerator compressors on the market are divided into fixed frequency and variable frequency compressors. The number of poles of the fixed frequency motor is two poles, and the speed of the motor is different with the power frequency. For 60Hz frequency compressor motor, its rated speed is generally 3550-3580r / min, for 50Hz frequency compressor motor, its rated speed is generally 2950-2980r / min. The frequency conversion motor is controlled by the controller, and the speed is generally 1000-4500r / min. [0003] For compressors using fixed-frequency motors, the electromagnetic noise of the motor is large due to high-speed operation. The noise of the whole refrigerator cannot be reduced, and the inverter motor can run at low frequency, but the control board needs to be added, and the compressor cost is relatively ...
