德國進(jìn)口Meto-Fer配件AS12/60來這里
電機(jī)過載運(yùn)行，使電流增加，轉(zhuǎn)速降低，耗損加大。繞組接線錯(cuò)誤或發(fā)生短路時(shí)，均會(huì)使電動(dòng)機(jī)過熱而損壞，為了避免電機(jī)燒毀，在運(yùn)行中的電動(dòng)機(jī)應(yīng)進(jìn)行必要的監(jiān)測：電源電壓變化情況。與額定值偏差不超過正負(fù)百分之五。三相電壓不平衡度不大于正負(fù)百分之五。常檢查電機(jī)三相電流是否平衡。其三相電流任何一相電流與其他兩相電流平均值差不超過1%；如果超過則表明電機(jī)有故障，應(yīng)保持在額定電流下運(yùn)行。觀察電機(jī)有無振動(dòng)，噪音和異常氣味。
