無刷(shua)(shua)直(zhi)流電(dian)(dian)(dian)機(ji)由電(dian)(dian)(dian)動(dong)機(ji)主體(ti)和驅動(dong)器組成，是一種典(dian)型的(de)(de)(de)機(ji)電(dian)(dian)(dian)一體(ti)化(hua)產品。由于(yu)無刷(shua)(shua)直(zhi)流電(dian)(dian)(dian)動(dong)機(ji)是以自控式運行的(de)(de)(de)，所(suo)以不會(hui)像變頻調速下重(zhong)載啟動(dong)的(de)(de)(de)同(tong)步電(dian)(dian)(dian)機(ji)那樣在轉子上(shang)另(ling)加啟動(dong)繞組，也不會(hui)在負載突變時(shi)產生振蕩和失步。中小容量的(de)(de)(de)無刷(shua)(shua)直(zhi)流電(dian)(dian)(dian)動(dong)機(ji)的(de)(de)(de)永(yong)磁體(ti)，現在多采(cai)用高磁能級的(de)(de)(de)稀(xi)土釹鐵硼(Nd-Fe-B)材料。因此(ci)，稀(xi)土永(yong)磁無刷(shua)(shua)電(dian)(dian)(dian)動(dong)機(ji)的(de)(de)(de)體(ti)積比同(tong)容量三相異步電(dian)(dian)(dian)動(dong)機(ji)縮小了一個機(ji)座(zuo)號。

1.有(you)刷電(dian)(dian)機：采用(yong)碳刷和換(huan)向(xiang)(xiang)器進行換(huan)向(xiang)(xiang)工作的電(dian)(dian)機。2.無刷電(dian)(dian)機：采用(yong)內置(zhi)(zhi)磁性(xing)傳感(gan)器檢測電(dian)(dian)機轉動(dong)到的位置(zhi)(zhi)，再輸(shu)入不(bu)(bu)同方向(xiang)(xiang)的電(dian)(dian)流(liu)進行電(dian)(dian)子換(huan)向(xiang)(xiang)，是(shi)一種比(bi)較特(te)別的直流(liu)電(dian)(dian)機。無刷電(dian)(dian)機的優點(dian)：有(you)刷電(dian)(dian)機碳刷和換(huan)向(xiang)(xiang)器之(zhi)間有(you)摩擦，很容易磨損(sun)，但是(shi)無刷電(dian)(dian)機就不(bu)(bu)存在這種情況(kuang)(kuang)，控制(zhi)器報(bao)價，它的傳感(gan)器和磁鐵之(zhi)間沒有(you)摩擦，也(ye)就不(bu)(bu)可(ke)以(yi)有(you)磨損(sun)的情況(kuang)(kuang)，所(suo)以(yi)無刷電(dian)(dian)機更耐(nai)用(yong)，現在使(shi)用(yong)范圍(wei)也(ye)比(bi)較廣泛，深受人們喜愛。
