無刷電(dian)(dian)(dian)(dian)(dian)機：無刷直(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)機由(you)(you)(you)電(dian)(dian)(dian)(dian)(dian)動(dong)機主(zhu)體(ti)(ti)和(he)驅動(dong)器(qi)(qi)組成，是(shi)一種典型的(de)(de)(de)機電(dian)(dian)(dian)(dian)(dian)一體(ti)(ti)化產品。由(you)(you)(you)于無刷直(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)動(dong)機是(shi)以自控式運行的(de)(de)(de)，所(suo)以不(bu)會(hui)像(xiang)變頻調速(su)下重載啟動(dong)的(de)(de)(de)同步電(dian)(dian)(dian)(dian)(dian)機那樣(yang)在轉(zhuan)子(zi)上另加啟動(dong)繞(rao)組，也不(bu)會(hui)在負載突變時產生(sheng)振蕩和(he)失步。無刷直(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)動(dong)機是(shi)采用(yong)(yong)半導體(ti)(ti)開(kai)關(guan)器(qi)(qi)件來實現電(dian)(dian)(dian)(dian)(dian)子(zi)換(huan)向(xiang)(xiang)的(de)(de)(de)，即用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)子(zi)開(kai)關(guan)器(qi)(qi)件代替傳(chuan)(chuan)統的(de)(de)(de)接觸(chu)式換(huan)向(xiang)(xiang)器(qi)(qi)和(he)電(dian)(dian)(dian)(dian)(dian)刷。它具有(you)可(ke)靠性高、無換(huan)向(xiang)(xiang)火花、機械噪聲低(di)等優點(dian)，廣泛應用(yong)(yong)于高檔錄音座、錄像(xiang)機、電(dian)(dian)(dian)(dian)(dian)子(zi)儀器(qi)(qi)及自動(dong)化辦公設備中。無刷直(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)動(dong)機由(you)(you)(you)永(yong)磁體(ti)(ti)轉(zhuan)子(zi)、多極繞(rao)組定(ding)(ding)子(zi)、位(wei)(wei)(wei)置(zhi)傳(chuan)(chuan)感器(qi)(qi)等組成。位(wei)(wei)(wei)置(zhi)傳(chuan)(chuan)感按轉(zhuan)子(zi)位(wei)(wei)(wei)置(zhi)的(de)(de)(de)變化，沿著一定(ding)(ding)次序對(dui)定(ding)(ding)子(zi)繞(rao)組的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)進行換(huan)流(liu)(liu)(liu)（即檢測轉(zhuan)子(zi)磁極相對(dui)定(ding)(ding)子(zi)繞(rao)組的(de)(de)(de)位(wei)(wei)(wei)置(zhi)，并在確定(ding)(ding)的(de)(de)(de)位(wei)(wei)(wei)置(zhi)處(chu)產生(sheng)位(wei)(wei)(wei)置(zhi)傳(chuan)(chuan)感信號，經信號轉(zhuan)換(huan)電(dian)(dian)(dian)(dian)(dian)路(lu)處(chu)理后去控制功率開(kai)關(guan)電(dian)(dian)(dian)(dian)(dian)路(lu)，按一定(ding)(ding)的(de)(de)(de)邏輯關(guan)系進行繞(rao)組電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)切換(huan)）。

無刷電機(ji)優(you)點：無電刷、低干(gan)擾(rao)、噪音低、運轉順暢、壽命長、低維護成本；

無刷電機缺點：摩擦大、損耗大、發熱(re)大、壽命短、效(xiao)率(lv)低、輸出功(gong)率(lv)小；

無刷電(dian)機(ji)：通常被使用在控制(zhi)要求比較高(gao)(gao)，轉速(su)比較高(gao)(gao)的(de)設備上，如航模，精(jing)密儀器(qi)儀表等對電(dian)機(ji)轉速(su)控制(zhi)嚴格(ge)，轉速(su)達(da)到很高(gao)(gao)的(de)設備上。

普通(tong)電(dian)(dian)機：普通(tong)電(dian)(dian)機通(tong)俗(su)點講就(jiu)是(shi)驅動器，它(ta)是(shi)動力的主要來(lai)源，沒有(you)減速功能，它(ta)是(shi)把電(dian)(dian)能轉換成機械(xie)能的一(yi)種設備，它(ta)可以利用通(tong)電(dian)(dian)線圈（也就(jiu)是(shi)定子繞組）產生旋轉磁(ci)場，并作(zuo)用于轉子（如鼠籠式閉(bi)合鋁框）形成磁(ci)電(dian)(dian)動力旋轉扭(niu)矩(ju)。電(dian)(dian)機俗(su)稱“馬達”。普通(tong)電(dian)(dian)機分類：

1.直(zhi)流(liu)電(dian)動機按結構及工作原理可劃分：無刷直(zhi)流(liu)電(dian)動機和有刷直(zhi)流(liu)電(dian)動機。

2.有(you)刷直流(liu)電(dian)動(dong)機可劃分(fen)：永磁直流(liu)電(dian)動(dong)機和電(dian)磁直流(liu)電(dian)動(dong)機。

3.電(dian)(dian)磁直流(liu)電(dian)(dian)動(dong)機(ji)劃分(fen)：串勵(li)直流(liu)電(dian)(dian)動(dong)機(ji)、并勵(li)直流(liu)電(dian)(dian)動(dong)機(ji)、他勵(li)直流(liu)電(dian)(dian)動(dong)機(ji)和復勵(li)直流(liu)電(dian)(dian)動(dong)機(ji)。

4.永(yong)磁(ci)直流(liu)電(dian)(dian)動機(ji)劃(hua)分：稀土永(yong)磁(ci)直流(liu)電(dian)(dian)動機(ji)、鐵氧(yang)體永(yong)磁(ci)直流(liu)電(dian)(dian)動機(ji)和鋁鎳鈷(gu)永(yong)磁(ci)直流(liu)電(dian)(dian)動機(ji)。
