起動 
1、合閘后電(dian)動機應立(li)即起(qi)動起(qi)來(lai)，達到(dao)正常轉速并平穩運行，否 則皮(pi)立(li)即切(qie)斷(duan)電(dian)源，檢查(cha)并排(pai)除(chu)故障。 
2、起動(dong)后注(zhu)意觀察電(dian)動(dong)機(ji)傳動(dong)裝置、負載機(ji)械、電(dian)壓(ya)表和(he)電(dian)流(liu)表， 若有異常現(xian)象應立(li)即停機(ji)。 
3、電動(dong)機空載連(lian)(lian)續(xu)起動(dong)一般不超過4次，運(yun)行至(zhi)熱態停機后連(lian)(lian)續(xu) 起動(dong)不得超過2次，否則容易燒壞電動(dong)機。 
4、根(gen)據電(dian)網容量、負載大(da)小(xiao)和電(dian)動(dong)機(ji)功率(lv)等，合理選擇起(qi)(qi)動(dong)方式， 較大(da)功率(lv)電(dian)動(dong)機(ji)宜(yi)采采用(yong)一(yi)三角(jiao)法或(huo)降壓方式起(qi)(qi)動(dong)。 
運行 
1、電(dian)源(yuan)電(dian)壓與額定電(dian)壓的偏(pian)差不超過(guo)±5%，三相電(dian)壓不平衡(heng)不超過(guo)1.5%。 
2、電(dian)(dian)動(dong)機(ji)運行電(dian)(dian)流(liu)不(bu)得超過銘牌(pai)上的額定(ding)電(dian)(dian)流(liu)，三相(xiang)電(dian)(dian)流(liu)不(bu)平衡量不(bu)超過80%，否則(ze)會(hui)造成電(dian)(dian)動(dong)機(ji)發熱甚(shen)至燒毀。 
3、用(yong)溫度(du)(du)計測量電動機機殼(ke)表面溫度(du)(du)應(ying)不超過80℃，軸承的(de)溫度(du)(du)應(ying)不超過95℃ 
4、電動機應(ying)經(jing)常保(bao)持(chi)清潔、干燥、通風良好，進風口(kou)與(yu)出風口(kou)必霜保(bao)持(chi)暢(chang)通。 
5、運行(xing)中電(dian)動(dong)機(ji)出現(xian)冒煙、劇烈振動(dong)、異常聲(sheng)音、特殊氣味、轉速明顯下降(jiang)；負載設備出現(xian)故障(zhang)；發生人身觸電(dian)時(shi)應立即斷(duan)電(dian)停機(ji)。
