本发明公开了一种可用于循环再制造的电机转子，包括外壁设置有若干磁钢的转子硅钢片、保护套、端板和中轴，所述保护套套设于所述转子硅钢片的外部，所述端板设置于所述转子硅钢片的两端，所述中轴穿插于所述转子硅钢片的轴心孔内，且所述中轴的两端分别凸出于两个所述端板，两个所述端板和所述转子硅钢片上对应设置有固定孔，丝杆穿插于所述端板和所述转子硅钢片对应的固定孔内，且丝杆凸出于两个所述端板的两端均螺纹连接有紧定螺丝；保护套和端板与转子硅钢片均为可拆卸连接，在到达使用年限后能够进行拆解，检测转子硅钢片有无问题，便于检修维护和替换，不需要整体更换电机，节约使用成本。

The invention discloses a motor rotor which can be used for recycling and remanufacturing, including a rotor silicon steel sheet, a protective sleeve, an end plate and a central shaft arranged on the outer wall of the rotor silicon steel sheet, the protective sleeve is arranged on the outside of the rotor silicon steel sheet, the end plate is arranged on both ends of the rotor silicon steel sheet, and the central shaft is interspersed in the shaft hole of the rotor silicon steel sheet. The two ends of the central shaft are respectively protruded in the two end plates, the two end plates and the rotor silicon steel sheet is provided with a fixed hole, the lead rod is interspersed in the end plate and the rotor silicon steel sheet corresponding to the fixed hole, and the lead rod protruded in the two ends of the end plate are threaded with a tightening screw; The protective sleeve and the end plate and the rotor silicon steel sheet are detachable, which can be disassembled after the service life, so as to detect whether there is any problem with the rotor silicon steel sheet. It is convenient for maintenance and replacement, and there is no need to replace the motor as a whole, saving the use cost.
