基于 51 单片机步进电机控制系统设计汉字摘要步进电机是一个受，而且能将对应或电动机。因为步进电机含有步距误差不积累、运行可靠、结构简单 、惯性小、成本低等优点，所以，被广泛使用于计算机外围电路、自动化控制装置和其它数字控制装置中，如打印机、钟表、数模转换设备等装置中。伴随科学技术快速进展，对应控制系统也产生了很多个类，步进电机身影在众多领域中能够看到。其中实行单片机作为控制关键控制系统，因为其电路简单、成本低、可靠性强等优点，满足众多领域需求，得到了大量利用。所以，讨论基于单片机步进电 机 控 制 系 统 ，。 本 设 计 讨 论 是 基 于 51 单 片 机。经过单片机 I/O 端口输出时序方波作为控制信号，信号经过芯片 ULN 驱动芯片驱动步进电机进行不一样指令进行工作。依据不一样需要，经过按键电路来控制步进电机启停、正反转和加减速等功效，并在数码管上实时显示步进电机工作状态。本文给出了电路各个模块电路图，并用 ProteusISIS 软件对控制系统各个功效进行了仿真，并给出了对应仿真结果图像。关键词：单片机； 步进电机； 电机驱动； 控制系统Abstract Stepper motor controlled by a pulse signal, and a pulse signal can be converted to the corresponding angular displacement or linear displacement of the digital motor. As the stepper motor has a step error does not accumulate, reliable, simple structure, small inertia, low cost, and therefore, are widely used in computer peripheral circuits, automatic control devices and other digital control devices, such as printers, watches and clocks , digital to analog conversion equipment, and other devices. With the rapid development of science and technology, the corresponding control system also produced many types of stepper motor figure can be seen in many areas. Which uses microcontroller as the control of the control system, because of its simple circuit, low cost, high reliability, etc., to meet the needs of many fields, we get a lot of use. Therefore, based on single-chip stepper motor control...
