 步進(jìn)電機(jī)是一種易于精確控制的電機(jī)。其良好的性能使其在工業(yè)生產(chǎn)及其它方面受到廣泛的應(yīng)用，特別是近年來(lái)隨著計(jì)算機(jī)數(shù)控技術(shù)和永磁材料的迅速發(fā)展,為步進(jìn)電機(jī)的應(yīng)用開(kāi)辟了廣闊的前景。因此研究步進(jìn)電機(jī)控制系統(tǒng)具有重要的現(xiàn)實(shí)意義。
 本課題研究開(kāi)發(fā)了高性能步進(jìn)電機(jī)控制系統(tǒng)。系統(tǒng)采用功能強(qiáng)大的AT89C51 單片機(jī)作為CPU，采用串行顯示接口電路顯示電機(jī)的轉(zhuǎn)速，SPGT62C19B芯片作為步進(jìn)電機(jī)的驅(qū)動(dòng)，省去了昂貴的專用步進(jìn)電機(jī)控制器。依靠AT89C51單片機(jī)的對(duì)雙極性兩相四拍步進(jìn)電機(jī)進(jìn)行控制。本文給出了其系統(tǒng)的工作原理、硬件電路及部分軟件程序，并對(duì)系統(tǒng)的安全性、可靠性和抗干擾能力等方面進(jìn)行了分析。
 單片機(jī)控制步進(jìn)電機(jī)系統(tǒng)具有功能靈活多樣、脈沖輸出準(zhǔn)確、實(shí)時(shí)性強(qiáng)、成本低、硬件線路簡(jiǎn)、系統(tǒng)可靠性強(qiáng)等特點(diǎn)，并且通過(guò)軟件設(shè)計(jì)可以實(shí)現(xiàn)各種復(fù)雜的控制。

Abstract
 Stepping motor is an electrical machine which could be controlled accurately. Thanks to its fine functions, it has been popularized in the industrial production. With the rapid development of the computer digital controlled technology and the permanent magnetism materials, it has been opened a promising prospect for the application of the stepping motor. Therefore it’s very meaningful to study the stepping motor controlled system.
 High-performance stepping motor control system has been developed. Single-chip microcomputer is used as the CPU, SPGT62C19B is chosen as the drive of the stepping motor, so the expensive exclusive controller for the stepping motor could be omitted. two_phase four_beat stepping motor is controlled by the single-chip microcomputer　AT89C51. The working principle of the system, the hardware circuit and some software program are demonstrated, the safety, reliability and the anti-jamming are analyzed.
 Single-chip microcomputer controlled stepping motor system is characterized by the flexibility, diversity in the function, accuracy in the pulse output, strong real time, low-cost, the simplify in the hardware circuit, and reliabity of the system. The software could accomplish all kinds of complicated controlling.
