山東盛華電機廠家，作為一個有著20余(yu)年生產(chan)經驗的高壓電(dian)機(ji)工作加工廠，今天(tian)為大(da)家盤點伺服電(dian)機(ji)運行中需要注意的問題。

盛(sheng)華減速(su)機服務商根據售后經驗(yan)分析(xi)，導致(zhi)電機損壞的原(yuan)因有以(yi)下兩(liang)點。

1、拆換電機(ji)的(de)聯軸(zhou)器(qi)，可聯軸(zhou)器(qi)安裝使用不好確造或加(jia)脂脂不一(yi)適，產生(sheng)軸(zhou)和軸(zhou)承套發生(sheng)振動，使軸(zhou)受損嚴峻而燒(shao)壞。

2、定子線圈磨(mo)損。主要的其原因是(shi)交(jiao)流電動機(ji)過載保護、匝間、之間、跳閘(zha)、對地損害等(deng)導致的定子線圈磨(mo)損。

盛華三(san)(san)相(xiang)減(jian)(jian)速(su)機建議大家(jia)，三(san)(san)相(xiang)減(jian)(jian)速(su)機效(xiao)率關(guan)鍵性，僅是平(ping)日維保(bao)(bao)(bao)保(bao)(bao)(bao)養也(ye)很關(guan)鍵性，經(jing)常性的維保(bao)(bao)(bao)保(bao)(bao)(bao)養三(san)(san)相(xiang)減(jian)(jian)速(su)機，實(shi)際上能持續增長電動機的選用(yong)(yong)使用(yong)(yong)時間，還能防范(fan)于未然為(wei)公司企業才能減(jian)(jian)少三(san)(san)相(xiang)減(jian)(jian)速(su)機系(xi)統故(gu)障生成(cheng)的消耗。

首先盛華同步電機加工廠提(ti)醒，考慮到(dao)逃避和(he)(he)以減少三相(xiang)馬(ma)(ma)達馬(ma)(ma)達電(dian)(dian)源異步(bu)直流(liu)(liu)(liu)電(dian)(dian)驅(qu)力(li)陡(dou)然(ran)順壞(huai)責任事故，三相(xiang)馬(ma)(ma)達馬(ma)(ma)達電(dian)(dian)源異步(bu)直流(liu)(liu)(liu)電(dian)(dian)驅(qu)力(li)需要整(zheng)存整(zheng)取(qu)的(de)(de)保養和(he)(he)觀(guan)(guan)察(cha)維(wei)修(xiu)。如遇有直流(liu)(liu)(liu)電(dian)(dian)驅(qu)力(li)溫度過高和(he)(he)定(ding)子馬(ma)(ma)達定(ding)子絕緣性太低(di)時，須(xu)直接做(zuo)好觀(guan)(guan)察(cha)維(wei)修(xiu)。三相(xiang)馬(ma)(ma)達馬(ma)(ma)達電(dian)(dian)源異步(bu)直流(liu)(liu)(liu)電(dian)(dian)驅(qu)力(li)的(de)(de)觀(guan)(guan)察(cha)維(wei)修(xiu)的(de)(de)方法(fa)是：將直流(liu)(liu)(liu)電(dian)(dian)驅(qu)力(li)做(zuo)好拆(chai)解，對(dui)各機件先做(zuo)好做(zuo)好清理，再對(dui)它們的(de)(de)作表觀(guan)(guan)觀(guan)(guan)察(cha)，可不可以有錯(cuo)誤。最后對(dui)重中之重部件的(de)(de)長度做(zuo)好測試，對(dui)馬(ma)(ma)達馬(ma)(ma)達定(ding)子作電(dian)(dian)氣設備觀(guan)(guan)察(cha)。
