Abstract

The present invention relates to the technical field of compressors, and in particular relates to a compressor rotor and a compressor including the same. The compressor rotor includes a rotor core, and the rotor core is provided with circulation holes for circulating refrigerants. One end of the rotor core is provided with a lower end ring, and the other end of the rotor core is connected with a flow guiding structure for guiding the refrigerants to be discharged from the radial direction of a rotor, and the flow guiding structure can speed up the flow of the refrigerants flowing through the rotor, and increase the circulation volume of the refrigerants.

Description

technical field [0001] The present invention relates to the technical field of compressors, and in particular, to a compressor rotor and a compressor including the same. Background technique [0002] The motor currently used in the fixed frequency compressor is an induction motor, and its rotor is usually made of cast aluminum. The cast aluminum part forms a closed cage conductor, which generates an induced current in the alternating magnetic field to form a rotor magnetic field, which interacts with the stator magnetic field to drive The motor is running. The conductor aluminum cage can be regarded as three parts, the upper end ring, the aluminum strip, and the lower end ring, which are integrally die-cast during production. [0003] The high-pressure refrigerant compressed by the compressor pump body is discharged upward to the compressor through the stator trimming, the air gap between the stator and the rotor, or the rotor through-hole, etc. The current cast aluminum r...
