The invention relates to a high-precision rotator which comprises an apex, a pedestal, a main shaft, a shaft sleeve, a socket sleeve, a motor and a motor socket sleeve, wherein the apex is connected with the main shaft through the pedestal; the main shaft is fixed with the socket sleeve through the shaft sleeve; and the motor is fixed in the motor socket sleeve and directly connected to the main shaft. The direct connection of the motor and the main shaft replaces the connection by using a coupling in the traditional method, thereby realizing the precise synchronization of the motor and the main shaft, and also realizing the high-speed high-precision transmission; and the invention adopts a full fixed main shaft and most of the main shaft is connected with the socket sleeve through the shaft sleeve, thus the stability and transmission precision of the motor can be well ensured at the start and stop moments.
