日常工作中，日照大型高壓電機廠商，遇到一臺三相異步電機，往往這樣問，這臺電機是幾極的？比如是2極、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>

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。聯(lián)創(chuàng)電機尊崇團(tuán)結(jié)、信譽、勤奮。日照大型高壓電機廠商</p> <span style="display:none;"></span><div style="width:100%;text-align:
