需要說明的是銘牌中的功率指的是軸功率，也就是電機(jī)的有功功率，上圖中左邊藍(lán)色的為電機(jī)，右邊黑色的為水泵。我們通過銘牌知道了電機(jī)的功率為132KW，用它來拉動(dòng)水泵轉(zhuǎn)動(dòng)的話，水泵的功率必須小于或等于132KW，否則無法正常工作，銘牌上寫有電壓為380V，接法畫了個(gè)三個(gè)角，我們由此可知道他用的是三相交流電，必須使用三角形接法。有些電機(jī)接法上除了畫個(gè)三角形還多一個(gè)/Y，Y**星形接法，這就告訴我們可以用三角形接法或星形接法，如果只是畫了一個(gè)就只能用畫的那個(gè)接法來接，不按它的接法來接有什么后果不用說你也知道。標(biāo)注的電流為239.7A，選用電線的時(shí)候我們就可以通過這個(gè)來決定用多少平方的電線。選用的電線的載電流量必須大于239.7A。

三相電動(dòng)機(jī)在起動(dòng)時(shí)，起動(dòng)電流很大，可達(dá)到額定電流的4~7倍，很大的起動(dòng)電流，在短時(shí)間內(nèi)會(huì)在線路上造成 </p> <p> 較大的電壓降落，這不僅影響電動(dòng)機(jī)本身的起動(dòng)也會(huì)影響到同**路上的其他電動(dòng)機(jī)和電器設(shè)備的正常工作。 </p> <p> 為此，對(duì)大容量電動(dòng)機(jī)且起停頻繁時(shí)，為了限制起動(dòng)電流，必須采取降壓起動(dòng)。所謂降壓起動(dòng)，就是在電動(dòng)機(jī)起 </p> <p> 動(dòng)時(shí)降低加在電動(dòng)機(jī)定子繞組上的電壓，當(dāng)電動(dòng)機(jī)轉(zhuǎn)起來以后，再將加在定子繞組上的電壓恢復(fù)到正常值。由于 </p> <p> 電流與電壓成正比關(guān)系，所以降低起動(dòng)時(shí)的電壓能減小起動(dòng)電流。但是由于電磁轉(zhuǎn)矩與電動(dòng)機(jī)定子繞組端電壓的 </p> <p> 平方成正比，所以電動(dòng)機(jī)在降壓起動(dòng)時(shí)，起動(dòng)轉(zhuǎn)矩相應(yīng)減小，故降壓起動(dòng)適用于空載或輕載下的起動(dòng) </p><p> 監(jiān)視電動(dòng)機(jī)的溫度。運(yùn)行中的電動(dòng)機(jī)都要發(fā)熱，其溫升不應(yīng)超過銘牌上的允許限度。電動(dòng)機(jī)的絕大部分故障都會(huì)使它的定子電流增大，溫度升高，因此，如果發(fā)現(xiàn)電動(dòng)機(jī)的溫度超過允許值，應(yīng)立即停機(jī)檢查，查明嚴(yán)重發(fā)熱的原因，排除故障后才可以運(yùn)行。檢查電動(dòng)機(jī)的溫升常用如下方法：1)手摸。對(duì)中、小容量的電動(dòng)機(jī)，用手背觸摸電動(dòng)機(jī)的外殼，如果沒有發(fā)燙到要縮手的感覺，說明電動(dòng)機(jī)沒有過熱。如果燙得馬上縮手，難以忍受，則說明電動(dòng)機(jī)的溫度已超過了允許值。用手背而不是用手心摸電動(dòng)機(jī)的外殼，是為了防止機(jī)殼一旦帶電時(shí)，手背比手心容易自然地?cái)[脫帶電的外殼。為了防止觸電，比較好在摸機(jī)殼前，先用驗(yàn)電筆檢測(cè)一下機(jī)殼是否帶電。2)滴水。在機(jī)殼上滴幾滴水，如果看見冒熱氣而無聲音，說明電動(dòng)機(jī)沒有過熱；如果既冒熱氣，又聽到“咝咝”聲，說明電動(dòng)機(jī)已過熱，溫升已超過允許值。我公司生產(chǎn)的產(chǎn)品、設(shè)備用途非常多。</p><div

style="text-indent:25px">異步電動(dòng)機(jī)的氣隙是很小的，中小型電動(dòng)機(jī)一般為0.2～2mm。氣隙越大，磁阻越大，要產(chǎn)生同樣大小的磁場(chǎng)，就需要較大的勵(lì)磁電流。由于氣隙的存在，異步電動(dòng)機(jī)的磁路磁阻遠(yuǎn)比變壓器為大，因而異步電動(dòng)機(jī)的勵(lì)磁電流也比變壓器的大得多。變壓器的勵(lì)磁電流約為額定電流的3%，異步電動(dòng)機(jī)的勵(lì)磁電流約為額定電流的30%。勵(lì)磁電流是無功電流，因而勵(lì)磁電流越大。繞組是電動(dòng)機(jī)的組成部分，老化、受潮、受熱、受侵蝕、異物侵入、外力的沖擊都會(huì)造成對(duì)繞組的傷害，電機(jī)過載、欠電壓、過電壓，缺相運(yùn)行也能引起繞組故障。繞組故障一般分為繞組接地、短路、開路、接線錯(cuò)誤。如今分別說明故障現(xiàn)象、產(chǎn)生的原因及檢查方法。誠(chéng)摯的歡迎業(yè)界新朋老友走進(jìn)聯(lián)創(chuàng)電機(jī)！德州大型電機(jī)</p><p
