有些電動機繞組的引線只有三根，不能檢測繞組間絕緣，重繞電動機的絕緣電阻一般不應(yīng)低于5兆歐。在線: 在電動機運行時，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，青海高壓電機，則可能有匝間短路，青海高壓電機。有時需要脫開負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。另外電動機的Y、△形接法不能搞錯，青海高壓電機，若錯將Y形接成△形，工作電流會增大；反之，則減小。同時，如電動機的繞組接線錯誤，或繞組匝數(shù)減少，舊電動機的定轉(zhuǎn)子間氣隙過大(正常0.2-1.0mm)都會使空載電流加大，這些要點可以幫助我們判斷日常運行電動機狀況的好壞。 </p> <p> <br /> </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。 </p> <span
