起動 
1、合閘后電(dian)動(dong)(dong)機應立即(ji)(ji)起(qi)動(dong)(dong)起(qi)來，達到正常轉速(su)并平穩運行(xing)，否 則(ze)皮立即(ji)(ji)切斷電(dian)源，檢(jian)查并排除故障。 
2、起動(dong)后(hou)注(zhu)意觀察電(dian)動(dong)機(ji)(ji)傳(chuan)動(dong)裝置、負載機(ji)(ji)械、電(dian)壓表和電(dian)流表， 若有(you)異常現(xian)象應立即停機(ji)(ji)。 
3、電動(dong)機空(kong)載連續起動(dong)一般不(bu)超過4次(ci)，運行至熱(re)態停機后連續 起動(dong)不(bu)得超過2次(ci)，否則容易燒壞電動(dong)機。 
4、根據電(dian)網(wang)容量、負載(zai)大小和(he)電(dian)動機功(gong)率等(deng)，合理選擇起(qi)動方(fang)式， 較大功(gong)率電(dian)動機宜(yi)采(cai)(cai)采(cai)(cai)用一三(san)角法或降壓方(fang)式起(qi)動。 
運行 
1、電源電壓(ya)與額定電壓(ya)的偏差不(bu)超過±5%，三相電壓(ya)不(bu)平(ping)衡不(bu)超過1.5%。 
2、電(dian)(dian)動(dong)(dong)機(ji)運行(xing)電(dian)(dian)流不(bu)得超(chao)過(guo)(guo)銘牌上的額定電(dian)(dian)流，三相電(dian)(dian)流不(bu)平(ping)衡(heng)量不(bu)超(chao)過(guo)(guo)80%，否則會造成電(dian)(dian)動(dong)(dong)機(ji)發熱甚至(zhi)燒毀。 
3、用溫度(du)計測量電動機機殼表(biao)面(mian)溫度(du)應不超過80℃，軸承的溫度(du)應不超過95℃ 
4、電動機應經常保持清(qing)潔、干燥、通(tong)風(feng)良好，進風(feng)口與出(chu)風(feng)口必霜(shuang)保持暢通(tong)。 
5、運行中電(dian)動(dong)機出(chu)現(xian)冒煙、劇烈振(zhen)動(dong)、異常(chang)聲音、特殊氣味、轉速明(ming)顯下降(jiang)；負載設備出(chu)現(xian)故(gu)障；發生人(ren)身觸電(dian)時應立(li)即斷(duan)電(dian)停(ting)機。
