電(dian)(dian)機(ji)(ji)(ji)由轉(zhuan)子(zi)(zi)(zi)和(he)(he)定子(zi)(zi)(zi)兩部(bu)(bu)分組(zu)成，電(dian)(dian)機(ji)(ji)(ji)轉(zhuan)子(zi)(zi)(zi)：是(shi)電(dian)(dian)機(ji)(ji)(ji)中的旋轉(zhuan)部(bu)(bu)件，它是(shi)用來完成電(dian)(dian)能與機(ji)(ji)(ji)械能和(he)(he)機(ji)(ji)(ji)械能與電(dian)(dian)能的轉(zhuan)化裝(zhuang)置。電(dian)(dian)機(ji)(ji)(ji)轉(zhuan)子(zi)(zi)(zi)分為電(dian)(dian)動機(ji)(ji)(ji)轉(zhuan)子(zi)(zi)(zi)和(he)(he)發電(dian)(dian)機(ji)(ji)(ji)轉(zhuan)子(zi)(zi)(zi)。　　

滾動方法

電(dian)機轉子分為內轉子滾(gun)(gun)動(dong)(dong)方(fang)法(fa)(fa)和外(wai)(wai)轉子滾(gun)(gun)動(dong)(dong)方(fang)法(fa)(fa)兩種。內轉子滾(gun)(gun)動(dong)(dong)方(fang)法(fa)(fa)為電(dian)機中心的芯體(ti)為旋轉體(ti)，輸出扭(niu)矩（指電(dian)動(dong)(dong)機）或者收入能(neng)量（指發電(dian)機）。外(wai)(wai)轉子滾(gun)(gun)動(dong)(dong)方(fang)法(fa)(fa)即(ji)以(yi)電(dian)機外(wai)(wai)體(ti)為旋轉體(ti)，不同的方(fang)法(fa)(fa)方(fang)便了各種場(chang)合的使用。

定子繞組類型

定子繞(rao)組根據線(xian)圈(quan)繞(rao)制的形狀(zhuang)與嵌(qian)裝布(bu)(bu)線(xian)方法不(bu)同，可分為集中式(shi)和分布(bu)(bu)式(shi)兩類。

1．集中式繞組(zu)　　

集(ji)中(zhong)式(shi)(shi)(shi)繞(rao)組使用于凸(tu)極(ji)式(shi)(shi)(shi)定(ding)子，一(yi)(yi)般繞(rao)制成矩形線圈，經(jing)紗帶包扎定(ding)型，再經(jing)浸漆烘干處理(li)后(hou)，嵌裝在凸(tu)形磁(ci)(ci)極(ji)的鐵(tie)心上。一(yi)(yi)般換向器式(shi)(shi)(shi)電(dian)動(dong)機(包括直流電(dian)機和通用電(dian)動(dong)機)的激磁(ci)(ci)線圈以及(ji)單相(xiang)罩(zhao)極(ji)式(shi)(shi)(shi)凸(tu)極(ji)電(dian)動(dong)機的主(zhu)極(ji)繞(rao)組都選(xuan)用集(ji)中(zhong)式(shi)(shi)(shi)繞(rao)組。　　集(ji)中(zhong)式(shi)(shi)(shi)繞(rao)組一(yi)(yi)般每極(ji)有一(yi)(yi)只線圈，但也有選(xuan)用庶極(ji)(隱極(ji))方法的，如框架式(shi)(shi)(shi)罩(zhao)極(ji)電(dian)動(dong)機是用一(yi)(yi)只線圈構成兩極(ji)的電(dian)動(dong)機。　　

2．分布(bu)式繞組(zu)　　

分布式(shi)(shi)繞(rao)組(zu)(zu)的(de)(de)電動機(ji)定子沒有凸形極(ji)掌，每個(ge)(ge)磁(ci)極(ji)由一(yi)個(ge)(ge)或幾個(ge)(ge)線(xian)圈(quan)按照一(yi)定的(de)(de)規律(lv)嵌裝布線(xian)組(zu)(zu)成線(xian)圈(quan)組(zu)(zu)，通電后構成不(bu)(bu)同(tong)極(ji)性(xing)的(de)(de)磁(ci)極(ji)，故(gu)也(ye)稱隱(yin)極(ji)式(shi)(shi)。根(gen)據(ju)嵌裝布線(xian)擺(bai)放(fang)方法的(de)(de)不(bu)(bu)同(tong)，分布式(shi)(shi)繞(rao)組(zu)(zu)又(you)可分為同(tong)心(xin)式(shi)(shi)和疊(die)式(shi)(shi)兩類。　　

（1）同(tong)(tong)心(xin)式(shi)繞(rao)組(zu)同(tong)(tong)心(xin)式(shi)繞(rao)組(zu)是由幾個形(xing)狀相(xiang)似但巨細不(bu)同(tong)(tong)的線圈，按同(tong)(tong)一(yi)中心(xin)位置嵌裝成回字形(xing)狀的線圈組(zu)。同(tong)(tong)心(xin)繞(rao)組(zu)可根據不(bu)同(tong)(tong)的布線方法而構成雙平面或三平面繞(rao)組(zu)。一(yi)般單(dan)相(xiang)電(dian)動機及(ji)部分小功率或大(da)跨距線圈的三相(xiang)異步電(dian)動機的定子繞(rao)組(zu)選用(yong)這種型(xing)式(shi)。　　

（2）疊(die)(die)(die)式(shi)(shi)(shi)(shi)(shi)繞(rao)(rao)組(zu)(zu)疊(die)(die)(die)式(shi)(shi)(shi)(shi)(shi)繞(rao)(rao)組(zu)(zu)一(yi)般是由形狀(zhuang)、巨細相同(tong)的線圈，分(fen)別以每(mei)槽嵌裝1個或兩(liang)個線圈邊(bian)，并(bing)在槽外端部(bu)逐一(yi)相疊(die)(die)(die)均勻分(fen)布的方法。疊(die)(die)(die)式(shi)(shi)(shi)(shi)(shi)繞(rao)(rao)組(zu)(zu)又分(fen)單層(ceng)(ceng)(ceng)疊(die)(die)(die)式(shi)(shi)(shi)(shi)(shi)和雙(shuang)層(ceng)(ceng)(ceng)疊(die)(die)(die)式(shi)(shi)(shi)(shi)(shi)兩(liang)種(zhong)。每(mei)槽只嵌入(ru)一(yi)個線圈邊(bian)的為單層(ceng)(ceng)(ceng)疊(die)(die)(die)式(shi)(shi)(shi)(shi)(shi)繞(rao)(rao)組(zu)(zu)，或稱(cheng)單疊(die)(die)(die)繞(rao)(rao)組(zu)(zu)；每(mei)槽嵌入(ru)兩(liang)個屬不同(tong)線圈組(zu)(zu)的線圈邊(bian)時(shi)是分(fen)置于槽中上、基層(ceng)(ceng)(ceng)，為雙(shuang)層(ceng)(ceng)(ceng)疊(die)(die)(die)式(shi)(shi)(shi)(shi)(shi)繞(rao)(rao)組(zu)(zu)，或稱(cheng)雙(shuang)疊(die)(die)(die)繞(rao)(rao)組(zu)(zu)。根據嵌裝布線方法變化不同(tong)，疊(die)(die)(die)式(shi)(shi)(shi)(shi)(shi)繞(rao)(rao)組(zu)(zu)又可派生出穿(chuan)插式(shi)(shi)(shi)(shi)(shi)、同(tong)心穿(chuan)插式(shi)(shi)(shi)(shi)(shi)以及單雙(shuang)層(ceng)(ceng)(ceng)混(hun)合(he)式(shi)(shi)(shi)(shi)(shi)等型式(shi)(shi)(shi)(shi)(shi)。

目(mu)前，一般功率較(jiao)大的(de)三相異步電動機定子繞(rao)組較(jiao)多(duo)選(xuan)用雙(shuang)層疊式；而(er)小電機則多(duo)用單層疊式繞(rao)組中的(de)派(pai)生型式，但很少選(xuan)用單層疊式繞(rao)組。
