style="text-indent:25px">直流馬達的應(yīng)用十分的普遍，在生活中更是處處有它的身影，在使用中，我們應(yīng)該按照規(guī)范進行操作，否則就有可能對設(shè)備造成一定的影響，例如馬達表面的損傷，下面我們先來看一下產(chǎn)生表面損傷該怎樣處理。一旦軸承嚴重磨損、負荷過重或受到?jīng)_擊而使直流馬達軸承稍有變形或彎曲，就會造成轉(zhuǎn)子掃膛。掃膛的結(jié)果，輕則使鐵心表面擦傷，重則使鐵心磨損而導(dǎo)致繞組碰殼燒毀，連云港電動電動機修理報價，連云港電動電動機修理報價，應(yīng)立即切斷電源，使減速馬達停止工作，并進行檢查，連云港電動電動機修理報價。溫升試驗馬達的溫升試驗是型式試驗的重要項目，因為絕大多數(shù)馬達的輸出功率都限于溫升，測定溫升一般用電阻法和溫度計法兩種。馬達不轉(zhuǎn)也沒有聲音。原因是馬達電源或繞組有兩相或三相斷路。首先檢查是否有電源電壓。如三相均無電壓，說明故障在電路；若三相電壓平衡，故障在馬達本身。這時可測量馬達三相繞組的電阻，找出斷相的繞組。相當(dāng)于對馬達施加陡度很大的沖擊電壓，使馬達的匝間絕緣承受較為嚴酷的考驗。連云港電動電動機修理報價</p><div

style="text-indent:25px">星形接法由于起輸出功率小，常用于小功率，大扭矩馬達，或功率較大的馬達起步時候用，這樣對機器損耗較小，正常工作后再換用三角形接法。這就是常常說到的星——三角啟動。馬達接法選擇是三相馬達，單相馬達沒有以上兩種接法的說法。一般3KW以下的馬達星型接法的較多，3千瓦以上的馬達一般都角型接法。按規(guī)定，大于15kw的馬達需要星型啟動角型運行，以降低啟動電流。還有小型馬達角型啟動的，如果要接在三相220V電源電壓上，必須接成星型。</p><p style="text-indent:25px">馬達出現(xiàn)問題，馬達維修原因和方法——繞組短路。繞組短路：由于馬達電流過大、電源電壓變動過大、單相運行、機械碰傷、制造不良等造成絕緣損壞所至，分繞組匝間短路、繞組間短路、繞組極間短路和繞組相間短路。1.故障現(xiàn)象。離子的磁場分布不均，三相電流不平衡而使馬達運行時振動和噪聲加劇，嚴重時馬達不能啟動，而在短路線圈中產(chǎn)生很大的短路電流，導(dǎo)致線圈迅速發(fā)熱而燒毀。2.產(chǎn)生原因。馬達長期過載，使絕緣老化失去絕緣作用；嵌線時造成絕緣損壞；繞組受潮使絕緣電阻下降造成絕緣擊穿；端部和層間絕緣材料沒墊好或整形時損壞；端部連接線絕緣損壞；過電壓或遭雷擊使絕緣擊穿；轉(zhuǎn)子與定子繞組端部相互摩擦造成絕緣損壞；金屬異物落入馬達內(nèi)部和油污過多?；赜筒鄣膶挾群蜕疃然蛑睆?、要適中，以便于潤滑油回流順暢。</p><div

style="text-indent:25px">起動馬達的作用是將電能轉(zhuǎn)變成機械能，主要包括了3部分部件：電磁開關(guān)、電子馬達、離合器。馬達是汽車發(fā)動的關(guān)鍵部件，如果它出了問題，那汽車也只能趴窩了；發(fā)馬達起著對蓄電池和用電器供電的作用。下面我們看看起動馬達的和發(fā)馬達常見故障、故障原因及排除方法。當(dāng)我們著車時，通常順時針方向轉(zhuǎn)動點火鑰匙即可發(fā)動起動馬達。每次發(fā)動起動馬達的時間不要超過5秒。如果起動馬達必須發(fā)動一次以上時，先將點火鑰匙退回"I"或"O"的位置。現(xiàn)代轎車用的起動馬達基本上都是終身免維修的。萬一發(fā)現(xiàn)起動系統(tǒng)出現(xiàn)故障，一定要先在車上進行檢查，不要馬上將起動馬達拆卸下來。確認是起動馬達故障而拆卸維修后，在重新安裝之前，務(wù)必先在實驗臺上作好相關(guān)測試。電氣缺陷包括轉(zhuǎn)子籠條與端環(huán)開焊，轉(zhuǎn)子籠條斷裂，繞線錯誤，電刷接觸不良等。連云港電動電動機修理報價</p><p
