日常工作中，遇到一臺(tái)三相異步電機(jī)，往往這樣問，這臺(tái)電機(jī)是幾極的？比如是2極，黑龍江三相異步電機(jī)多少錢、4極、6極、8極……然后可 </p> <p> 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(duì)出現(xiàn)，N極和S極，所以一臺(tái)電機(jī)的極數(shù)<span style="display:none;"></span>**少是2極。級(jí)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(shí)所說的這臺(tái)電機(jī)的轉(zhuǎn)速多少，是指這臺(tái)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> p：電機(jī)極對(duì)數(shù)，2極電機(jī)，對(duì)數(shù)是1；4極電機(jī)，對(duì)數(shù)是2；8極電機(jī)，對(duì)數(shù)是4。比如一臺(tái)2極電機(jī)，轉(zhuǎn)速n=60秒 </p> <p> ×50HZ/極對(duì)數(shù)1=3000轉(zhuǎn)，黑龍江三相異步電機(jī)多少錢。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(chǎng)轉(zhuǎn)速，所以，異步轉(zhuǎn)速還涉 </p> <p> 及到電機(jī)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，黑龍江三相異步電機(jī)多少錢，不同廠家生產(chǎn)的電機(jī)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(jī)異步轉(zhuǎn)速=3000×（1-4%）=2880轉(zhuǎn)左右。 </p> <p> 同樣算法，6極電機(jī)異步轉(zhuǎn)速=（60秒×50赫茲/極對(duì)數(shù)3）×（1-轉(zhuǎn)差率4%）=960轉(zhuǎn)左右。 </p> <span

在電氣工程施工中，如何計(jì)算不同電壓等級(jí)的三相電動(dòng)機(jī)額定電流呢，這里有一個(gè)口訣：容量除以千伏數(shù)，商乘系數(shù)點(diǎn)七六。這個(gè)口訣具體是怎么應(yīng)用的呢?下面為您詳細(xì)闡述。由公式及口訣均可說明容量相同的電壓等級(jí)不同的電動(dòng)機(jī)的額定電流是不相同的，即電壓千伏數(shù)不一樣，去除以相同的容量，所得“商數(shù)”顯然不相同，不相同的商數(shù)去乘相同的系數(shù)0.76，所得的電流值也不相同。若把以上口訣叫做通用口訣，則可推導(dǎo)出計(jì)算220、380、660、3.6kV電壓等級(jí)電動(dòng)機(jī)的額定電流**計(jì)算口訣，用**計(jì)算口訣計(jì)算某臺(tái)三相電動(dòng)機(jī)額定電流時(shí)，容量千瓦與電流安培關(guān)系直接倍數(shù)化，省去了容量除以千伏數(shù)，商數(shù)再乘系數(shù)0.76。三相二百二電機(jī)，千瓦三點(diǎn)五安培。常用三百八電機(jī)，一個(gè)千瓦兩安培。低壓六百六電機(jī)，千瓦一點(diǎn)二安培。高壓三千伏電機(jī)，四個(gè)千瓦一安培。高壓六千伏電機(jī)，八個(gè)千瓦一安培。

電動(dòng)機(jī)故障的原因有：電源斷相、電壓或頻率不對(duì)；繞組短路、斷路、接地；軸承運(yùn)轉(zhuǎn)不良；內(nèi)、外部臟，散熱不好（外部涂油漆太厚也是散熱不好的原因），和自帶冷卻風(fēng)扇壞，通風(fēng)不暢；與機(jī)械裝備不良；長期高負(fù)荷運(yùn)行；環(huán)境溫度高等等。90%以上都是日常管理檢查不細(xì)，電機(jī)維護(hù)保養(yǎng)不足造成的。電動(dòng)機(jī)是日常生產(chǎn)中比不可少的設(shè)備之一，因此，它的日常維護(hù)就顯得相當(dāng)?shù)闹匾?。電?dòng)機(jī)由定子架、繞組及絕緣材料、轉(zhuǎn)子、兩端軸承及端蓋等組成，比較簡單。電動(dòng)機(jī)故障的原因有：電源斷相、電壓或頻率不對(duì)；繞組短路、斷路、接地；軸承運(yùn)轉(zhuǎn)不良；內(nèi)、外部臟，散熱不好（外部涂油漆太厚也是散熱不好的原因），和自帶冷卻風(fēng)扇壞，通風(fēng)不暢；與機(jī)械裝備不良；長期高負(fù)荷運(yùn)行；環(huán)境溫度高等等。電動(dòng)機(jī)的損壞，90%以上都是維修人員日常檢查不細(xì)，維護(hù)保養(yǎng)不足造成的，只要堅(jiān)持認(rèn)真看、聽、摸、測(cè)、做，絕大多數(shù)故障都可以預(yù)防和避免，減少公司備件和修理費(fèi)用的損失。
