src="http://tyunfile.71360.com/UpLoadFile/2019/11/21/9/637099267886684512_lcdianji_8182965.jpg"></div><p 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。

看：每天**時(shí)看電動(dòng)機(jī)工作電流的大小和變化，看周圍有沒有漏水、滴水，會(huì)引起電動(dòng)機(jī)絕緣低擊穿而燒壞。還要看電動(dòng)機(jī)**是否有影響其通風(fēng)散熱環(huán)境的物件？看風(fēng)扇端蓋、扇葉和電動(dòng)機(jī)外部是否過(guò)臟需要清潔？要確保其冷卻散熱效果。無(wú)論誰(shuí)發(fā)現(xiàn)問(wèn)題，都應(yīng)及時(shí)處理。聽：認(rèn)真細(xì)聽電動(dòng)機(jī)的運(yùn)行聲音是否異常，因機(jī)房噪音較大，可借助于螺絲刀或聽棒等輔助工具，貼近電動(dòng)機(jī)兩端聽，如果經(jīng)常聽，不但能發(fā)現(xiàn)電動(dòng)機(jī)及其拖動(dòng)設(shè)備的不良振動(dòng)，連內(nèi)部軸承油的多少都能判斷，從而及時(shí)作出添加軸承油，或更換新軸承等相應(yīng)的措施處理，避免電動(dòng)機(jī)軸承缺油干磨而堵轉(zhuǎn)、走外圓、掃膛燒壞。多數(shù)廠家考慮到大型電動(dòng)機(jī)解體更換軸承的困難，會(huì)采用開式軸承，定期（2000h）用油加油時(shí)需注意使用電機(jī)**標(biāo)示軸承油（-35℃～+140℃），并將下端放油口打開或另一邊的悶頭螺絲拆卸開，以便將舊油擠換出來(lái)（注意補(bǔ)充油定額）防止加油時(shí)因壓力大把油擠到電動(dòng)機(jī)內(nèi)部，運(yùn)轉(zhuǎn)時(shí)濺到定轉(zhuǎn)子上，影響電動(dòng)機(jī)的散熱功能等。
