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、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

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(guó)為50HZ。 </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，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。棗莊三相異步電機(jī)價(jià)格聯(lián)創(chuàng)電機(jī)產(chǎn)品**國(guó)內(nèi)。</p> <span style="display:none;"></span><div
