With the development of society, the performance of linear motor is getting better and the cost is decreasing, which creates conditions for its application; On the other hand, the application industry of optical fiber laser cutting machine, such as sheet metal industry, constantly puts forward high requirements for cutting quality and cutting efficiency. Therefore, the fiber laser cutting machine driven by linear motor came into being. Because of its fast speed, large acceleration and high positioning accuracy, it is deeply favored by customers in the market. Linear motor is a driving device that directly converts electric energy into kinetic energy of linear motion by using the principle of electromagnetic induction. It is a motor that can realize reciprocating linear motion. Compared with traditional rotary motor, linear motor has the following advantages:

1. High speed, high acceleration;

2. High precision;

3. No mechanical wear

4. The transmission system has simple structure and high efficiency;

5. Low noise, quiet operation.
