盛華電機作為一家擁有二十余年電機生產經驗的變頻電機廠家，發現很多電機故障的原因是因為，電壓不符合要求。所以今天浙江盛華定頻變頻電動機生產廠家盤點電壓不符合要求的后果。

大家都知道，廠家在出(chu)廠是已加(jia)將(jiang)使(shi)用的額(e)定(ding)參(can)數(shu)寫(xie)在電機銘牌上，正常使(shi)用時符合這些參(can)數(shu)電機是可以穩(wen)定(ding)運行的。但是在實際使(shi)用時，有些情(qing)況會導致(zhi)電動機輸出(chu)功率(lv)過(guo)高(gao)或過(guo)低。

額(e)定(ding)(ding)端(duan)電(dian)(dian)(dian)壓(ya)(ya)額(e)定(ding)(ding)端(duan)電(dian)(dian)(dian)壓(ya)(ya)過(guo)高(gao)或(huo)過(guo)低的(de)發生變(bian)化，對電(dian)(dian)(dian)動(dong)四輪機都可以不好會(hui)影(ying)響。當額(e)定(ding)(ding)端(duan)電(dian)(dian)(dian)壓(ya)(ya)過(guo)高(gao)（多(duo)于10%上）時(shi)，鐵芯(xin)磁(ci)路呈(cheng)(cheng)現(xian)飽(bao)(bao)滿(man)狀態(tai)（會(hui)因為在(zai)設計方案產生自驅動(dong)力(li)時(shi)，在(zai)額(e)定(ding)(ding)值(zhi)(zhi)電(dian)(dian)(dian)流(liu)(liu)值(zhi)(zhi)降(jiang)下的(de)磁(ci)路大部分就在(zai)呈(cheng)(cheng)現(xian)飽(bao)(bao)滿(man)狀態(tai)點火車(che)站附近），為此，主磁(ci)通的(de)提高(gao)使(shi)激磁(ci)工作(zuo)電(dian)(dian)(dian)流(liu)(liu)值(zhi)(zhi)驟降(jiang)提高(gao)（為再加(jia)上電(dian)(dian)(dian)流(liu)(liu)值(zhi)(zhi)降(jiang)提高(gao)值(zhi)(zhi)的(de)很多(duo)倍)，為了(le)使(shi)定(ding)(ding)子工作(zuo)電(dian)(dian)(dian)流(liu)(liu)值(zhi)(zhi)提升(sheng)，自驅動(dong)力(li)溫度過(guo)熱，其(qi)志溫度超越同意值(zhi)(zhi)而毀壞(huai)。

當線電(dian)壓過(guo)低（高(gao)于5%以(yi)下的(de)）時，電(dian)動(dong)(dong)(dong)(dong)(dong)(dong)伸(shen)縮機(ji)傳動(dong)(dong)(dong)(dong)(dong)(dong)比(bi)成電(dian)壓值平(ping)米相(xiang)關(guan)增(zeng)(zeng)(zeng)漲(zhang)，幾則使再(zai)啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)傳動(dong)(dong)(dong)(dong)(dong)(dong)比(bi)增(zeng)(zeng)(zeng)漲(zhang)許多，電(dian)動(dong)(dong)(dong)(dong)(dong)(dong)伸(shen)縮機(ji)再(zai)啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)不(bu)便（再(zai)啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)比(bi)較慢甚至是(shi)于再(zai)啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)不(bu)起(qi)來(lai)(lai)來(lai)(lai)）；二則無法使用(yong)的(de)電(dian)動(dong)(dong)(dong)(dong)(dong)(dong)伸(shen)縮機(ji)，要(yao)是(shi)負債(zhai)電(dian)阻(zu)(zu)(zu)電(dian)阻(zu)(zu)(zu)保持良(liang)好不(bu)變（過(guo)載或特殊負債(zhai)電(dian)阻(zu)(zu)(zu)電(dian)阻(zu)(zu)(zu)使用(yong)時），定子(zi)和馬達轉子(zi)總(zong)要(yao)保持良(liang)好不(bu)得(de)不(bu)的(de)磁感應傳動(dong)(dong)(dong)(dong)(dong)(dong)比(bi)來(lai)(lai)穩(wen)定平(ping)衡負債(zhai)電(dian)阻(zu)(zu)(zu)電(dian)阻(zu)(zu)(zu)的(de)障礙矩。這就使得(de)定子(zi)和馬達轉子(zi)直流電(dian)提(ti)高(gao)，會(hui)容(rong)易(yi)造(zao)成會(hui)容(rong)易(yi)造(zao)成定子(zi)直流電(dian)提(ti)高(gao)，容(rong)易(yi)造(zao)成電(dian)動(dong)(dong)(dong)(dong)(dong)(dong)伸(shen)縮機(ji)電(dian)壓不(bu)穩(wen)，溫(wen)度上升增(zeng)(zeng)(zeng)加，減小電(dian)動(dong)(dong)(dong)(dong)(dong)(dong)伸(shen)縮機(ji)使用(yong)期限(xian)，甚至是(shi)于燒(shao)壞(huai)電(dian)動(dong)(dong)(dong)(dong)(dong)(dong)伸(shen)縮機(ji)。
