The invention discloses a displacement feedback device for a rotating part, the rotating part is mounted on a rotating shaft, the feedback device comprises a feedback rotating part, a mounting base plate, a feedback pull rod and a feedback sensor, and the feedback rotating part is used for being mounted on the rotating part and can rotate around the axial center line of the rotating shaft; the feedback pull rod is movably connected to the mounting base plate, the feedback pull rod can make contact with the feedback rotating part so as to move along with the axial movement of the rotating part, and the feedback sensor is fixedly connected to the mounting base plate and connected with the feedback pull rod. According to the feedback device, the feedback sensor can be prevented from rotating along with the rotating part, the safety and reliability of the device are improved, it is guaranteed that the device can achieve better dynamic balance, the feedback device can not use an electric slip ring, and therefore t
