High-rotating-speed motor servo device

The invention relates to the technical field of servo control, in particular to a high-rotating-speed motor servo device. The high-rotating-speed motor servo device comprises a lead screw assembly, a rocker arm assembly and a rotating shaft assembly, the lead screw assembly comprises a lead screw and a lead screw nut, and the lead screw is in threaded connection with the lead screw nut; the rocker arm assembly comprises a first connecting rod and a rocker arm, and the first connecting rod is fixedly connected with the lead screw nut and rotationally connected with the rocker arm. The rotating shaft assembly comprises a rotating shaft, and the rocker sleeves the outer circle of the rotating shaft and is fixedly connected with the rotating shaft. The axis of the lead screw is perpendicular to the axis of the rotating shaft in space, the design allowance of the device is large, the jamming phenomenon cannot occur in the transmission process, the transmission efficiency of the whole device is improved, and the re
