(1)監(jiān)視電動機的溫度。運行中的電動機都要發(fā)熱，萊蕪三相同步電機維修，其溫升不應(yīng)超過銘牌上的允許限度。電動機的絕大部分故障都會使它的定子電流增大，溫度升高，因此，如果發(fā)現(xiàn)電動機的溫度超過允許值，應(yīng)立即停機檢查，查明嚴重發(fā)熱的原因，排除故障后才可以運行。 </p><div

看：每天**時看電動機工作電流的大小和變化，看周圍有沒有漏水、滴水，會引起電動機絕緣低擊穿而燒壞。還要看電動機**是否有影響其通風(fēng)散熱環(huán)境的物件？看風(fēng)扇端蓋、扇葉和電動機外部是否過臟需要清潔？要確保其冷卻散熱效果。無論誰發(fā)現(xiàn)問題，都應(yīng)及時處理。聽：認真細聽電動機的運行聲音是否異常，因機房噪音較大，可借助于螺絲刀或聽棒等輔助工具，貼近電動機兩端聽，如果經(jīng)常聽，不但能發(fā)現(xiàn)電動機及其拖動設(shè)備的不良振動，連內(nèi)部軸承油的多少都能判斷，從而及時作出添加軸承油，或更換新軸承等相應(yīng)的措施處理，避免電動機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機解體更換軸承的困難，會采用開式軸承，定期（2000h）用油加油時需注意使用電機**標示軸承油（-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（注意補充油定額）防止加油時因壓力大把油擠到電動機內(nèi)部，運轉(zhuǎn)時濺到定轉(zhuǎn)子上，影響電動機的散熱功能等。

src="http://tyunfile.71360.com/UpLoadFile/2019/11/21/9/637099268088123819_lcdianji_7395067.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。
