以通過它的極數(shù)判斷它的額定轉(zhuǎn)速。那么電機的極數(shù)和轉(zhuǎn)速有什么關(guān)系呢？電機的極數(shù)是指每相線圈在定子圓周內(nèi)均勻分布的磁極數(shù)。磁極都是成對出現(xiàn)，N極和S極，所以一臺電機的極數(shù)<span style="display:none;"></span>**少是2極。級數(shù)越多，轉(zhuǎn)速越低，極數(shù)越少，轉(zhuǎn)速越高。轉(zhuǎn)速和極數(shù)的關(guān)系可通過公式：n=60f/p計算。n：轉(zhuǎn)速。 </p> <p> 60：60秒，我們平時所說的這臺電機的轉(zhuǎn)速多少，是指這臺電機每分鐘旋轉(zhuǎn)的周數(shù)，也就是 60秒旋轉(zhuǎn)的周數(shù)。 </p> <p> f:電網(wǎng)頻率，我國為50HZ。 </p> <p> p：電機極對數(shù)，2極電機，對數(shù)是1；4極電機，對數(shù)是2；8極電機，對數(shù)是4。比如一臺2極電機，轉(zhuǎn)速n=60秒 </p> <p> ×50HZ/極對數(shù)1=3000轉(zhuǎn)。但這是同步轉(zhuǎn)速，異步電機，轉(zhuǎn)子轉(zhuǎn)速低于定子旋轉(zhuǎn)磁場轉(zhuǎn)速，所以，異步轉(zhuǎn)速還涉 </p> <p> 及到電機轉(zhuǎn)差率的因素，轉(zhuǎn)差率=（定子轉(zhuǎn)速-轉(zhuǎn)子轉(zhuǎn)速）/定子轉(zhuǎn)速，不同廠家生產(chǎn)的電機轉(zhuǎn)差率也不同，通常在 </p> <p> 10％以內(nèi)，一般在4％左右。 </p> <p> 異步轉(zhuǎn)速和轉(zhuǎn)差率關(guān)系：N=(60F/P)×(1-S%)，所以2極電機異步轉(zhuǎn)速=3000×（1-4%）=2880轉(zhuǎn)左右。 </p> <p> 同樣算法，6極電機異步轉(zhuǎn)速=（60秒×50赫茲/極對數(shù)3）×（1-轉(zhuǎn)差率4%）=960轉(zhuǎn)左右。萊蕪大型高壓電機報價聯(lián)創(chuàng)電機以發(fā)展求壯大，就一定會贏得更好的明天。</p> <span style="display:none;"></span><div style="width:100%;text-align:

style="text-indent:25px">異步電動機的氣隙是很小的，中小型電動機一般為0.2～2mm。氣隙越大，磁阻越大，要產(chǎn)生同樣大小的磁場，就需要較大的勵磁電流。由于氣隙的存在，異步電動機的磁路磁阻遠(yuǎn)比變壓器為大，因而異步電動機的勵磁電流也比變壓器的大得多。變壓器的勵磁電流約為額定電流的3%，異步電動機的勵磁電流約為額定電流的30%。勵磁電流是無功電流，因而勵磁電流越大。繞組是電動機的組成部分，老化、受潮、受熱、受侵蝕、異物侵入、外力的沖擊都會造成對繞組的傷害，電機過載、欠電壓、過電壓，缺相運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、接線錯誤。如今分別說明故障現(xiàn)象、產(chǎn)生的原因及檢查方法。</p><p style="text-indent:25px">三相異步電機（Triple-phase asynchronous motor）是感應(yīng)電動機的一種，是靠同時接入380V三相交流電流（相位差120度）供電的一類電動機，由于三相異步電動機的轉(zhuǎn)子與定子旋轉(zhuǎn)磁場以相同的方向、不同的轉(zhuǎn)速成旋轉(zhuǎn)，存在轉(zhuǎn)差率，所以叫三相異步電動機。三相異步電動機轉(zhuǎn)子的轉(zhuǎn)速低于旋轉(zhuǎn)磁場的轉(zhuǎn)速，轉(zhuǎn)子繞組因與磁場間存在著相對運動而產(chǎn)生電動勢和電流，并與磁場相互作用產(chǎn)生電磁轉(zhuǎn)矩，實現(xiàn)能量變換。與單相異步電動機相比，三相異步電動機運行性能好，并可節(jié)省各種材料。按轉(zhuǎn)子結(jié)構(gòu)的不同，三相異步電動機可分為籠式和繞線式兩種。籠式轉(zhuǎn)子的異步電動機結(jié)構(gòu)簡單、運行可靠、重量輕、價格便宜，得到了普遍的應(yīng)用，其主要缺點是調(diào)速困難。繞線式三相異步電動機的轉(zhuǎn)子和定子一樣也設(shè)置了三相繞組并通過滑環(huán)、電刷與外部變阻器連接。調(diào)節(jié)變阻器電阻可以改善電動機的起動性能和調(diào)節(jié)電動機的轉(zhuǎn)速。聯(lián)創(chuàng)電機嚴(yán)格控制原材料的選取與生產(chǎn)工藝的每個環(huán)節(jié)，保證產(chǎn)品質(zhì)量不出問題。</p><div

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(dǎo)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(fēng)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。濱州中型電機報價</p><p
