[0002] A linear motor is a transmission device that converts electrical energy directly into linear motion mechanical energy without any intermediate conversion mechanism. The working principle of a linear motor is similar to that of a pile driver. It is actually a spring mass block that moves in a linear form. It is a starting module that directly converts electrical energy into linear motion mechanical energy. Since the mass block is directly driven to move linearly, the response speed is very fast and the vibration is very strong.
