Abstract: The traditional servo electromechanical components are usually realized by the combination of screw, servo motor and reduce, the lead screw is connected with the motor shaft through external mechanical linkage. The split transmission mechanism will bring the problems of heavy weight and limited installation space. In order to solve the problems, a small-sized high thrust permanent magnet motor drive mechanism with integral screw shaft and unilateral bearing support was proposed. Under the premise of ensuring the output torque performance, the transmission mechanism which combines the lead screw and the driving motor could simplify the structure, reduce the volume and weight, and reduce the production cost through reasonable synchronous design of the screw and motor.
