單相(xiang)異步(bu)電(dian)(dian)機(ji)是指用單相(xiang)交(jiao)流(liu)電(dian)(dian)源（AC220V）供電(dian)(dian)的(de)(de)(de)(de)小功(gong)(gong)率單相(xiang)異步(bu)電(dian)(dian)機(ji)，它(ta)的(de)(de)(de)(de)功(gong)(gong)率設計的(de)(de)(de)(de)都(dou)是比較小，一(yi)般(ban)均不會大于(yu)(yu)2kW。由(you)于(yu)(yu)電(dian)(dian)機(ji)的(de)(de)(de)(de)輸出功(gong)(gong)率不大，電(dian)(dian)機(ji)的(de)(de)(de)(de)轉(zhuan)子(zi)(zi)(zi)采用鼠籠型轉(zhuan)子(zi)(zi)(zi)，它(ta)的(de)(de)(de)(de)定子(zi)(zi)(zi)都(dou)有一(yi)套(tao)(tao)工作繞(rao)(rao)(rao)組(zu)，稱為(wei)主繞(rao)(rao)(rao)級，它(ta)在(zai)電(dian)(dian)動(dong)(dong)機(ji)的(de)(de)(de)(de)氣(qi)隙(xi)中(zhong)，只能(neng)(neng)產(chan)(chan)生(sheng)(sheng)(sheng)正(zheng)，負(fu)交(jiao)變(bian)的(de)(de)(de)(de)脈振磁(ci)場(chang)(chang)，不能(neng)(neng)產(chan)(chan)生(sheng)(sheng)(sheng)旋轉(zhuan)磁(ci)場(chang)(chang)，因(yin)此，也就不能(neng)(neng)產(chan)(chan)生(sheng)(sheng)(sheng)起動(dong)(dong)轉(zhuan)矩。為(wei)了(le)使電(dian)(dian)動(dong)(dong)機(ji)氣(qi)隙(xi)中(zhong)能(neng)(neng)產(chan)(chan)生(sheng)(sheng)(sheng)旋轉(zhuan)磁(ci)場(chang)(chang)，還需要有套(tao)(tao)輔助繞(rao)(rao)(rao)組(zu)，稱為(wei)副繞(rao)(rao)(rao)組(zu)，由(you)于(yu)(yu)副繞(rao)(rao)(rao)組(zu)產(chan)(chan)生(sheng)(sheng)(sheng)的(de)(de)(de)(de)磁(ci)場(chang)(chang)與主繞(rao)(rao)(rao)組(zu)的(de)(de)(de)(de)磁(ci)場(chang)(chang)在(zai)電(dian)(dian)動(dong)(dong)機(ji)氣(qi)隙(xi)中(zhong)合成交(jiao)產(chan)(chan)生(sheng)(sheng)(sheng)旋轉(zhuan)磁(ci)場(chang)(chang)，此時電(dian)(dian)動(dong)(dong)機(ji)交(jiao)產(chan)(chan)生(sheng)(sheng)(sheng)起動(dong)(dong)轉(zhuan)矩，因(yin)此，電(dian)(dian)動(dong)(dong)機(ji)的(de)(de)(de)(de)轉(zhuan)子(zi)(zi)(zi)才能(neng)(neng)夠自行轉(zhuan)動(dong)(dong)起來。
