電機是生產(chǎn)、制造中比不可少的設(shè)備之一，為了保證電機正常工作，除了按操作規(guī)程正常使用、運行過程中注意正常監(jiān)視和維護(hù)外，還應(yīng)該進(jìn)行定期檢查，做好電機維護(hù)保養(yǎng)工作。對于新安裝的電動機定子絕緣電阻應(yīng)大于2MΩ，轉(zhuǎn)子絕緣電阻應(yīng)大于0.8MΩ；對使用中的電動機，定子絕緣電阻應(yīng)大于0.5MΩ，轉(zhuǎn)子絕緣電阻大于0.5MΩ;如達(dá)不到一標(biāo)準(zhǔn)，應(yīng)拆下來干燥；在烘干情況（50~70）定子絕緣電阻達(dá)1MΩ，轉(zhuǎn)子絕緣電阻應(yīng)大于0.5MΩ。我們的機械設(shè)備能否正常工作，很重要的一部分就在于電機能否正常運轉(zhuǎn)。所以電機保養(yǎng)也是很重要的，很多人總是不注意保養(yǎng)或者不知道怎么保養(yǎng)，等到電機出現(xiàn)問題了，電機只能維修了，維修的話既要花錢，還耽誤工作。才后悔之前沒有做好保養(yǎng)。保養(yǎng)也是一門大學(xué)問。

src="http://tyunfile.71360.com/UpLoadFile/2019/11/21/9/637099267902270512_lcdianji_8897764.jpg"></div><p style="text-indent:25px">三相異步電動機由固定的定子和旋轉(zhuǎn)的轉(zhuǎn)子兩個基本部分組成，轉(zhuǎn)子裝在定子內(nèi)腔里，借助軸承被支撐在兩個端蓋上。為了保證轉(zhuǎn)子能在定子內(nèi)自由轉(zhuǎn)動，定子和轉(zhuǎn)子之間必須有一間隙，稱為氣隙。電動機的氣隙是一個非常重要的參數(shù)，其大小及對稱性等對電動機的性能有很大影響。圖2所示定子由定子三相繞組、定子鐵心和機座組成。定子三相繞組是異步電動機的電路部分，在異步電動機的運行中起著很重要的作用，是把電能轉(zhuǎn)換為機械能的關(guān)鍵部件。定子三相繞組的結(jié)構(gòu)是對稱的，一般有六個出線端U1、U2、V1、V2、W1、W2，置于機座外側(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機磁路的一部分，由于主磁場以同步轉(zhuǎn)速相對定子旋轉(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。機座又稱機殼，它的主要作用是支撐定子鐵心，同時也承受整個電動機負(fù)載運行時產(chǎn)生的反作用力，運行時由于內(nèi)部損耗所產(chǎn)生的熱量也是通過機座向外散發(fā)。中、小型電動機的機座一般采用鑄鐵制成。大型電動機因機身較大澆注不便，常用鋼板焊接成型。為三相籠型異步電動機的組成部件。
