CNC machine tool is orientating to the direction of sophisticated, high-speed, complex, intelligent, and environmentally friendly. Precision and high-speed processing requires a higher requirement for transmission and controller: Higher dynamic performance and control precision, higher feed rate and acceleration, lower noise and vibration and less wear and tear. The symptom of the problem is that when the traditional transmission chain goes trough the motor, it must be through the gears, worm gear, belts, Ball Screw, couplings, clutches and other transmission links, and there will produce greater inertia, elastic deformation, Backlash, motion lag, friction, vibration, noise and wear in these link. Although there are some promotion after continuous improvement, but it is difficult to solve the problem fundamentally. So the concept of "direct drive" was appeared, which abandon intermediate links from the motor to the various components. With the development of motor and drive control technology, Spindle, the "direct drive" of linear and rotary coordinates movement concept has came into reality. The use of Linear motor and its drive control technology in the machine tool made significant changes in the structure. Linear Motor and General Motors is similar in principle, it is only the extent of the motor cylinder; its categories are the same with the traditional motor. Such as: DC motor, AC permanent magnet synchronous linear motor, AC induction motor and stepper motor.
