摘  要

步進(jìn)電動(dòng)機(jī)突出的優(yōu)點(diǎn)是它可以在寬廣的頻率范圍內(nèi)通過(guò)改變脈沖頻率來(lái)實(shí)現(xiàn) 調(diào)速，快速起停、正反轉(zhuǎn)控制及制動(dòng)等，并且由其組成的開(kāi)環(huán)系統(tǒng)既簡(jiǎn)單、廉價(jià)，又非常可靠，因此在眾多領(lǐng)域有著極其廣泛的應(yīng)用。研制一種高性能步進(jìn)電機(jī)轉(zhuǎn)速驅(qū)動(dòng)器及其控制系統(tǒng)具有重要的意義。
本文研究開(kāi)發(fā)的步進(jìn)電機(jī)轉(zhuǎn)速控制器，介紹了一種由AT89C52及脈沖分配器PMM8713控制步進(jìn)電機(jī)的實(shí)用電路。詳細(xì)的介紹了步進(jìn)電機(jī)的原理，控制電路，鍵盤(pán)顯示電路、驅(qū)動(dòng)電路及其軟件控制步進(jìn)電機(jī)轉(zhuǎn)速的方法。
本文開(kāi)發(fā)的步進(jìn)電機(jī)控制系統(tǒng)采用用戶(hù)輸入步進(jìn)電機(jī)步數(shù)，并對(duì)步進(jìn)電機(jī)的運(yùn)轉(zhuǎn)采用梯形速度控制，有效的防止步進(jìn)電機(jī)的失步，并且采用LCD顯示實(shí)現(xiàn)人機(jī)對(duì)話(huà)等功能。該電路可用于多種步進(jìn)電機(jī)控制場(chǎng)合。整個(gè)系統(tǒng)結(jié)構(gòu)簡(jiǎn)單，可靠。

Abstract

The advantages of stepping motor are that it’s able to realize regulating-rate，quickly rise-stop，positive-reverse controlling ,braking in wide rage of frequency by changing the frequency of pulse. The stepping motor opening-ring system is simple，cheap and stability，therefore its application is very extensive in many areas. It has great signification to design a high-performance speed driver and its control system of stepping motor.
A speed controller of stepping motor has been developed，and the article introduces a practical circuit by using AT89C52 and the pulse distributor PMM8713 to control stepping motor. Describe the theory of stepping motor, control circuit, keyboard input and LCD display circuit，driving circuit and a way of controlling the speed of stepping motor by software.
The stepping motor control system which this article develops uses the way of that a user input steps of stepping motor, use trapezoidal speed control to the operation of the stepping motor, it is effective to prevent the out-of-step of the stepping motor, and adopt LCD display to realize a man-machine conversation function and so on, This system can be applied in many stepping motor control occasions, the overall system is simple and reliable structure.
