Patent number: 11735979Abstract: Disclosed are a motor rotor and a permanent magnet motor. The motor rotor includes: a rotating shaft; a magnetic layer fixedly sleeved on the rotating shaft; a first heat diffusion layer wrapped on an outer surface of the magnetic layer away from the rotating shaft for preventing a shielding layer from overheating locally; and the shielding layer wrapped on a surface of the first heat diffusion layer away from the magnetic layer. The first heat diffusion layer is provided between the shielding layer and the magnetic layer of the motor rotor, so that the first heat diffusion layer can prevent the shielding layer and the magnetic layer from overheating locally, and improve heat dissipation efficiency of the shielding layer.Type: GrantFiled: May 6, 2021Date of Patent: August 22, 2023Assignee: GREE ELECTRIC APPLIANCES, INC.

Publication number: 20230250825Abstract: A compressor includes a drive motor and a wind wheel, wherein the drive motor includes a casing and a rotor, the rotor being rotatably arranged within the casing; the wind wheel is mounted at a first axial end of the rotor. A thrust disc is also provided at the first axial end of the rotor. An axial bearing assembly is arranged between the thrust disc and the wind wheel, and the axial bearing assembly is arranged fixedly with respect to the casing. A first air gap is formed between a first end of the axial bearing assembly and the wind wheel, and a second air gap is formed between a second end of the axial bearing assembly and the thrust disc. The air compressor reduces a tolerance accumulation caused by part cooperation between axial bearing assemblies, and more precisely ensures effective working clearances.Type: ApplicationFiled: May 7, 2021Publication date: August 10, 2023Inventors: Yusheng Hu, Bin Chen, Xiaobo Zhang, Jinxin Jia, Jiuzhan Su
