行(xing)業受國(guo)度經濟構造調整影響較(jiao)大(da)，近年來，傳(chuan)統產(chan)業如鋼鐵、起重、煤炭等(deng)行(xing)業等(deng)動搖較(jiao)大(da)，毛利率較(jiao)低(di)；為此，加(jia)快了電(dian)(dian)機(ji)(ji)產(chan)品的(de)晉(jin)級步伐(fa)，重點(dian)開展高效(xiao)減(jian)速電(dian)(dian)機(ji)(ji)、防(fang)爆電(dian)(dian)機(ji)(ji)、節能電(dian)(dian)機(ji)(ji)，無刷電(dian)(dian)機(ji)(ji)等(deng)產(chan)品。

應(ying)用(yong)到減(jian)速電(dian)機(ji)的行業(ye)普遍比擬擔憂的一個問題(ti)：減(jian)速電(dian)機(ji)工(gong)作異常，如電(dian)機(ji)通電(dian)不轉、工(gong)作無(wu)力，聲音大等(deng)狀況，為(wei)此，以本身的消(xiao)費經歷為(wei)大家分享幾個處(chu)置減(jian)速電(dian)機(ji)工(gong)作異常的方法。

減速電(dian)(dian)(dian)(dian)(dian)機假如呈(cheng)現工作無力、聲音增(zeng)大，首先需求(qiu)停止(zhi)變頻器(qi)輸(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)壓(ya)的(de)(de)丈(zhang)量。由于輸(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)壓(ya)和(he)輸(shu)出(chu)頻率成正(zheng)比，電(dian)(dian)(dian)(dian)(dian)壓(ya)不是(shi)一個肯定的(de)(de)值，但三相(xiang)電(dian)(dian)(dian)(dian)(dian)壓(ya)是(shi)均衡(heng)的(de)(de)。所以丈(zhang)量輸(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)壓(ya)，實踐上是(shi)丈(zhang)量三相(xiang)電(dian)(dian)(dian)(dian)(dian)壓(ya)能否均衡(heng)或(huo)斷相(xiang)。變頻器(qi)輸(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)壓(ya)不均衡(heng)，主要是(shi)某(mou)個開關(guan)(guan)橋臂(bei)開關(guan)(guan)不良或(huo)損(sun)壞，形(xing)成輸(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)壓(ya)斷相(xiang)或(huo)不均衡(heng)。

關于變(bian)頻(pin)器(qi)的(de)過電(dian)(dian)(dian)(dian)(dian)壓(ya)問題(ti)，假如沒有回饋(kui)電(dian)(dian)(dian)(dian)(dian)能(neng)(neng)，普通電(dian)(dian)(dian)(dian)(dian)壓(ya)不(bu)會(hui)超(chao)越540V，超(chao)越了(le)此值，多為變(bian)頻(pin)器(qi)產(chan)生(sheng)了(le)回饋(kui)電(dian)(dian)(dian)(dian)(dian)能(neng)(neng)。在有些場(chang)所，變(bian)頻(pin)器(qi)產(chan)生(sheng)回饋(kui)電(dian)(dian)(dian)(dian)(dian)能(neng)(neng)的(de)緣由不(bu)明顯(xian)，可(ke)將(jiang)電(dian)(dian)(dian)(dian)(dian)壓(ya)表(biao)較長時間接入(ru)，監(jian)視(shi)直流母(mu)線上的(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)，察看電(dian)(dian)(dian)(dian)(dian)壓(ya)在什(shen)么(me)時分升高，和負載的(de)運轉情況(kuang)有無對應關系等，以肯(ken)定產(chan)生(sheng)過電(dian)(dian)(dian)(dian)(dian)壓(ya)的(de)本(ben)源。

電(dian)(dian)機(ji)帶負載(zai)才能(neng)降(jiang)低。減速電(dian)(dian)機(ji)假如運用(yong)時間很長了，或電(dian)(dian)機(ji)質量不好(hao)，帶負載(zai)才能(neng)會降(jiang)低。這時電(dian)(dian)機(ji)的噪音也會比正常時大。

假如(ru)電機(ji)冷卻風扇(shan)損(sun)壞或(huo)刮擦電機(ji)外殼，電機(ji)固定不穩等(deng)。總之，若(ruo)可以做到以防(fang)為(wei)主，防(fang)預(yu)分離，針(zhen)對問題(ti)，處(chu)理問題(ti)，會有利(li)于減速電機(ji)的持(chi)久耐(nai)用。
