如今家(jia)電行業的(de)普及率來越高(gao)，許(xu)多商(shang)家(jia)不僅在價格(ge)和(he)(he)性(xing)能上(shang)大(da)做文(wen)章，還在小細節(jie)上(shang)也打起了廣告，導致競爭異常(chang)激(ji)烈，其中最(zui)多的(de)便是對于有刷(shua)電機(ji)和(he)(he)無刷(shua)電機(ji)的(de)宣傳，那有刷(shua)和(he)(he)無刷(shua)的(de)區(qu)別到底在哪里(li)呢?下面(mian)無(wu)刷電(dian)機控制板廠家(jia)就為您解答(da)一番。

1、無(wu)刷電機是由電動(dong)機主體和控制板組成，是一(yi)種典型的(de)機電一(yi)體化產品。由于無(wu)刷直流電動(dong)機是以自控式運行的(de)，不(bu)會象變(bian)(bian)頻調速(su)下重載啟動(dong)的(de)同步電機那樣(yang)在轉子上另加啟動(dong)繞(rao)組，也不(bu)會在負載突(tu)變(bian)(bian)時產生(sheng)振蕩和失步。

　　2、有(you)刷(shua)(shua)(shua)電(dian)(dian)(dian)機(ji)電(dian)(dian)(dian)機(ji)工作時，線圈(quan)和(he)換向器(qi)旋(xuan)轉，磁鋼(gang)和(he)碳刷(shua)(shua)(shua)不轉，線圈(quan)電(dian)(dian)(dian)流(liu)方(fang)向的(de)交替變化(hua)是隨電(dian)(dian)(dian)機(ji)轉動(dong)的(de)換相器(qi)和(he)電(dian)(dian)(dian)刷(shua)(shua)(shua)來完成的(de)。在電(dian)(dian)(dian)動(dong)車(che)行業有(you)刷(shua)(shua)(shua)電(dian)(dian)(dian)機(ji)分高速有(you)刷(shua)(shua)(shua)電(dian)(dian)(dian)機(ji)和(he)低速有(you)刷(shua)(shua)(shua)電(dian)(dian)(dian)機(ji)。有(you)刷(shua)(shua)(shua)電(dian)(dian)(dian)機(ji)和(he)無(wu)刷(shua)(shua)(shua)電(dian)(dian)(dian)機(ji)有(you)很(hen)多區別，從(cong)名(ming)字上可以(yi)看出(chu)有(you)刷(shua)(shua)(shua)電(dian)(dian)(dian)機(ji)有(you)碳刷(shua)(shua)(shua)，無(wu)刷(shua)(shua)(shua)電(dian)(dian)(dian)機(ji)沒(mei)有(you)碳刷(shua)(shua)(shua)。

　　3、有刷(shua)電(dian)機(ji)是傳(chuan)統(tong)產品(pin)，性能比(bi)較(jiao)穩定(ding)。無(wu)(wu)刷(shua)電(dian)機(ji)是升級(ji)產品(pin)，其壽(shou)命性能比(bi)有刷(shua)電(dian)機(ji)好。但(dan)其控(kong)制(zhi)電(dian)路比(bi)較(jiao)復雜，對(dui)元件的老化篩選(xuan)要求比(bi)較(jiao)嚴(yan)(yan)格。雖然電(dian)機(ji)壽(shou)命長(chang)但(dan)控(kong)制(zhi)電(dian)路容易出毛病。因此選(xuan)用無(wu)(wu)刷(shua)電(dian)機(ji)要經(jing)過嚴(yan)(yan)格的可靠性試驗以確(que)保質量。，但(dan)是隨著技術的不斷升級(ji)幾步(bu)，無(wu)(wu)刷(shua)電(dian)機(ji)技術已經(jing)相當(dang)成熟。

　　4、在實際生產過程中(zhong)，由于有刷(shua)(shua)有齒直(zhi)流電(dian)(dian)(dian)機是高速電(dian)(dian)(dian)機，齒輪的齒很小，易磨(mo)損，但(dan)(dan)力量大，爬坡(po)能力強。而無(wu)(wu)刷(shua)(shua)直(zhi)流電(dian)(dian)(dian)機，在使(shi)用過程中(zhong)省(sheng)去了二、三年換(huan)碳刷(shua)(shua)的麻煩(fan)。但(dan)(dan)由于在控制無(wu)(wu)刷(shua)(shua)電(dian)(dian)(dian)機的過程，要求精(jing)度極高。而且(qie)，無(wu)(wu)刷(shua)(shua)電(dian)(dian)(dian)機控制器的價錢(qian)也較高。相(xiang)比之下(xia)有刷(shua)(shua)無(wu)(wu)齒的直(zhi)流電(dian)(dian)(dian)機，雖然要更換(huan)碳刷(shua)(shua)，但(dan)(dan)更換(huan)碳刷(shua)(shua)是十分(fen)容易的，而且(qie)電(dian)(dian)(dian)機的控制較為簡單，電(dian)(dian)(dian)機運轉平穩，安全(quan)系數高。

　　5、有刷(shua)電(dian)(dian)機(ji)是(shi)電(dian)(dian)機(ji)是(shi)直流(liu)電(dian)(dian)輸(shu)入，控制(zhi)它(ta)的控制(zhi)器(qi)(qi)(qi)(qi)只(zhi)給它(ta)提供(gong)大小電(dian)(dian)流(liu)就可以調(diao)速了;而(er)無刷(shua)電(dian)(dian)機(ji)其實(shi)就是(shi)個三相(xiang)交流(liu)電(dian)(dian)機(ji)，靠控制(zhi)器(qi)(qi)(qi)(qi)把直流(liu)電(dian)(dian)轉(zhuan)(zhuan)換成三相(xiang)交流(liu)電(dian)(dian)，并根據電(dian)(dian)機(ji)里(li)的傳感器(qi)(qi)(qi)(qi)霍爾元件進行換相(xiang)使電(dian)(dian)機(ji)正常運轉(zhuan)(zhuan)。直接來說，無刷(shua)電(dian)(dian)機(ji)比(bi)有刷(shua)電(dian)(dian)機(ji)壽命長、起步有勁(jing)省電(dian)(dian)，但是(shi)控制(zhi)器(qi)(qi)(qi)(qi)卻比(bi)有刷(shua)控制(zhi)器(qi)(qi)(qi)(qi)成本高(gao)。目前，現在的都是(shi)無刷(shua)控制(zhi)器(qi)(qi)(qi)(qi)，有刷(shua)電(dian)(dian)機(ji)基本在市(shi)場上淘汰了。
