Based on the driving portion of electrical discharge machine, and through reasonable selection to linear motor, the paper analyzes the commercial application of the servo system of linear motor. First of all, it introduces the basic structures and working principles of linear motor, analyzes comparatively the differences between the linear motor and the conventional rotary motor, and points out the strengths and development advantages of linear motor in modern servo system. Then, by analyzing the superiority of its application in the servo system of the machine tool, and by researching the basic theory of the electromagnetic field, the paper puts forward the mathematical model of permanent magnet linear synchronous motor (PMLSM). Based on the parameters of the cylindrical linear motor, the paper not only advances the hardware architecture design of the driving portion of electrical discharge machine, but also puts forward the application design of linear motor in the electrical discharge machine. At the end, it summarizes the excellent performance of the linear motor.
