研究并实现了较大功率步进电机的驱动控制系统。采用分立元件搭建功率驱动电路,在充分研究SI-7600时序分配器的基础上,对不同控制方式进行了对比研究,分析了电路设计中存在的问题并提出了有效的解决方案,成功地实现了电机的正转、反转、加速、减速、启动和停止等功能。实验证明:系统运行稳定可靠。能广泛应用于数字控制领域。

One studies and achieves a stepping motor drive control system with the large power. One builds a power drive circuit using discrete components which fully guarantees the reliability and stability of the circuit running through the reasonable circuit design of signal conditioning circuit and protection circuit. On the basis of studying the SI-7600 timing distributor, one studies different control methods of running by comparing, and proposes effective solutions by analysis problems that may occur. Moreover, one achieves the function that motor runs forward, reverse, accelerates, decelerates, starts, stops. Experiments show that the system is stable, strong anti-interference ability, which can be widely used in the field of digital control. The system has important practical value.
