電動機，也叫馬達，是一種通過電磁作用實現(xiàn)電能轉(zhuǎn)換成機械能的裝置，因為電有幾種形式，機械結(jié)構(gòu)也不一樣，大型高壓電機生產(chǎn)廠家，磁場形式也會有不同，電機本身的用途場所也會有差異，所以電機會有很多種類型，按照不同的標準，也會有不一樣的叫法和品類了. </p> <p> 一、通過電能的形式來分 </p> <p> 1、電有交流和直流兩種形式，所以電機可以總體分成交流電機和直流電機兩大類。 </p> <p> 2、交流電有單相和三相兩種，大型高壓電機生產(chǎn)廠家，有單相交流電機和三相交流電電機 </p> <p> 3、電壓有高低壓等級之分，所以也有高壓電機和電壓電機的說法。 </p> <p> 二、按照原理來分類 </p> <p> 1、根據(jù)轉(zhuǎn)差率不同，可以分成同步電機和異步電機 </p> <p> 2，大型高壓電機生產(chǎn)廠家、同步電機根據(jù)磁場不一樣，有永磁同步電機，磁滯同步電機和磁阻同步電機。 </p> <p> 3、異步電機，有感應(yīng)形式的，也有交流換向器形式的。而感應(yīng)形式的有三相異步電機和罩極異步電機。交流換向器電機，還分為推斥電機，串激電機。我公司生產(chǎn)的產(chǎn)品、設(shè)備用途非常多。大型高壓電機生產(chǎn)廠家</p><div style="width:100%;text-align: center;"><img style="max-width:

日常工作中最常見的三相異步電動機有鼠籠型電機和繞線式電機。這是根據(jù)它們的轉(zhuǎn)子結(jié)構(gòu)來分類的。從外觀上看，明顯的區(qū)別就是繞線式電機帶轉(zhuǎn)子滑環(huán)，鼠籠式電機不帶。鼠籠型電機轉(zhuǎn)子繞組是自己短路的繞組，在轉(zhuǎn)子在每個槽中放有一根導(dǎo)體，導(dǎo)體比鐵芯長，在鐵芯兩端用兩個端<span style="display:none;"></span>環(huán)將導(dǎo)體短接，形成短路繞組。若將鐵芯去掉，剩下的繞組形狀似松鼠籠子，故稱鼠籠式繞組。 </p> <p> <span style="display:none;"></span>繞線型電機：轉(zhuǎn)子是銅線繞制的線圈，線圈末端是通過滑環(huán)引到啟動控制設(shè)備上。 </p> <p> 繞線式電機 </p> <p> 優(yōu)缺點如下： </p> <p> 1.鼠籠式異步電動機： </p> <p> 優(yōu)點：結(jié)構(gòu)簡單，啟動方便，運行可靠，體積小，堅固耐用，便于維護、檢修和安裝，成本低等。 </p> <p> 缺點：啟動轉(zhuǎn)矩較小，功率因數(shù)較低，轉(zhuǎn)速不易調(diào)節(jié)，直接啟動時啟動電流大。正常情況下，鼠籠型電機冷狀態(tài) </p> <p> 下運行啟動2-3次，每次間隔時間不得小于5分鐘。熱狀態(tài)下運行啟動一次。鼠籠式異步電動機在頻繁啟動時，還 </p> <p> 容易造成鼠籠斷條。 </p> <p> 2.繞線式異步電動機： </p> <p> 優(yōu)點：通過在轉(zhuǎn)子回路中串入外加電阻，降低了啟動電流和轉(zhuǎn)速，增加了啟動轉(zhuǎn)矩?？梢愿纳齐妱訖C的啟動和調(diào) </p> <p> 速性能。 </p> <p>

三相異步電動機的缺相運行是指三相供電電源缺少一相或三相繞組有一相從電源斷開而造成的一種電動機運行狀態(tài)，三相異步電動機的繞組燒毀大多數(shù)是由于缺相運行造成的。下面，我介紹一個簡便方法針對缺相故障進行保護。一、對于星形接法電動機，由于三相交流電的失量和為零，其中性點對地電壓理論上為零，但實際上三相電壓不會平衡，總要相差幾伏電壓。當電機缺相運行時，由于定子三相電壓不平衡，中性點對地的零序電壓升高，當電機滿負荷運行時，此零序電壓可達達25～45伏。此時，可通過串接于電機中性線上的零序電壓繼電器來對電機進行保護，如圖1所示。電機正常運行時，中性點對地電壓較低，Kv不動作。，中性蘭對地電壓升高，使Kv動作，它的常閉觸點斷開而切斷KM線圈電源，隨即主電路斷電。二、對于定子繞組三角形接法的電機，可將星形接法的三只電容器(容量2～4uF為好)接于三角形繞組上，引出人為中性點，如圖2所示。由于實際電路中，中性點對地總有幾伏電壓，因此可以把電壓繼電器整定到12～24伏。此外也可使用市場上的小型中間繼電器(12或24伏)來代替電壓繼電器。這樣更方便些。 </p><p> 電機是生產(chǎn)、制造中比不可少的設(shè)備之一，為了保證電機正常工作，除了按操作規(guī)程正常使用、運行過程中注意正常監(jiān)視和維護外，還應(yīng)該進行定期檢查，做好電機維護保養(yǎng)工作。對于新安裝的電動機定子絕緣電阻應(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，定子絕緣電阻應(yīng)大于0.5MΩ，轉(zhuǎn)子絕緣電阻大于0.5MΩ;如達不到一標準，應(yīng)拆下來干燥；在烘干情況（50~70）定子絕緣電阻達1MΩ，轉(zhuǎn)子絕緣電阻應(yīng)大于0.5MΩ。我們的機械設(shè)備能否正常工作，很重要的一部分就在于電機能否正常運轉(zhuǎn)。所以電機保養(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)，等到電機出現(xiàn)問題了，電機只能維修了，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。聯(lián)創(chuàng)電機愿和各界朋友真誠合作一同開拓。</p><div

高壓電機直接啟動就是在全電壓條件下直接啟動電機。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啟動的時候串入電抗器，以限制和降低電機啟動時的啟動電流及電網(wǎng)壓降，當電機運行穩(wěn)定且電流達到一定值時，切除電抗器變?yōu)殡姍C直接啟動模式。由于啟動過程中電機端的電壓也下降，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啟動時利用自耦變壓器來降低加在電動機定子繞組上的啟動電壓。待電動機啟動后，再使電動機與自耦變壓器脫離，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)電機交通便利，地理位置優(yōu)越。大型高壓電機生產(chǎn)廠家</p><p
