一、什(shen)么叫直(zhi)流減速電(dian)機呢？今天兆威(wei)機電(dian)就給大家介(jie)紹一下(xia)直(zhi)流減速電(dian)機的原(yuan)理，如(ru)下(xia)：

??直流減速電機就是調節直(zhi)(zhi)流電(dian)(dian)動(dong)機(ji)速度(du)(du)的(de)設備,?由于直(zhi)(zhi)流電(dian)(dian)動(dong)機(ji)具有(you)低(di)轉速大(da)力矩的(de)特點,是交流電(dian)(dian)動(dong)機(ji)無法(fa)取代的(de),?因此調節直(zhi)(zhi)流電(dian)(dian)動(dong)機(ji)速度(du)(du)的(de)設備—直(zhi)(zhi)流調速器,具有(you)廣闊的(de)應用天地(di)。

 二、什么(me)場合下要(yao)(yao)選擇使(shi)用直(zhi)流減速電機(ji)？下列場合需要(yao)(yao)使(shi)用直(zhi)流減速電機(ji)

 1,需要較寬的調速(su)范圍。

 2,需(xu)要較快(kuai)的動(dong)態響應過程。

 3,加、減速時需(xu)要自(zi)動平滑的過渡(du)過程。

 4,需要低(di)速運轉時(shi)力矩大。

 5,需要較好的(de)挖土機特(te)性，能將過載電流(liu)自(zi)動(dong)限止(zhi)在(zai)設定電流(liu)上。

 以上五點也(ye)是直流調速(su)器(qi)的應用(yong)特點。

 三、直流(liu)減速電機應用:

   直流減速(su)電機(ji)在數控機(ji)床(chuang)、造紙(zhi)印刷、紡織印染、光纜線纜設(she)備、包裝機(ji)械、電工機(ji)械、食品加工機(ji)械、橡膠機(ji)械、生物設(she)備、印制電路板設(she)備、實(shi)驗設(she)備、焊接(jie)(jie)切(qie)割、輕工機(ji)械、物流輸送設(she)備、機(ji)車(che)車(che)輛、通訊設(she)備、雷達設(she)備、衛(wei)星(xing)地(di)面(mian)接(jie)(jie)受系統等(deng)行業應用。

 四、直流減速電機工作原理簡單(dan)介紹(shao)：

   直(zhi)(zhi)流(liu)(liu)(liu)(liu)減速(su)電(dian)(dian)(dian)(dian)(dian)機(ji)就是(shi)調(diao)(diao)(diao)(diao)節直(zhi)(zhi)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)動機(ji)速(su)度(du)的設備，上端(duan)和交(jiao)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源連(lian)接(jie)，下(xia)端(duan)和直(zhi)(zhi)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)動機(ji)連(lian)接(jie)，直(zhi)(zhi)流(liu)(liu)(liu)(liu)調(diao)(diao)(diao)(diao)速(su)器將交(jiao)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)轉化成兩路輸出直(zhi)(zhi)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源，一路輸入給直(zhi)(zhi)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)機(ji)(推薦(jian):直(zhi)(zhi)流(liu)(liu)(liu)(liu)減速(su)電(dian)(dian)(dian)(dian)(dian)機(ji))礪(li)磁（定(ding)子(zi)），一路輸入給直(zhi)(zhi)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)機(ji)電(dian)(dian)(dian)(dian)(dian)樞（轉子(zi)），直(zhi)(zhi)流(liu)(liu)(liu)(liu)調(diao)(diao)(diao)(diao)速(su)器通過控制電(dian)(dian)(dian)(dian)(dian)樞直(zhi)(zhi)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)來調(diao)(diao)(diao)(diao)節直(zhi)(zhi)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)動機(ji)轉速(su)。同時直(zhi)(zhi)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)動機(ji)給調(diao)(diao)(diao)(diao)速(su)器一個反(fan)饋電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)，調(diao)(diao)(diao)(diao)速(su)器根據反(fan)饋電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)來判斷直(zhi)(zhi)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)機(ji)的轉速(su)情(qing)況，必要時修正(zheng)電(dian)(dian)(dian)(dian)(dian)樞電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)輸出，以此來再次調(diao)(diao)(diao)(diao)節電(dian)(dian)(dian)(dian)(dian)機(ji)的轉速(su)。

  五、直流電(dian)(dian)機的調速(su)方案一(yi)般有下(xia)列3種(zhong)方式(shi)：1、改變(bian)電(dian)(dian)樞電(dian)(dian)壓(ya)(ya)；2、改變(bian)激(ji)磁繞組電(dian)(dian)壓(ya)(ya)；3、改變(bian)電(dian)(dian)樞回路電(dian)(dian)阻。常(chang)用的是調壓(ya)(ya)調速(su)系(xi)統，即(ji)1（改變(bian)電(dian)(dian)樞電(dian)(dian)壓(ya)(ya)）.

? 六、一種模塊式(shi)直(zhi)流電機調速(su)(su)器(qi)(qi)，集電源(yuan)、控制(zhi)、驅動電路(lu)(lu)(lu)于一體，采用(yong)(yong)立(li)體結構(gou)布局，控制(zhi)電路(lu)(lu)(lu)采用(yong)(yong)微功耗(hao)元(yuan)件(jian)，用(yong)(yong)光電耦合(he)器(qi)(qi)提升電流、電壓的(de)隔(ge)離變換(huan)，電路(lu)(lu)(lu)的(de)比例常(chang)(chang)數、積(ji)(ji)分常(chang)(chang)數和(he)微分常(chang)(chang)數用(yong)(yong)PID適配器(qi)(qi)調整。該調速(su)(su)器(qi)(qi)體積(ji)(ji)小、重量(liang)輕，可單使用(yong)(yong)也(ye)可直(zhi)接安裝(zhuang)在直(zhi)流電機上構(gou)成一體化(hua)直(zhi)流減(jian)速(su)(su)電機，可具有調速(su)(su)器(qi)(qi)所應有的(de)一切(qie)功能(neng)。
