A kind of motor rotor bushing at filtering side of what Pu is closed in the utility model creation system,Inside motor shell of the system for fastening the motor for setting filtering side Pu,And the motor rotor bushing locally it is naked go out the what motor shell on the outside of,Including a body,It has room of the opening towards the motor shell outside,For setting the motor rotor towards the opening in the room,A motor stator around the body is set for ring on the outside of the what body,The what motor rotor sets a flabellum for axis,Wherein,The body is different with the material of the motor shell and the set system is made by PPS； By the what motor rotor bushing and the non-integral molding of the motor shell,So that the motor rotor bushing and the motor shell with for different material,And the motor rotor bushing be PPS it is made and have high temperature resistant and rigidity,Therefore it is able to bear generated high temperature when the motor running,And then the motor is avoided to damage.本新型創作係關於一種過濾幫浦之馬達轉子襯套，係可供穿固設該過濾幫浦之馬達的馬達殼體內部，且該馬達轉子襯套局部裸出於該馬達殼體外側，包括一套體，其具一開口朝該馬達殼體外側之容室，該容室內可供朝該開口設該馬達轉子，於該套體外側可供環設一環繞該套體之馬達定子，於該馬達轉子可供軸設一扇葉，其中，該套體與該馬達殼體之材質相異且該套體係由PPS所製；由於該馬達轉子襯套與該馬達殼體非一體成型，因此使得該馬達轉子襯套與該馬達殼體得以為相異材質，而該馬達轉子襯套為PPS所製且具有耐高溫及剛性，因此得以承受該馬達運轉時所產生的高溫，進而避免該馬達損毀。
