Abstract

The invention discloses a motor rotor. The motor rotor comprises a rotor core in which an axle hole is arranged, wherein the periphery of the axle hole is provided with multiple inner rotor slots and multiple outer rotor slots all which are spaced along the radial direction of the rotor core and along the circumferential direction of the rotor core, and each inner rotor slot is arranged inside the outer rotor slot along the radial direction of the rotor core; the motor rotor further comprises multiple inner conductive strips, multiple outer conductive strips and an end short-connection ring; said multiple inner conductive strips are respectively inserted in said multiple rotor slots, said multiple outer conductive strips are respectively inserted in said multiple outer rotor slots, and the electrical conductivity of each outer conductive strip is different from that of the inner conductive strip; the end short-connection ring is arranged on both ends of the rotor core, and said inner conductive strips and said outer conductive strips are respectively connected through the end short-connection ring. According to the motor rotor, the motor is better in start ability, and higher in operation efficiency, meanwhile high-temperature oxidation can be effectively avoided in a formation process, and the process can be simply and conveniently realized.

Description

technical field [0001] The present invention relates to the technical field of compressors, in particular to the technical field of rotary compressors, and more specifically to a motor rotor. Background technique [0002] The rotors of double squirrel-cage motors are mostly made of single conductive material such as cast aluminum, and the inner and outer squirrel cages are made of the same conductive material, so the performance of the motor cannot be optimal. The structure of the motor needs to be improved. Contents of the invention [0003] This application is based on the inventor's discovery and recognition of the following facts and problems: [0004] A copper-aluminum composite double squirrel-cage rotor is disclosed in the related art. In this structure, the inner and outer cage cavities are in communication with each other. The inventors of the present application found that the conductor materials in the inner and outer squirrel cage cavities are in contact wit...
