對于交流電機，額定電壓在1000V及以上的為高壓電機；低于1000V的為低壓電機(有些資料中的界限是1140V)。對于直流電機，額定電壓在1500V及以上的為高壓電機；低于1500V的為低壓電機。那么，高壓電機和低壓電機相比有哪些優(yōu)缺點：額定電壓不一樣，啟動和工作電流不一樣，電壓越高，電流越?。浑姍C的絕緣和耐壓也不一樣，電機繞組的導線也一樣，同樣功率的電機，高電壓的電機導線比低電壓的要少，使用的電纜也不一樣。 </p> <p> 一、線圈的絕緣材料有所區(qū)別，低壓電機，線圈主要采用漆包線或其他簡單的絕緣，如復合紙，高壓電機的絕緣通常采用多層結(jié)構(gòu)，如粉云母帶，結(jié)構(gòu)更復雜，耐壓程度更高。 </p> <p> 二、散熱結(jié)構(gòu)上的區(qū)別，低壓電機主要采用同軸風扇直吹散熱，高壓電機大多數(shù)帶有**的散熱器，通常有兩種風扇，一組內(nèi)循環(huán)風扇，一組外循環(huán)風扇，兩組風扇同時運轉(zhuǎn)，在散熱器上進行熱交換將熱量排出電機外面。 </p> <p> 三，軸承結(jié)構(gòu)不同，廣西三相異步電機廠家排名，低壓電動機通常前后各有一組軸承，而高壓電動機，廣西三相異步電機廠家排名，因為負載較重，通常軸伸端會有兩組軸承，廣西三相異步電機廠家排名，非軸伸端的軸承數(shù)量根據(jù)負載情況而定，而特別大型的電動機會采用滑動軸承。 </p> <p> <br /> </p> <span

高壓電機是指額定電壓在1000V以上電動機。常使用的是6000V和10000V電壓，由于國外的電網(wǎng)不同，也有3300V和6600V的電壓等級。高壓電機產(chǎn)生是由于電機功率與電壓和電流的乘積成正比，因此低壓電機功率增大到一定程度(如300KW/380V)電流受到導線的允許承受能力的限制就難以做大，或成本過高。需要通過提高電壓實現(xiàn)大功率輸出。高壓電機優(yōu)點是功率大，承受沖擊能力強；缺點是慣性大，啟動和制動都困難。高壓電動機可用于驅(qū)動各種不同機械之用。如壓縮機、水泵、破碎機、切削機床、運輸機械及其它設(shè)備，供礦山、機械工業(yè)、石油化工工業(yè)、發(fā)電機等各種工業(yè)中作原動機用。用以傳動鼓風機、磨煤機、軋鋼機、卷揚機的電動機應(yīng)在訂貨時注明用途及技術(shù)要求，采用特殊的設(shè)計以保障可靠運行。高壓電機分為：高壓同步電機；高壓異步電機；高壓異步繞線式電動機；高壓鼠籠型電機等。

銘牌就相當于電機的說明書，上面標注著電機的各種信息，比如功率，電壓，電流，接法等。而我們作為電工或機修，這些都是必不可少的，一臺沒有銘牌的電機就如一只斷了線的風箏，如果電機不見了銘牌，毫不夸張的說等于報廢了，我們平?？匆慌_電機的時候也是首先看銘牌，可知銘牌對電工和機修的重要性。在此也說明一下,上面銘牌的功率是額定功率(有功功率),電壓也為額定電壓(也就是線電壓),電流為額定電流(線電流)，每臺電機上都貼有銘牌的，就算是一臺風扇正規(guī)來說也是貼有的。
