電(dian)容式啟動(dong)電(dian)動(dong)機(ji)
該(gai)類電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)可(ke)分(fen)為電(dian)(dian)(dian)容(rong)分(fen)相(xiang)(xiang)(xiang)啟動(dong)(dong)電(dian)(dian)(dian)機(ji)(ji)和永久分(fen)相(xiang)(xiang)(xiang)電(dian)(dian)(dian)容(rong)電(dian)(dian)(dian)機(ji)(ji)。這種電(dian)(dian)(dian)機(ji)(ji)結構簡(jian)單、啟動(dong)(dong)快(kuai)速、轉速穩(wen)定，被廣泛應(ying)用(yong)在(zai)電(dian)(dian)(dian)風扇、排風扇、抽油煙(yan)機(ji)(ji)等家用(yong)電(dian)(dian)(dian)器(qi)中。電(dian)(dian)(dian)容(rong)分(fen)相(xiang)(xiang)(xiang)式電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)在(zai)定子(zi)繞(rao)組(zu)上設有主繞(rao)組(zu)和副繞(rao)組(zu)（啟動(dong)(dong)繞(rao)組(zu)），并(bing)在(zai)啟動(dong)(dong)繞(rao)組(zu)中串聯(lian)大容(rong)量啟動(dong)(dong)電(dian)(dian)(dian)容(rong)器(qi)，使通電(dian)(dian)(dian)后(hou)主、副繞(rao)組(zu)的電(dian)(dian)(dian)相(xiang)(xiang)(xiang)角成９０°，從而能產生較大的啟動(dong)(dong)轉矩，使轉子(zi)啟動(dong)(dong)運轉。
對于永久分相電(dian)(dian)容電(dian)(dian)動機(ji)(ji)(ji)(ji)(ji)(ji)來說(shuo)，其串接的(de)電(dian)(dian)容器，當(dang)電(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)在通電(dian)(dian)啟(qi)(qi)動或者正常運(yun)(yun)行(xing)時，均(jun)與(yu)啟(qi)(qi)動繞組串接。由于永久分相電(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)其啟(qi)(qi)動的(de)轉(zhuan)矩較小，因此很(hen)適于排風(feng)機(ji)(ji)(ji)(ji)(ji)(ji)、抽風(feng)機(ji)(ji)(ji)(ji)(ji)(ji)等要(yao)求啟(qi)(qi)動力矩低的(de)電(dian)(dian)器設備中應用。電(dian)(dian)容式啟(qi)(qi)動電(dian)(dian)動機(ji)(ji)(ji)(ji)(ji)(ji)，由于其運(yun)(yun)行(xing)繞組分正、反相繞制設定(ding)，所以只(zhi)要(yao)切換運(yun)(yun)行(xing)繞組和(he)啟(qi)(qi)動繞組的(de)串接方(fang)向，即可方(fang)便實現電(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)逆、順(shun)方(fang)向運(yun)(yun)轉(zhuan)。
