YE2電(dian)(dian)機與單相異(yi)步(bu)電(dian)(dian)動機相比，運行性(xing)能較好(hao)。按照轉子結構不同，可分為籠式和繞(rao)線式兩種。籠式轉子的異(yi)步(bu)電(dian)(dian)動機結構簡單、運行可靠、重量輕、價格便(bian)宜，YE2電(dian)(dian)機定制(zhi)廠家，得到了廣(guang)泛的應(ying)用，YE2電(dian)(dian)機生產(chan)廠家，其主要缺點是調速困難(nan)。繞(rao)線式三相異(yi)步(bu)電(dian)(dian)動機的轉子和定子一(yi)樣也設置(zhi)了三相繞(rao)組并通過滑環、電(dian)(dian)刷(shua)與外部變阻器連接(jie)。如(ru)果(guo)您(nin)想要了解更多產(chan)品(pin)資(zi)訊，或者任何問題，都歡迎您(nin)與我(wo)們聯系(xi)。

設備(bei)電機(ji)的運行(xing)中的故障處理(li)

啟(qi)動(dong)(dong)(dong)(dong)時的故障，當合上(shang)斷(duan)(duan)路(lu)器或(huo)自動(dong)(dong)(dong)(dong)開關(guan)后，電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)不(bu)(bu)轉(zhuan)(zhuan)(zhuan)(zhuan)，YE2電(dian)(dian)(dian)機(ji)(ji)批(pi)發(fa)，只聽到(dao)嗡嗡的聲響，或(huo)者不(bu)(bu)能(neng)轉(zhuan)(zhuan)(zhuan)(zhuan)到(dao)全速，這種故障原因可能(neng)是： ?定子回路(lu)一(yi)相斷(duan)(duan)線，如(ru)低壓(ya)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)熔(rong)斷(duan)(duan)器一(yi)相熔(rong)斷(duan)(duan)，或(huo)高壓(ya)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)短路(lu)器以(yi)及隔(ge)離(li)開關(guan)的一(yi)相接觸不(bu)(bu)良，不(bu)(bu)能(neng)形成三相旋(xuan)轉(zhuan)(zhuan)(zhuan)(zhuan)磁場(chang)。 ?轉(zhuan)(zhuan)(zhuan)(zhuan)子回路(lu)斷(duan)(duan)線或(huo)接觸不(bu)(bu)良，使轉(zhuan)(zhuan)(zhuan)(zhuan)子繞組內無(wu)電(dian)(dian)(dian)流或(huo)電(dian)(dian)(dian)流減小，因而(er)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)不(bu)(bu)轉(zhuan)(zhuan)(zhuan)(zhuan)或(huo)者轉(zhuan)(zhuan)(zhuan)(zhuan)動(dong)(dong)(dong)(dong)很慢。 ?在(zai)傳動(dong)(dong)(dong)(dong)機(ji)(ji)械(xie)中，有機(ji)(ji)械(xie)上(shang)的卡(ka)阻現象，嚴重時電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)就不(bu)(bu)轉(zhuan)(zhuan)(zhuan)(zhuan)，且異常(chang)聲響。 電(dian)(dian)(dian)壓(ya)過低使電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)轉(zhuan)(zhuan)(zhuan)(zhuan)矩減小，啟(qi)動(dong)(dong)(dong)(dong)困難(nan)或(huo)不(bu)(bu)能(neng)啟(qi)動(dong)(dong)(dong)(dong)。 電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)定子，轉(zhuan)(zhuan)(zhuan)(zhuan)子鐵心(xin)相摩(mo)擦(ca)，增加了負載，使轉(zhuan)(zhuan)(zhuan)(zhuan)動(dong)(dong)(dong)(dong)困難(nan)。 ?運行人員發(fa)現上(shang)述故障時，對高壓(ya)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)來講，應立即(ji)拉開電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)的斷(duan)(duan)路(lu)器以(yi)及隔(ge)離(li)開關(guan)，檢查(cha)其定子、轉(zhuan)(zhuan)(zhuan)(zhuan)子回路(lu)。

對于(yu)(yu)YE2電(dian)(dian)(dian)機(ji)(ji)(ji)我(wo)們應該了解下列幾個方(fang)面(mian)的問題：（1）基(ji)本(ben)構造(zao)；（2）工作(zuo)原(yuan)理(li)；（3）表(biao)示轉速與轉矩之間(jian)關系的機(ji)(ji)(ji)械特性；（4）起動、調速及(ji)制動的基(ji)本(ben)原(yuan)理(li)和(he)(he)基(ji)本(ben)方(fang)法(fa)；（5）應用場合和(he)(he)如(ru)何正確使用。三相異步(bu)電(dian)(dian)(dian)動機(ji)(ji)(ji)的兩個基(ji)本(ben)組成部(bu)分(fen)(fen)為定子（固(gu)定部(bu)分(fen)(fen)）和(he)(he)轉子（旋轉部(bu)分(fen)(fen)）。此外還有端蓋、風扇等附(fu)屬部(bu)分(fen)(fen)。鼠籠式電(dian)(dian)(dian)動機(ji)(ji)(ji)由于(yu)(yu)構造(zao)簡單，價格(ge)低(di)廉，東營YE2電(dian)(dian)(dian)機(ji)(ji)(ji)，工作(zuo)可靠，使用方(fang)便，成為了生(sheng)產上(shang)應用得廣泛的一種電(dian)(dian)(dian)動機(ji)(ji)(ji)。
