驅動器的細(xi)分原理(li)介紹

在國內(nei)，廣大(da)(da)用(yong)戶對“細(xi)(xi)分(fen)(fen)”還不是(shi)(shi)(shi)(shi)特別了解，有(you)的(de)只是(shi)(shi)(shi)(shi)認為(wei)，細(xi)(xi)分(fen)(fen)是(shi)(shi)(shi)(shi)為(wei)了提高精(jing)度，其實不然，細(xi)(xi)分(fen)(fen)主要是(shi)(shi)(shi)(shi)改善(shan)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)的(de)運行性能，現(xian)說明(ming)如下(xia)：步進(jin)(jin)伺服電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)的(de)細(xi)(xi)分(fen)(fen)控制是(shi)(shi)(shi)(shi)由驅(qu)(qu)(qu)(qu)動(dong)(dong)器(qi)準確控制步進(jin)(jin)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)的(de)相(xiang)(xiang)電(dian)(dian)(dian)(dian)流(liu)(liu)來實現(xian)的(de)，以(yi)二(er)相(xiang)(xiang)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)為(wei)例，內(nei)蒙古驅(qu)(qu)(qu)(qu)動(dong)(dong)器(qi)，假如電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)的(de)額(e)定相(xiang)(xiang)電(dian)(dian)(dian)(dian)流(liu)(liu)為(wei)3A，如果使用(yong)常規驅(qu)(qu)(qu)(qu)動(dong)(dong)器(qi)（如常用(yong)的(de)恒(heng)流(liu)(liu)斬波方式）驅(qu)(qu)(qu)(qu)動(dong)(dong)該(gai)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)，驅(qu)(qu)(qu)(qu)動(dong)(dong)器(qi)公司，電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)每運行一步，驅(qu)(qu)(qu)(qu)動(dong)(dong)器(qi)價(jia)格(ge)，其繞組內(nei)的(de)電(dian)(dian)(dian)(dian)流(liu)(liu)將從(cong)(cong)0突(tu)變為(wei)3A或從(cong)(cong)3A突(tu)變到(dao)0，相(xiang)(xiang)電(dian)(dian)(dian)(dian)流(liu)(liu)的(de)巨大(da)(da)變化(hua)，驅(qu)(qu)(qu)(qu)動(dong)(dong)器(qi)公司，必然會引起電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)運行的(de)振動(dong)(dong)和噪音。如果使用(yong)細(xi)(xi)分(fen)(fen)驅(qu)(qu)(qu)(qu)動(dong)(dong)器(qi)，在10細(xi)(xi)分(fen)(fen)的(de)狀態下(xia)驅(qu)(qu)(qu)(qu)動(dong)(dong)該(gai)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)，電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)每運行一微步，其繞組內(nei)的(de)電(dian)(dian)(dian)(dian)流(liu)(liu)變化(hua)只有(you)0.3A而不是(shi)(shi)(shi)(shi)3A，且(qie)電(dian)(dian)(dian)(dian)流(liu)(liu)是(shi)(shi)(shi)(shi)以(yi)正弦(xian)曲(qu)線規律變化(hua)，這(zhe)樣就大(da)(da)大(da)(da)的(de)改善(shan)了電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)的(de)振動(dong)(dong)和噪音，因此，在性能上的(de)優點(dian)(dian)才是(shi)(shi)(shi)(shi)細(xi)(xi)分(fen)(fen)的(de)真正優點(dian)(dian)。由于細(xi)(xi)分(fen)(fen)驅(qu)(qu)(qu)(qu)動(dong)(dong)器(qi)要準確控制電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)的(de)相(xiang)(xiang)電(dian)(dian)(dian)(dian)流(liu)(liu)，所以(yi)對驅(qu)(qu)(qu)(qu)動(dong)(dong)器(qi)要有(you)相(xiang)(xiang)當高的(de)技術要求(qiu)和工藝要求(qiu)，成本亦會較高。

驅動器概述

步(bu)進(jin)電機驅(qu)動器(qi)是(shi)(shi)一(yi)種將(jiang)電脈(mo)沖(chong)轉化(hua)為角(jiao)位移的(de)執行(xing)機構。當步(bu)進(jin)驅(qu)動器(qi)接收到一(yi)個脈(mo)沖(chong)信(xin)號，它(ta)就(jiu)驅(qu)動步(bu)進(jin)電機按設定(ding)的(de)方向轉動一(yi)個固(gu)(gu)定(ding)的(de)角(jiao)度(稱(cheng)為“步(bu)距(ju)角(jiao)”)，它(ta)的(de)旋轉是(shi)(shi)以固(gu)(gu)定(ding)的(de)角(jiao)度一(yi)步(bu)一(yi)步(bu)運(yun)行(xing)的(de)。可(ke)以通過控制(zhi)(zhi)脈(mo)沖(chong)個數來(lai)(lai)控制(zhi)(zhi)角(jiao)位移量，從而達(da)到準(zhun)確(que)定(ding)位的(de)目的(de)；同時(shi)可(ke)以通過控制(zhi)(zhi)脈(mo)沖(chong)頻(pin)率來(lai)(lai)控制(zhi)(zhi)電機轉動的(de)速度和加速度，從而達(da)到調(diao)速和定(ding)位的(de)目的(de)。

驅動器是什么？

驅(qu)動(dong)器(qi)(qi)（driver）從廣義上指的(de)(de)(de)是驅(qu)動(dong)某類(lei)設備的(de)(de)(de)驅(qu)動(dong)硬(ying)件。在計算機領域驅(qu)動(dong)器(qi)(qi)指的(de)(de)(de)是磁(ci)盤驅(qu)動(dong)器(qi)(qi)。通過(guo)某個文(wen)件系(xi)統格式(shi)化并帶有一個驅(qu)動(dong)器(qi)(qi)號的(de)(de)(de)存(cun)儲(chu)區域。存(cun)儲(chu)區域可以是軟盤、CD、硬(ying)盤或其他類(lei)型的(de)(de)(de)磁(ci)盤。單擊“Windows資(zi)源管(guan)理器(qi)(qi)”或“我的(de)(de)(de)電腦(nao)”中相應的(de)(de)(de)圖(tu)標可以查看驅(qu)動(dong)器(qi)(qi)的(de)(de)(de)詳細內(nei)容(rong)。

驅(qu)動(dong)器(qi)(qi)在整個(ge)控(kong)制環(huan)節(jie)中(zhong)，正(zheng)好(hao)處(chu)于主控(kong)制箱(xiang)（MAIN CONTROLLER）--》驅(qu)動(dong)器(qi)(qi)（DRIVER）--》馬(ma)達(da)（MOTOR）的(de)中(zhong)間換(huan)節(jie)。驅(qu)動(dong)器(qi)(qi)的(de)主要(yao)功能(neng)是接收來自主控(kong)制箱(xiang)（NC CARD）的(de)信(xin)號，然(ran)后將信(xin)號進行處(chu)理再轉移至馬(ma)達(da)以及(ji)和馬(ma)達(da)有(you)關的(de)感應(ying)器(qi)(qi)（SENSOR），并且將馬(ma)達(da)的(de)工(gong)作情況反饋(kui)至主控(kong)制箱(xiang)（MAIN CONTROLLER）。
