The name of linear module is also varied, including linear unit, electric cylinder, slide table, linear stage and mechanical arm. Although the name is different, its working principle is the same.
It can be divided into belt driven, ball screw driven type, rack and pinion driven type, electromagnetic driven type and linear motor driven type, and the working principle of first two are the same. They are the modular product which integrates servo motor, screw and timing belt, which convert the servo motor rotation movement into linear motion, at the same time, convert the best advantage of servo motor: speed control precision, precise control of speed, revolution and torque into precise speed, position and thrust control of the actuator, and finally achieve high-precision linear motion. For linear motor driven type, it converts electric energy into linear motion mechanical energy without any intermediate conversion mechanism.
