Abstract

The control principle of stepper motor which is widely used at present has been analyzed. It adopts 8051 single-chip microcomputer to achieve stepper motor the pulse distribution control, acceleration and deceleration control in the four phase eight beat mode. This study has avoided complex circuit design, solved the stepper motor "step", "overshoot" phenomenon, promoted step motor to be more stable, faster response, more accurate positioning. This control which has the versatility can be achieved by modifying the corresponding circuit and related procedures for different stepper motor. The control which is flexible and convenient, low cost, has the very high use value in the practical application.
