電機電流高的主要原因是機械和電氣故障，如振動電機和外部物體之間的運行摩擦、軸承堵塞、老化、損壞、缺少不耐高溫的油或油脂等。過載會導致電機功率允許范圍之外的過載，特別是軸承的損壞容易引起轉子和定子之間的摩擦，如果在這種狀態下不及時處理，會導致電機線包燒毀。

　　電(dian)(dian)(dian)(dian)(dian)氣部分的(de)(de)(de)(de)原因要(yao)復雜(za)得多:電(dian)(dian)(dian)(dian)(dian)壓(ya)不(bu)(bu)穩(wen)定(過低或過高(gao))、缺相、電(dian)(dian)(dian)(dian)(dian)機(ji)線(xian)圈的(de)(de)(de)(de)相間(jian)或匝(za)間(jian)短路、三相電(dian)(dian)(dian)(dian)(dian)壓(ya)不(bu)(bu)平(ping)衡差異過大、電(dian)(dian)(dian)(dian)(dian)線(xian)涂層和接(jie)地絕緣處理不(bu)(bu)全(quan)、電(dian)(dian)(dian)(dian)(dian)纜不(bu)(bu)匹配、發熱和接(jie)頭松動(dong)。電(dian)(dian)(dian)(dian)(dian)源故障(zhang)分析:如果(guo)電(dian)(dian)(dian)(dian)(dian)機(ji)轉(zhuan)動(dong)平(ping)穩(wen)，軸(zhou)承不(bu)(bu)發熱，很可能是電(dian)(dian)(dian)(dian)(dian)氣故障(zhang)。電(dian)(dian)(dian)(dian)(dian)機(ji)安(an)裝方便，效果(guo)顯著，逐漸被電(dian)(dian)(dian)(dian)(dian)力(li)、冶金、煤炭、礦山、干燥等行(xing)業(ye)所接(jie)受，但振(zhen)動(dong)電(dian)(dian)(dian)(dian)(dian)機(ji)的(de)(de)(de)(de)使用(yong)(yong)壽(shou)(shou)命一直(zhi)是困(kun)擾用(yong)(yong)戶(hu)的(de)(de)(de)(de)一個問(wen)題。然而，只要(yao)振(zhen)動(dong)電(dian)(dian)(dian)(dian)(dian)機(ji)適當的(de)(de)(de)(de)維護(hu)，振(zhen)動(dong)電(dian)(dian)(dian)(dian)(dian)機(ji)的(de)(de)(de)(de)使用(yong)(yong)壽(shou)(shou)命將大大提(ti)高(gao)。由(you)于不(bu)(bu)同行(xing)業(ye)的(de)(de)(de)(de)工作(zuo)環境不(bu)(bu)同，振(zhen)動(dong)電(dian)(dian)(dian)(dian)(dian)機(ji)的(de)(de)(de)(de)日(ri)常維護(hu)也不(bu)(bu)同。養(yang)成對振(zhen)動(dong)電(dian)(dian)(dian)(dian)(dian)機(ji)進行(xing)例行(xing)檢查的(de)(de)(de)(de)習慣，或定期更(geng)換維護(hu)非常重要(yao)，這樣可以(yi)大大提(ti)高(gao)振(zhen)動(dong)電(dian)(dian)(dian)(dian)(dian)機(ji)的(de)(de)(de)(de)使用(yong)(yong)壽(shou)(shou)命，減少(shao)不(bu)(bu)必(bi)要(yao)的(de)(de)(de)(de)損(sun)失。

通常電動機有以下檢查方法:

　　1)靜(jing)態(tai)檢查:設備運轉前，用錘(chui)子敲打(da)振(zhen)動電(dian)機的基礎螺絲，看(kan)是否松動。未能及時擰緊將導致(zhi)振(zhen)動電(dian)機的基礎斷(duan)裂和外殼(ke)報(bao)廢。

　　2)動態(tai)檢查(cha):傾聽振動電機運轉時是否有(you)噪音(yin)。如(ru)有(you)異(yi)常噪音(yin)，應及時停車(che)，主要檢查(cha)基礎、防護罩、快速偏心和端(duan)蓋螺栓，防止松動。

　　3)溫(wen)度檢查:用溫(wen)度計或(huo)手背(bei)(小心(xin)燒傷)檢查振動電(dian)機外殼、端蓋(軸(zhou)承室在里面)和電(dian)纜的(de)溫(wen)度。振動電(dian)機本身的(de)允許溫(wen)升(sheng)為60度，加上(shang)環境(jing)溫(wen)度在正常溫(wen)度范圍內。如果溫(wen)度過(guo)高(超過(guo)90度)，檢查軸(zhou)承是(shi)否(fou)缺油(3號殼鋰(li)脂)，電(dian)壓是(shi)否(fou)過(guo)高，電(dian)纜接頭(tou)是(shi)否(fou)松動，電(dian)纜是(shi)否(fou)匹配。
