style="text-indent:25px">異步電動機(jī)的轉(zhuǎn)子由轉(zhuǎn)子鐵心、轉(zhuǎn)子繞組及轉(zhuǎn)軸組成。轉(zhuǎn)子鐵心也是電動機(jī)磁路的一部分，也是用硅鋼片疊成。與定子鐵心沖片不同的是，轉(zhuǎn)子鐵心沖片是在沖片的外圓上開槽，疊裝后的轉(zhuǎn)子鐵心外圓柱面上均勻地形成許多形狀相同的槽，用以放置轉(zhuǎn)子繞組。轉(zhuǎn)子繞組是異步電動機(jī)電路的另一部分，其作用為切割定子磁場，產(chǎn)生感應(yīng)電勢和電流，并在磁場作用下受力而使轉(zhuǎn)子轉(zhuǎn)動。其結(jié)構(gòu)可分為籠型繞組和繞線式繞組兩種類型。這兩種轉(zhuǎn)子各自的主要特點(diǎn)是：籠型轉(zhuǎn)子結(jié)構(gòu)簡單，制造方便，經(jīng)濟(jì)耐用；繞線式轉(zhuǎn)子結(jié)構(gòu)復(fù)雜，價格貴，但轉(zhuǎn)子回路可引入外加電阻來改善起動和調(diào)速性能。籠型轉(zhuǎn)子繞組由置于轉(zhuǎn)子槽中的導(dǎo)條和兩端的端環(huán)構(gòu)成。為節(jié)約用鋼和提高生產(chǎn)率，小功率異步電動機(jī)的導(dǎo)條和端環(huán)一般都是融化的鋁液一次澆鑄出來的；對于大功率的電動機(jī)，由于鑄鋁質(zhì)量不易保證，常用銅條插入轉(zhuǎn)子鐵心槽中，再在兩端焊上端環(huán)?；\型轉(zhuǎn)子繞組自行閉合，不必由外界電源供電，其外形像一個籠子，故稱籠型轉(zhuǎn)子。</p></p><br
