2025 届毕业设计报告题目：基于单片机的步进电机控制器设计班 级： 电气 1101 班 学 号： 202500141028 姓 名： 指导老师： 完成日期：2025 年 5 月摘要科技的进展，社会的进步，对产品的要求越来越高。各种精密器件的需求增加，这使得我们对制造产品的机器要求越高。步进电机运行平稳、噪音低、响应快、寿命长、输出扭矩高和控制误差小的特点在国民生产中起着越来越重要的作用。本文介绍利用 AT89C51 单片机来控制步进电机的系统实例。通过按键输入相关数据、LED 灯和步进电动机驱动芯片 ULN2025A，驱动芯片驱动步进电机进行相应的动作。本文步进电机采纳四相单双八拍的励磁方式，不同的 LED 灯的亮，熄灭分别显示步进电机的不同状态，具有实时性的特点。本文也介绍单片机 AT89C51、步进电动机驱动芯片 ULN2025A等元器件的使用方法和运用的场合。文中还提到系统的硬件组成、程序流程图、程序及说明。关键词：单片机、步进电机、控制、驱动、显示Abstract: The development of science and technology, the progress of the society, more high requirements for the product. All kinds of precision devices increase in demand, which allows us to manufacture products that require higher machine. Stepping motor to run a smooth, low noise, fast response, long life, high output torque and control small error plays a more and more important role in national production. This paper introduces the use of AT89C51 microcontroller to control the stepper motor examples of the system. Through the keyboard input data, LED lamp and stepper motor drive chip ULN2025A, driver chip to drive a stepper motor corresponding action. Different LED lamps light, extinguishes show different state of stepper motor, with the characteristics of real-time.The article also introduces the method of use and the use of single-chip AT89C51, step motor driving chip ULN2025A components. The paper also mentions the hardware composition of the system, the program flow chart, procedures and instructions.Keywords...
