The invention provides a compressor motor. The compressor motor comprises a stator, and the stator is formed by overlapping a plurality of punching sheets. The compressor motor further comprises a stator tooth pressing plate used for tensioning the overlaid punching sheets. A plurality of first through holes are evenly formed in the circumferential sides of the punching sheets, the stator tooth pressing plate is provided with second through holes which are communicated with the first through holes, and the number of the second through holes is smaller than the number of the first through holes. The invention further relates to a compressor. According to the compressor motor and the compressor, the first through holes are formed in the punching sheets of the stator, the second through holes in the stator tooth pressing plate are communicated with the first through holes in the punching sheets of the stator, the frictional loss of a motor rotor due to rotation with fluid in the high-speed rotating process is effectively reduced, and the problem that the loss is large when the motor rotor of the high-power motor operates with fluid is solved.
Description
technical field [0001] The invention relates to the field of compressors, in particular to a permanent magnet speed-regulating compressor motor and a compressor used in refrigeration centrifugal compressors. Background technique [0002] Now some refrigeration centrifugal compressor motors are running, in order to reduce the temperature of the motor, such as figure 1 As shown, the refrigerant enters from the front inlet of the motor, and after kneading in the front cavity, enters the rear end of the motor through the heat dissipation air gap, and then returns to the air return end of the compressor through the rear outlet. Among them, the direction of the arrow in the figure represents the flow direction of the refrigerant. When the compressor is not running under full load or overload conditions, the heat of the motor is relatively low, and the entering mist refrigerant condenses and collects in the front cavity of the motor and becomes liquid. As the liquid level rises, t...
