摘要:步進電動機由于用其組成的開環系統既簡單、廉價,又非??尚?,因此在打印機等辦公自動化設備以及各種控制裝置等眾多領域有著極其廣泛的應用。

   本文介紹的是一種基于單片機的步進電機的系統設計,用C語言編寫出電機的正轉、反轉、加速、減速、停止程序,通過單片機、電機的驅動芯片ULN2803以及相應的按鍵實現以上功能,本文內容介紹了步進電機以及單片機原理、該系統的硬件電路、程序組成,同時對軟、硬件進行了調試,同時介紹了調試過程中出現的問題以及解決問題的方法。該設計具有思路明確、可靠性高、穩定性強等特點,通過調試實現了上述功能。

關鍵詞:步進電機;AT89C51;驅動機構;轉動

 

Abstract:The open-loop system which is composed by step-motor is simple, cheap and very practical, so there are very wide range of applications in printers and other office automation equipment and various control devices, and many other fields. 

     This article describes one design of step-motor system based on microcontroller.The program of the preparation of a motor , reverse, speed up, slow down, stop is written by compile language. The above functions are realized through the microcontroller, motor driver chip ULN2083 and  correspond key . 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 the advantages of clear , high reliability, strong stability, etc.,and the above-mentioned functions are realized through the debugging.  

Key Words: Stepper motor;AT89C51; driving mechanism; rotation
