Rotor, motor adopting rotor and compressor

The invention discloses a rotor, a motor adopting the rotor and a compressor. The rotor includes a rotor iron core, a magnetic steel groove formed in the rotor iron core, magnetic steel arranged in the magnetic steel groove and end plates fixed to the two ends of the rotor iron core; a pad for limiting deflection of the magnetic steel is arranged on each end plate. Deflection of the magnetic steelcan be limited during high-speed running of the magnetic steel, and the vibration noise of the motor is reduced. 本发明公开了种转子及采用该转子的电机和压缩机，其中转子包括转子铁芯、设置在转子铁芯上的磁钢槽、设于磁钢槽内的磁钢、固定在转子铁芯两端的端板，所述端板上设有限制磁钢偏转的垫片。本发明可以限制磁钢在高速运转的过程中发生偏移，降低电机振动噪音。
