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，用它來拉動水泵轉(zhuǎn)動的話，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，接法畫了個三個角，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)接法上除了畫個三角形還多一個/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，如果只是畫了一個就只能用畫的那個接法來接，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，選用電線的時候我們就可以通過這個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。

電機(jī)是生產(chǎn)、制造中比不可少的設(shè)備之一，為了保證電機(jī)正常工作，除了按操作規(guī)程正常使用、運行過程中注意正常監(jiān)視和維護(hù)外，還應(yīng)該進(jìn)行定期檢查，做好電機(jī)維護(hù)保養(yǎng)工作。對于新安裝的電動機(jī)定子絕緣電阻應(yīng)大于2MΩ，轉(zhuǎn)子絕緣電阻應(yīng)大于0.8MΩ；對使用中的電動機(jī)，定子絕緣電阻應(yīng)大于0.5MΩ，轉(zhuǎn)子絕緣電阻大于0.5MΩ;如達(dá)不到一標(biāo)準(zhǔn)，應(yīng)拆下來干燥；在烘干情況（50~70）定子絕緣電阻達(dá)1MΩ，轉(zhuǎn)子絕緣電阻應(yīng)大于0.5MΩ。我們的機(jī)械設(shè)備能否正常工作，很重要的一部分就在于電機(jī)能否正常運轉(zhuǎn)。所以電機(jī)保養(yǎng)也是很重要的，很多人總是不注意保養(yǎng)或者不知道怎么保養(yǎng)，等到電機(jī)出現(xiàn)問題了，電機(jī)只能維修了，維修的話既要花錢，還耽誤工作。才后悔之前沒有做好保養(yǎng)。保養(yǎng)也是一門大學(xué)問。 </p><p> 高壓電機(jī)直接啟動就是在全電壓條件下直接啟動電機(jī)。如果電網(wǎng)條件允許，可以采用直接啟動。但在實際生產(chǎn)過程中往往由于電網(wǎng)容量有限，很少采用直接啟動。由于采用直接啟動時，啟動電流大，使電壓下降幅度較大，對于供電系統(tǒng)有較大的沖擊，如果壓降超過一定值，有可能導(dǎo)致上級變電所跳閘。故在實際運行中很少采用這種直接啟動方法。串聯(lián)電抗器啟動就是在電機(jī)啟動的時候串入電抗器，以限制和降低電機(jī)啟動時的啟動電流及電網(wǎng)壓降，當(dāng)電機(jī)運行穩(wěn)定且電流達(dá)到一定值時，切除電抗器變?yōu)殡姍C(jī)直接啟動模式。由于啟動過程中電機(jī)端的電壓也下降，容易導(dǎo)致啟動轉(zhuǎn)矩不夠，在啟動過程中還會出現(xiàn)一個二次沖擊的過程。自耦變壓器啟動是指電動機(jī)啟動時利用自耦變壓器來降低加在電動機(jī)定子繞組上的啟動電壓。待電動機(jī)啟動后，再使電動機(jī)與自耦變壓器脫離，從而在全壓下正常運行。優(yōu)點是可以按容許的啟動電流和所需的啟動轉(zhuǎn)矩來選擇自耦變壓器副邊的不同抽頭實現(xiàn)降壓啟動，而且不論電動機(jī)定子繞組采用星形接法或三角形接法都可以使用。缺點是設(shè)備的體積較大，因而成本較貴。聯(lián)創(chuàng)電機(jī)設(shè)備的引進(jìn)更加豐富了公司的設(shè)備品種，為用戶提供了更多的選擇空間。</p><div

style="text-indent:25px">現(xiàn)代電機(jī)通常都是高速運轉(zhuǎn)的，它的運轉(zhuǎn)速度每分鐘能夠達(dá)到數(shù)百甚至數(shù)千轉(zhuǎn)，這樣高的運轉(zhuǎn)速度要進(jìn)行高低速的變換是相對困難的，但是很多應(yīng)用場合恰恰就有這樣的需求。因此，就需要現(xiàn)代電機(jī)為其提供轉(zhuǎn)換轉(zhuǎn)速的配件系統(tǒng)。但是這樣的轉(zhuǎn)換系統(tǒng)必然會增加整個電機(jī)系統(tǒng)的大小，并且也會影響到設(shè)備的精確度和工作效率。這時候，只有使現(xiàn)代電機(jī)驅(qū)動向直接驅(qū)動發(fā)展，才能有效的解決這一問題?，F(xiàn)代工業(yè)的發(fā)展經(jīng)常需要電機(jī)的極速化，即經(jīng)常需要電機(jī)保持極高或者極低的速度。現(xiàn)代電機(jī)要極速化的要求與電機(jī)的直驅(qū)化緊密相關(guān)。電機(jī)的極速化，不僅有助于實現(xiàn)電機(jī)的直驅(qū)化，而且可以提高電機(jī)的工作效率和設(shè)備的精確度。聯(lián)創(chuàng)電機(jī)愿與各界朋友攜手共進(jìn)，共創(chuàng)未來！新疆中型電機(jī)價格</p><p

較大的電壓降落，這不僅影響電動機(jī)本身的起動也會影響到同**路上的其他電動機(jī)和電器設(shè)備的正常工作。 </p> <p> 為此，對大容量電動機(jī)且起停頻繁時，為了限制起動電流，必須采取降壓起動。所謂降壓起動，就是在電動機(jī)起 </p> <p> 動時降低加在電動機(jī)定子繞組上的電壓，當(dāng)電動機(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，所以降低起動時的電壓能減小起動電流。但是由于電磁轉(zhuǎn)矩與電動機(jī)定子繞組端電壓的 </p> <p> 平方成正比，所以電動機(jī)在降壓起動時，起動轉(zhuǎn)矩相應(yīng)減小，故降壓起動適用于空載或輕載下的起動河北電機(jī)報價</p><p
