With the continuous development of the mechanical automation industry, various new motor technologies are also emerging. Among them, linear servo motor, as a new type of motor technology, is widely used in the mechanical automation industry. This article will explore the principles, characteristics, and applications of linear servo motors in the mechanical automation industry.

1、 The principle of linear servo motor

Linear servo motor is a type of motor that controls motion through electrical signals, and its working principle is basically the same as traditional rotary servo motors. It mainly consists of motors, sensors, controllers, etc. The motor part of a linear servo motor is composed of a magnetic slider and a coil. When current passes through the coil, a magnetic field is generated on the magnetic slider, causing it to move in the direction of the coil. The sensor part of the linear servo motor is composed of a set of photoelectric encoders and a feedback circuit. The photoelectric encoder can accurately measure the position of the magnetic slider, and the feedback circuit can feedback the measured position information to the controller. The controller controls the magnitude and direction of the current based on feedback information, thereby achieving motion control of the linear servo motor.
