YE2電(dian)(dian)(dian)(dian)機(ji)(ji)三相(xiang)異(yi)(yi)步電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)又稱“感應(ying)電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)”，三相(xiang)異(yi)(yi)步電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)廠家(jia)，即轉(zhuan)子(zi)置于旋(xuan)轉(zhuan)磁(ci)場(chang)中，在旋(xuan)轉(zhuan)磁(ci)場(chang)的(de)作(zuo)用下(xia)，獲得一個轉(zhuan)動(dong)(dong)(dong)(dong)力(li)矩(ju)，因而轉(zhuan)子(zi)轉(zhuan)動(dong)(dong)(dong)(dong)。轉(zhuan)子(zi)是可轉(zhuan)動(dong)(dong)(dong)(dong)的(de)導體，三相(xiang)異(yi)(yi)步電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)生產廠家(jia)，通(tong)常多呈鼠(shu)籠狀。轉(zhuan)子(zi)繞組不(bu)需與(yu)(yu)其(qi)他電(dian)(dian)(dian)(dian)源(yuan)相(xiang)連，其(qi)定子(zi)電(dian)(dian)(dian)(dian)流(liu)直(zhi)接取自(zi)交流(liu)電(dian)(dian)(dian)(dian)力(li)系統；與(yu)(yu)其(qi)他電(dian)(dian)(dian)(dian)機(ji)(ji)相(xiang)比(bi)，YE2電(dian)(dian)(dian)(dian)機(ji)(ji)三相(xiang)異(yi)(yi)步電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)的(de)結構簡單，制造、使(shi)用、維(wei)護方便，運(yun)行可靠性高，重(zhong)量輕，成本低。以三相(xiang)異(yi)(yi)步電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)為例(li)，與(yu)(yu)同功率、同轉(zhuan)速(su)的(de)直(zhi)流(liu)電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)相(xiang)比(bi)，前者重(zhong)量只及后者的(de)二(er)分(fen)之一，成本僅為三分(fen)之一。

三相異步電動機繞組分(fen)類：

1：鏈式繞(rao)組(zu)鏈式繞(rao)組(zu)是(shi)由具有相同形狀和寬度的(de)(de)單層(ceng)線圈元件所組(zu)成，因其繞(rao)組(zu)端部各個線圈像套(tao)起的(de)(de)鏈環(huan)一樣而得名(ming)。單層(ceng)鏈式繞(rao)組(zu)應特別注意的(de)(de)是(shi)其線圈節距必須為奇數，否則該繞(rao)組(zu)將無(wu)法排列(lie)布(bu)置。

2：交叉(cha)鏈(lian)式繞(rao)組(zu)當每極每相槽數9為大于2的(de)奇數時(shi)鏈(lian)式繞(rao)組(zu)將無法排(pai)列(lie)布置，此(ci)時(shi)就需(xu)要采用具有單、雙線圈的(de)交叉(cha)式繞(rao)組(zu)。

3：同心式繞組(zu)(zu)在(zai)同一極(ji)相組(zu)(zu)內的(de)所有線圈圍抱同一圓心。

4：當每級(ji)每相槽數(shu)Q為大于2的偶數(shu)時則可采取交(jiao)叉同心式繞(rao)組的形式。

當(dang)我們把三(san)相(xiang)(xiang)異(yi)步(bu)(bu)電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)接上電(dian)(dian)(dian)源(yuan)使轉(zhuan)子(zi)順(shun)時針(zhen)方向進行旋(xuan)轉(zhuan)，這時對于一個物品(pin)來(lai)(lai)說(shuo)就會慢(man)慢(man)的提(ti)升(sheng)起來(lai)(lai)。當(dang)在下降的時候，威海三(san)相(xiang)(xiang)異(yi)步(bu)(bu)電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)，轉(zhuan)子(zi)導條相(xiang)(xiang)對旋(xuan)轉(zhuan)磁場的運(yun)動(dong)(dong)方向則(ze)會相(xiang)(xiang)反(fan)(fan)，轉(zhuan)子(zi)導條中(zhong)的感應電(dian)(dian)(dian)勢及電(dian)(dian)(dian)流(liu)方向也(ye)都隨著相(xiang)(xiang)反(fan)(fan)。有一點則(ze)是(shi)需要提(ti)醒(xing)，對于三(san)相(xiang)(xiang)異(yi)步(bu)(bu)電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)運(yun)行來(lai)(lai)說(shuo)，三(san)相(xiang)(xiang)異(yi)步(bu)(bu)電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)價格(ge)，定(ding)子(zi)是(shi)從電(dian)(dian)(dian)網吸(xi)取電(dian)(dian)(dian)功率，現在則(ze)變成(cheng)向電(dian)(dian)(dian)網輸出電(dian)(dian)(dian)功率，便(bian)成(cheng)為發(fa)電(dian)(dian)(dian)機(ji)(ji)運(yun)行了(le)。故這種限(xian)制(zhi)(zhi)轉(zhuan)速上升(sheng)的方法(fa)稱為發(fa)電(dian)(dian)(dian)機(ji)(ji)制(zhi)(zhi)動(dong)(dong)。
