基于51单片机实现的步进机控制系统

摘要

步进电机是ー种进行精确步进运动的机电执行元件,它广泛地用于エ业机械的数

控制。为使系统的可靠性,通用性,可维护性以及性价比最优,根据控制系统功能要求

及步进电动机应用环境,确定了设计系统硬件和软件的功能划分,从而实现了基于8051

单片机的四相步进电动机的开环控制系统。控制系统通过单片机存储器、!/O口、中断、

键盘、LED显示器的扩展,步进电动机的环形分配器、驱动及保护电路、人机接口电路、

中断系统及复位电路、单电压驱动电路等的设计。实现了四相步进电动机的正反转、急

停等功能。为实现单片机控制步进电动机系统在数控机床上的特殊应用,系统设计了两

个外部中断,以实现步进电动机在某段时间内的反复正反转功能,也即数控机床的刀架

自动进给运动。
