style="text-indent:25px">同步電動機工作時，定子的三相繞組中通入三相對稱電流，轉(zhuǎn)子的勵磁繞組通入直流電流。在定子三相對稱繞組中通入三相交變電流時，河南大型電機生產(chǎn)，將在氣隙中產(chǎn)生旋轉(zhuǎn)磁場。在轉(zhuǎn)子勵磁繞組中通入直流電流時，將產(chǎn)生極性恒定的靜止磁場。若轉(zhuǎn)子磁場的磁極對數(shù)與定子磁場的磁極對數(shù)相等，轉(zhuǎn)子磁場因受定子磁場磁拉力作用而隨定子旋轉(zhuǎn)磁場同步旋轉(zhuǎn)，即轉(zhuǎn)子以等同于旋轉(zhuǎn)磁場的速度、方向旋轉(zhuǎn)，這就是同步電動機的基本工作原理，河南大型電機生產(chǎn)。同步電機的主要運行方式有三種，即作為發(fā)電機，河南大型電機生產(chǎn)、電動機和補償機運行。作為發(fā)電機運行是同步電機主要的運行方式。聯(lián)創(chuàng)電機以發(fā)展求壯大，就一定會贏得更好的明天。河南大型電機生產(chǎn)</p><div

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。日照三相異步電機廠商我公司將以優(yōu)良的產(chǎn)品，周到的服務與尊敬的用戶攜手并進！</p> <span style="display:none;"></span><div style="width:100%;text-align:

不但要對檢查中發(fā)現(xiàn)的問題及時采取補救措施，還要按保養(yǎng)周期（每月）對電動機進行螺絲、接線緊固，拆解檢查、清潔保養(yǎng)等。如電動機端蓋4個固定螺絲全部松脫，會造成掃膛運轉(zhuǎn)燒壞；電動機接線螺栓松動虛接造成缺相燒壞；電動機風扇葉脫落抵住機體造成堵轉(zhuǎn)而燒壞；電動機軸承潤滑不良、運行溫度高，而未及時補充潤滑油或更換軸承造成電動機燒壞；電動機因天氣潮濕絕緣電阻下降，不及時烘烤提高絕緣造成擊穿；工段內(nèi)電動機燒壞是因為沒有及時檢查、緊固所致；還是因為雖已發(fā)現(xiàn)問題，但沒做維護保養(yǎng)補救所致。無論是不看不做，還是只看不做，**終都會造成故障或。拆檢電動機時如需更換軸承，要盡可能用進口的，國內(nèi)的會有不少是翻新的舊軸承，質(zhì)量難以保證。如發(fā)現(xiàn)軸承外圓與端蓋軸承座配合不緊密，即軸承走外圓時，要根據(jù)其程度不同，視情采用端蓋軸承座內(nèi)圈打麻點、墊銅皮或鑲銅套消除。一定要定準中心點否則不久又會損壞。投入運行前，要再次確認軸伸出端徑向擺動與端蓋等緊固情況，轉(zhuǎn)子轉(zhuǎn)動是否靈活，繞組引線連接是否正確等等。 </p><p> 監(jiān)視電動機的運行電流。運行中電動機的電流一般不應超過銘牌上規(guī)定的額定電流，已裝電流表的電動機，可以在電動流表上畫一條額定電流的紅線。沒有電流表的小型電動機，也應定期用鉗形電流表測量三相電流。此外，還應注意電動機三相電流是否平衡，任意兩相間的電流差值不應大于額定電流的10%，否則說明電動機有故障。監(jiān)視電源電壓的變化。電源電壓變化范圍不應超過或低于額定電壓的10%，若低于該范圍，應適當減輕負載運行。同時，三相電壓不平衡也不能太大，任意兩相電壓的差值不應超過5%，否則會使電動機發(fā)熱過快。電動機電源比較好裝一只電壓表和一只電壓換相開關(guān)，以便隨時監(jiān)視三相電壓。聯(lián)創(chuàng)電機提供周到的解決方案，滿足客戶不同的服務需要。</p><div

iPad、手機的轉(zhuǎn)變都體現(xiàn)了人們對于電機的小型化和微型化的需求。但是要達到電機從大型化到小型化的轉(zhuǎn)變，首先要提高基礎(chǔ)配件的功率，并且保證基礎(chǔ)元件的性能和改善電機運行的原理。 <p> <br /> </p> <p> <br /> 聯(lián)創(chuàng)電機重信譽、守合同，嚴把產(chǎn)品質(zhì)量關(guān)，熱誠歡迎廣大用戶前來咨詢考察，洽談業(yè)務！日照三相異步電機廠商</p><p style="text-indent:25px">聯(lián)創(chuàng)電機愿和各界朋友真誠合作一同開拓。河南大型電機生產(chǎn)</p><p> 三相異步電機（Triple-phaseasynchronousmotor）是感應電動機的一種，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?；\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。河南大型電機生產(chǎn)</p><p
