style="text-indent:25px">三相異步電動(dòng)機(jī)由固定的定子和旋轉(zhuǎn)的轉(zhuǎn)子兩個(gè)基本部分組成，轉(zhuǎn)子裝在定子內(nèi)腔里，借助軸承被支撐在兩個(gè)端蓋上。為了保證轉(zhuǎn)子能在定子內(nèi)自由轉(zhuǎn)動(dòng)，定子和轉(zhuǎn)子之間必須有一間隙，稱為氣隙。電動(dòng)機(jī)的氣隙是一個(gè)非常重要的參數(shù)，其大小及對(duì)稱性等對(duì)電動(dòng)機(jī)的性能有很大影響。圖2所示定子由定子三相繞組、定子鐵心和機(jī)座組成。定子三相繞組是異步電動(dòng)機(jī)的電路部分，在異步電動(dòng)機(jī)的運(yùn)行中起著很重要的作用，是把電能轉(zhuǎn)換為機(jī)械能的關(guān)鍵部件。定子三相繞組的結(jié)構(gòu)是對(duì)稱的，一般有六個(gè)出線端U1、U2、V1、V2、W1、W2，置于機(jī)座外側(cè)的接線盒內(nèi)，根據(jù)需要接成星形（Y）或三角形（△），如圖3所示。圖3定子鐵心是異步電動(dòng)機(jī)磁路的一部分，由于主磁場(chǎng)以同步轉(zhuǎn)速相對(duì)定子旋轉(zhuǎn)，為減小在鐵心中引起的損耗，鐵心采用0.5mm厚的高導(dǎo)磁硅鋼片疊成，硅鋼片兩面涂有絕緣漆以減小鐵心的渦流損耗。機(jī)座又稱機(jī)殼，它的主要作用是支撐定子鐵心，同時(shí)也承受整個(gè)電動(dòng)機(jī)負(fù)載運(yùn)行時(shí)產(chǎn)生的反作用力，運(yùn)行時(shí)由于內(nèi)部損耗所產(chǎn)生的熱量也是通過(guò)機(jī)座向外散發(fā)。中、小型電動(dòng)機(jī)的機(jī)座一般采用鑄鐵制成。大型電動(dòng)機(jī)因機(jī)身較大澆注不便，常用鋼板焊接成型。為三相籠型異步電動(dòng)機(jī)的組成部件。上海電機(jī)零配件聯(lián)創(chuàng)電機(jī)有著質(zhì)量的服務(wù)質(zhì)量和極高的信用等級(jí)。</p><div

style="text-indent:25px">高壓電機(jī)可以做得功率很大，比較大可達(dá)到幾千甚至幾萬(wàn)千瓦。這是因?yàn)?，在同樣的輸出功率時(shí)，高壓電機(jī)的電流可比低壓電機(jī)小很多（基本上是與電壓成反比關(guān)系），例如500kW、4極電機(jī)的額定電流，額定電壓為380V時(shí)為900A左右，而額定電壓為10kV時(shí)只有30A左右。所以高壓電機(jī)繞組可用較小的線徑。由此，高壓電機(jī)的定子銅損耗也會(huì)比低壓電機(jī)少。對(duì)于較大功率的電機(jī)，使用低壓電時(shí)，則因需要較粗的導(dǎo)線而需要很大面積的定子槽，使定子鐵芯直徑做得很大，電機(jī)整個(gè)體積也會(huì)很大。對(duì)于較大容量的電機(jī)，高壓電機(jī)所用電源和配電設(shè)備比低壓電機(jī)的總體投資少，并且線路損耗小，可節(jié)省一定的耗電量。特別是10kV的高壓電機(jī)，可直接使用網(wǎng)絡(luò)電源（我國(guó)提供給用戶的高壓電一般都是10kV），這樣在電源設(shè)備（主要是變壓器）上的投資會(huì)更少，使用也較簡(jiǎn)便，故障率也會(huì)較少。聯(lián)創(chuàng)電機(jī)始終適應(yīng)和促進(jìn)工業(yè)發(fā)展為宗旨。北京大型高壓電機(jī)多少錢</p><p
