Stepper motor is an open loop servo motion system actuator, it uses the pulse to control and send off the angular displacement. Compared with AC servo motor and DC servo motor, the outstanding advantages of stepper motor is low cost, moreover, it without any accumulation errors. However, the stepper motor has many deficiencies in operation aspect, such as low-frequency oscillation, noise, low distinguish rate etc. these defects have severely restricted the application scope of stepper motor. The running performance of stepper motor has close relationship with motor driver . The shortcomings of the stepper motor can be overcome by the improvements of drive technology. Relative to the other drive, subdivided drive methods not only can reduce the step angle and improve the resolution shelter of stepper motor, but also can reduce or eliminate low-frequency vibration and make the motor run more smoothly. In summary, the effect control of sub-driven is the best.
