摘 要：步进电机是近年来发展较快、具有广阔应用前景的 Abstract: The stepper motor is a rapid development in recent years, has broad application prospects of a motor. Open-loop control system by a stepping motor control is simple, inexpensive, highly feasible, and thus has a broad scope of application in everyday life. This article describes a microcontroller-based stepper motor controller design through a C language program, the motor of the manual control and automatic control functions. Manual control of the motor forward, reverse, speed up, slow down, stop, run, and other functions. The automatic control is automatically controlled according to temperature changes in the corresponding speed. The above functions are realized through the microcontroller, motor driver chip ULN2003 , Sensor data acquisition block and correspond key , and the work state of stepper motor is displayed through the LCD screen. This article introduces the principle of stepper motor and single-chip microcomputer, the system hardware circuit, the program components, while software and hardware for the debugging, at the same time introduces the problems which are appeared in the debugging process and the solutions of the problems . The design has high reliability, stability, and feature-rich and other characteristics. Key Words: Stepper motor, SCM, Drive System, Rotation, Control.目 录 摘 要 Ⅰ Abstract Ⅱ 序言 1 第1章 绪论 2 1.1 课题研究的目的以及意义 2 1.2 国内外研究现状 2 1.3 论文的主要研究内容 2 第 2 章 单片机和步进电机简介 4 2.1 单片机介绍 4 2.1.1单片机原理简介 4 2.1.2单片机的应用系统 4 2.1.3 AT89C52简介 5 2.2 步进电机介绍 7 2.2.1 步进电机概述 7 2.2.2 步进电机的工作原理 9 2.2.3 步进电机的分类与选择 10 2.3 步进电机驱动系统介绍 11 2.3.1 步进电机驱动系统简介 11 2.3.2 步进电机绕组的电气特性 11 第 3 章 仿真软件proteus简介 14 第 4 章 系统方案设计 15 4.1 设计方案 15 4.2 工作原理 15 第 5 章 系统整体硬件结构 16 5.1 系统原理图 16 5.2 时钟部分 16 5.3 键盘部分 17 5.4 步进电机驱动部分 18 5.5 传感器数据采集部分 18 5.6 状态指示部分 19 第 6 章 系统软件设计 20 6.1 系统开发软硬件环境 20 6.2 系统主程序 20 第 7 章 系统的调试与检测 22 第 8 章 设计总结与展望 23 致 谢 24 附 录 25 参考文献 35 序 言 步进电机是近年来发展较快、具有广阔应用前景的已成为直流电机和交流电机以外的第三类电动机。步进电机是一种由电脉冲控制的特殊同步电动机，它的作用是将
