Problems solved by technology

[0002] When the compressor is running at high speed, the balance weight will stir the refrigerant gas on the side of the compression mechanism (that is, the side of the motor facing the compression mechanism), causing the refrigerant gas on the side of the anti-compression mechanism (that is, the side of the motor facing away from the compression mechanism) The separation effect of the oil contained in the gas is reduced, and the refrigerant gas containing the oil is discharged into the refrigeration cycle system, reducing the amount of oil in the oil pool in the compressor
In addition, in order to return the oil separated from the refrigerant gas on the side of the anti-compression mechanism to the side of the compression mechanism, it is necessary to increase the area of ​​the notch of the motor stator, which degrades the motor characteristics of the compressor.

Abstract

The invention discloses a motor rotor for a compressor, a motor for the compressor, and the compressor. The motor rotor for the compressor comprises a rotor iron core and at least one balance block, wherein the rotor iron core is provided with a compression end and a decompression end in an axial direction; the balance block comprises a mounting part and a balance part; the mounting part is mounted on at least one end plane of the compression end and the decompression end of the rotor iron core; the balance part is connected with the surface, opposite to the end plane, of the mounting part, and can extend in the circumference direction of the rotor iron core; and an inclined plane which is tilted relative to the end plane is arranged between the outer end plane and the outer circumferential surface of the balance part. According to the motor rotor for the compressor provided by the invention, the motor rotor is particularly applicable to high-rotary-speed operation; under a condition that the motor characteristic of the compressor is ensured, the separation effect of oil and liquid contained in a refrigerant gas can be improved; the oil liquid flowing in a refrigerating and circulating system can be restrained; and the oil amount in the compressor can be ensured.

Description

technical field [0001] The invention relates to the technical field of compressor manufacturing, in particular to a motor rotor for a compressor, a motor for a compressor having the motor rotor for a compressor, and a motor for a compressor having the motor rotor for a compressor compressor. Background technique [0002] When the compressor is running at high speed, the balance weight will stir the refrigerant gas on the side of the compression mechanism (that is, the side of the motor facing the compression mechanism), causing the refrigerant gas on the side of the anti-compression mechanism (that is, the side of the motor facing away from the compression mechanism) The separation effect of the oil contained in the gas is reduced, and the refrigerant gas containing the oil is discharged into the refrigeration cycle system, reducing the amount of oil in the oil pool in the compressor. In addition, in order to return the oil separated from the refrigerant gas on the anti-com...
