Due to the influence of the telescope in its weight and wind load, the reflective surface will have a slight change,then actuators will adjust. The design of the actuator will affect the normal operation of the radio telescope, the late maintenance and service life. The main design of this paper is the actuator, which includes: intelligent stepper motor, brake, bevel gear, cycloid pin wheel reducer, ball screw, etc. The precision of the actuator can affect the precision of the radio telescope.Considering the movement of the actuator principle, understanding the cooperation of each composition, computing the size of the parts and materials should be chosen, also checking the intensity.Based on the pull rod movement speed, to calculate the speed of a ball screw, and based on the ratio of cycloidal pinwheel, to compute intelligent stepper motor speed.Understanding the working principle of the brake and the cycloidal pinwheel.Getting information of the advantages of ball screw, calculating the ball screw and checking the i...
