以通過它的極數(shù)判斷它的額定轉(zhuǎn)速。那么電機(jī)的極數(shù)和轉(zhuǎn)速有什么關(guān)系呢？電機(jī)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(jī)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(jì)算。n：轉(zhuǎn)速。 </p> <p> 60：60秒，我們平時所說的這臺電機(jī)的轉(zhuǎn)速多少，是指這臺電機(jī)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>

×50HZ/極對數(shù)1=3000轉(zhuǎn)。但這是同步轉(zhuǎn)速，異步電機(jī)，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>

異步轉(zhuǎn)速和轉(zhuǎn)差率關(guān)系：N=(60F/P)×(1-S%)，所以2極電機(jī)異步轉(zhuǎn)速=3000×（1-4%）=2880轉(zhuǎn)左右，菏澤三相同步電機(jī)零配件。 </p> <p> 同樣算法，6極電機(jī)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，菏澤三相同步電機(jī)零配件。公司地理位置優(yōu)越，擁有完善的服務(wù)體系。菏澤三相同步電機(jī)零配件</p> <span style="display:none;"></span><div

在電動機(jī)停止運(yùn)行時，要定期（每月）用絕緣表測量其各相對地或相間絕緣電阻，并與上月測試結(jié)果相比較，以便及時發(fā)現(xiàn)絕緣缺點(diǎn)，發(fā)現(xiàn)不良時用烘潮燈烘烤以提高絕緣，避免因絕緣太低（推薦值>1兆歐）擊穿繞組燒壞電動機(jī)。沒有烘潮電加熱的電動機(jī)除非特殊情況，不要隨意關(guān)掉加熱開關(guān)。在潮濕天氣和冬季時要特別注意電動機(jī)的防水、防潮和烘干。對露天及潮濕場所的電動機(jī)要特別注意水密，對懷疑嚴(yán)重受潮或?yàn)R過水的電動機(jī)，使用前更應(yīng)認(rèn)真檢查。如果發(fā)現(xiàn)電動機(jī)浸泡水，只要將電動機(jī)解體后抽出轉(zhuǎn)子，并用壓縮空氣吹干后，再用烤燈從電動機(jī)定子內(nèi)兩端烘烤，直止電動機(jī)絕緣升至正常。 </p><p> 有些電動機(jī)繞組的引線只有三根，不能檢測繞組間絕緣，重繞電動機(jī)的絕緣電阻一般不應(yīng)低于5兆歐。在線: 在電動機(jī)運(yùn)行時，可測量其三相工作電壓和電流，看是否均衡。電壓應(yīng)基本相等，各相電流與平均值的誤差不應(yīng)超過10%，如用鉗形表測得的各相電流差值太大，則可能有匝間短路。有時需要脫開負(fù)載測量空載電流大小，一般2極約2800rpm，1/3 Ie（額定電流）；4極約1600rpm，40%左右 Ie；6極約900rpm，55% Ie。它會因極數(shù)與容量的不同而不同。另外電動機(jī)的Y、△形接法不能搞錯，若錯將Y形接成△形，工作電流會增大；反之，則減小。同時，如電動機(jī)的繞組接線錯誤，或繞組匝數(shù)減少，舊電動機(jī)的定轉(zhuǎn)子間氣隙過大(正常0.2-1.0mm)都會使空載電流加大，這些要點(diǎn)可以幫助我們判斷日常運(yùn)行電動機(jī)狀況的好壞。 </p> <p>
