The Servo System Design of Stepping Motor and Realization of Visual Simulation

A servo system of stepping motor-base on AT89C51 chip microcomputerwas introduced. The system used computer for epipetalous control and chip microcomputer for hypogynous control. It used computer software to replace the traditional stepping motor controller, which consist of buffering memorizer, annular allotter, control logic, and control gate of clockwise or counter clockwise. It can easily control stepping motor's tuming direction, speed, and Corner. In addition, by researching the basic theory and realizing method of visual simulation, this paper gave emphasis to the method of upbuilding triaxial entity model of stepping motor on 3DS MAX, then connecting the entity model with the stepping motor control parameters on Visual Basic, and realizing the visual simulation of the stepping motor's working process. The practical application show this system has high dependability and flexibility, better practicability.
