關于直流電機(推薦:微型直流減速電機)，之前已經介(jie)紹了(le)很多，今天為大(da)家介(jie)紹直流(liu)電機(ji)的調速系統發展史，不要(yao)錯過哦！

　直(zhi)(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)氣(qi)驅動(dong)(dong)(dong)系統(tong)(tong)中(zhong)需要有(you)(you)(you)(you)專門的(de)(de)(de)可(ke)控直(zhi)(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)源常用(yong)(yong)(yong)的(de)(de)(de)可(ke)控直(zhi)(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)源有(you)(you)(you)(you)以下幾種：，初的(de)(de)(de)直(zhi)(zhi)流(liu)(liu)(liu)調速(su)(su)(su)系統(tong)(tong)是(shi)(shi)(shi)(shi)采(cai)用(yong)(yong)(yong)恒定的(de)(de)(de)直(zhi)(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)壓向直(zhi)(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)電(dian)(dian)(dian)(dian)樞供(gong)電(dian)(dian)(dian)(dian)，通過改(gai)變(bian)電(dian)(dian)(dian)(dian)樞回(hui)路中(zhong)的(de)(de)(de)電(dian)(dian)(dian)(dian)阻(zu)來提(ti)(ti)升調速(su)(su)(su)。這種方法簡(jian)(jian)單易行，設備制造(zao)方便，價格低廉。但缺點是(shi)(shi)(shi)(shi)效率低、機(ji)(ji)(ji)(ji)(ji)械特性(xing)(xing)軟(ruan)、不能(neng)在(zai)較寬范(fan)(fan)圍內平滑調速(su)(su)(su)，所以目(mu)前(qian)少(shao)采(cai)用(yong)(yong)(yong)。第二，三十年代(dai)末，出(chu)(chu)現了發(fa)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)-電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)（也稱(cheng)為旋轉(zhuan)變(bian)流(liu)(liu)(liu)組(zu)(zu)），配合采(cai)用(yong)(yong)(yong)磁放大(da)(da)器(qi)，推(tui)薦大(da)(da)家(jia)使(shi)(shi)用(yong)(yong)(yong)深(shen)圳兆威機(ji)(ji)(ji)(ji)(ji)電(dian)(dian)(dian)(dian)生產的(de)(de)(de)微型減(jian)速(su)(su)(su)器(qi)。電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)擴大(da)(da)機(ji)(ji)(ji)(ji)(ji)、閘(zha)(zha)(zha)流(liu)(liu)(liu)管(guan)等(deng)(deng)(deng)控制器(qi)件，可(ke)獲得優良的(de)(de)(de)調速(su)(su)(su)性(xing)(xing)能(neng)，如有(you)(you)(you)(you)較寬的(de)(de)(de)調速(su)(su)(su)范(fan)(fan)圍（十比(bi)(bi)一至數十比(bi)(bi)一）、較小的(de)(de)(de)轉(zhuan)速(su)(su)(su)變(bian)化(hua)率和調速(su)(su)(su)平滑等(deng)(deng)(deng)，特別是(shi)(shi)(shi)(shi)當電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)減(jian)速(su)(su)(su)時(shi)，可(ke)以通過發(fa)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)容易地將電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)軸(zhou)上的(de)(de)(de)飛輪慣量反饋給電(dian)(dian)(dian)(dian)網(wang)，這樣(yang)，一方面可(ke)得到(dao)平滑的(de)(de)(de)制動(dong)(dong)(dong)特性(xing)(xing)，另一方面又可(ke)減(jian)少(shao)能(neng)量的(de)(de)(de)損耗，提(ti)(ti)率。但發(fa)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)、電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)調速(su)(su)(su)系統(tong)(tong)的(de)(de)(de)主(zhu)要缺點是(shi)(shi)(shi)(shi)需要增加兩臺(tai)與(yu)調速(su)(su)(su)電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)相當的(de)(de)(de)旋轉(zhuan)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)和一些輔(fu)助勵磁設備，因而(er)體(ti)積維(wei)修困難等(deng)(deng)(deng)。第三，自出(chu)(chu)現汞(gong)弧(hu)變(bian)流(liu)(liu)(liu)器(qi)后，利用(yong)(yong)(yong)汞(gong)弧(hu)變(bian)流(liu)(liu)(liu)器(qi)代(dai)替(ti)上述發(fa)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)、電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)系統(tong)(tong)，使(shi)(shi)調速(su)(su)(su)性(xing)(xing)能(neng)指標又進一步提(ti)(ti)。特別是(shi)(shi)(shi)(shi)它(ta)的(de)(de)(de)系統(tong)(tong)快速(su)(su)(su)響應(ying)性(xing)(xing)是(shi)(shi)(shi)(shi)發(fa)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)、電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)系統(tong)(tong)不能(neng)比(bi)(bi)擬的(de)(de)(de)。但是(shi)(shi)(shi)(shi)汞(gong)弧(hu)變(bian)流(liu)(liu)(liu)器(qi)仍存在(zai)一些缺點：維(wei)修還是(shi)(shi)(shi)(shi)不太方便，特別是(shi)(shi)(shi)(shi)水銀蒸汽對維(wei)護人員會造(zao)成一定的(de)(de)(de)危害等(deng)(deng)(deng)。第四，1957年上出(chu)(chu)現了只晶(jing)閘(zha)(zha)(zha)管(guan)，與(yu)其它(ta)變(bian)流(liu)(liu)(liu)元件相比(bi)(bi)，晶(jing)閘(zha)(zha)(zha)管(guan)具(ju)有(you)(you)(you)(you)許多(duo)特的(de)(de)(de)優越性(xing)(xing)，因而(er)晶(jing)閘(zha)(zha)(zha)管(guan)直(zhi)(zhi)流(liu)(liu)(liu)調速(su)(su)(su)系統(tong)(tong)立即顯(xian)示出(chu)(chu)強大(da)(da)的(de)(de)(de)生命力。由于它(ta)具(ju)有(you)(you)(you)(you)體(ti)積小、響應(ying)快、工作可(ke)靠、壽命長、維(wei)修簡(jian)(jian)便等(deng)(deng)(deng)一系列特點，采(cai)用(yong)(yong)(yong)晶(jing)閘(zha)(zha)(zha)管(guan)供(gong)電(dian)(dian)(dian)(dian)，不僅使(shi)(shi)直(zhi)(zhi)流(liu)(liu)(liu)調速(su)(su)(su)系統(tong)(tong)經濟指標上和可(ke)靠性(xing)(xing)有(you)(you)(you)(you)所提(ti)(ti)，而(er)且在(zai)技術性(xing)(xing)能(neng)上也顯(xian)示出(chu)(chu)很大(da)(da)的(de)(de)(de)優越性(xing)(xing)。在(zai)響應(ying)快速(su)(su)(su)性(xing)(xing)上，機(ji)(ji)(ji)(ji)(ji)組(zu)(zu)是(shi)(shi)(shi)(shi)秒(miao)級，而(er)晶(jing)閘(zha)(zha)(zha)管(guan)變(bian)流(liu)(liu)(liu)裝置(zhi)為毫秒(miao)級。

  從20世紀80年代中后期起，以晶閘管整流(liu)(liu)裝(zhuang)置(zhi)取代了已往的(de)直流(liu)(liu)發電(dian)機(ji)電(dian)動(dong)機(ji)組(zu)及水銀整流(liu)(liu)裝(zhuang)置(zhi)，使直流(liu)(liu)電(dian)氣驅動(dong)完(wan)成一(yi)次大的(de)躍進。同時(shi)，控制電(dian)路已經提升集成化、小型化、可靠性及低(di)成本。以上技術(shu)的(de)應用(yong)，使直流(liu)(liu)調速(su)系統的(de)性能指(zhi)標大幅提，應用(yong)范圍不斷擴大，直流(liu)(liu)調速(su)技術(shu)不斷發展。

隨著微(wei)型(xing)計(ji)算機、集成電(dian)(dian)路、電(dian)(dian)子電(dian)(dian)力(li)開關器(qi)件和(he)傳(chuan)感(gan)器(qi)的(de)出現，以及自(zi)動(dong)(dong)控(kong)制(zhi)(zhi)理論、電(dian)(dian)力(li)電(dian)(dian)子技術、計(ji)算機控(kong)制(zhi)(zhi)技術的(de)深入發(fa)展，電(dian)(dian)氣(qi)驅動(dong)(dong)裝置不(bu)斷向(xiang)前發(fa)展。微(wei)機的(de)應(ying)用使電(dian)(dian)氣(qi)驅動(dong)(dong)控(kong)制(zhi)(zhi)系統趨向(xiang)于數字化、智能化推(tui)(tui)動(dong)(dong)了(le)電(dian)(dian)氣(qi)驅動(dong)(dong)的(de)發(fa)展。近年來(lai)，一些(xie)陸續推(tui)(tui)出并大(da)量使用以微(wei)機為控(kong)制(zhi)(zhi)的(de)多(duo)種直流電(dian)(dian)氣(qi)驅動(dong)(dong)裝置，等等。
