| description | The utility model discloses a powder metallurgy iron core rotor for a compressor, which comprises a rotor iron core arranged at the center and a magnetic steel group arranged outside the rotor iron core, and the magnetic steel group is fixedly connected with the rotor iron core. By means of the structure that the segmented skewed pole magnetic steel is attached to the surface of the integrally-formed powder metallurgy rotor iron core, the segmented skewed pole structure of the rotor is simplified, the mold cost and the assembly process difficulty are reduced, the cogging torque is improved, the torque pulsation is reduced, the harmonic magnetic field is weakened, meanwhile, the size precision of the rotor is improved, and the diversity of the rotor structure is improved; motor vibration noise is effectively improved, and motor operation stability is improved.
本实用新型公开了一种压缩机用粉末冶金铁芯转子，包括设置在中心处的转子铁芯、以及设置在转子铁芯外部的磁钢组，所述磁钢组与转子铁芯固定连接。通过在一体成型的粉末冶金转子铁芯表面贴设分段斜极磁钢的结构，简化了转子分段斜极结构，降低了模具成本及装配工艺难度，改善齿槽转矩，降低转矩脉动，削弱谐波磁场，同时提高转子 |
