對(duì)于交流電機(jī)，額定電壓在1000V及以上的為高壓電機(jī)；低于1000V的為低壓電機(jī)(有些資料中的界限是1140V)。對(duì)于直流電機(jī)，額定電壓在1500V及以上的為高壓電機(jī)；低于1500V的為低壓電機(jī)。那么，高壓電機(jī)和低壓電機(jī)相比有哪些優(yōu)缺點(diǎn)：額定電壓不一樣，啟動(dòng)和工作電流不一樣，電壓越高，電流越??；電機(jī)的絕緣和耐壓也不一樣，云南中型高壓電機(jī)報(bào)價(jià)，電機(jī)繞組的導(dǎo)線也一樣，同樣功率的電機(jī)，高電壓的電機(jī)導(dǎo)線比低電壓的要少，使用的電纜也不一樣。 </p> <p> 一、線圈的絕緣材料有所區(qū)別，低壓電機(jī)，線圈主要采用漆包線或其他簡(jiǎn)單的絕緣，如復(fù)合紙，高壓電機(jī)的絕緣通常采用多層結(jié)構(gòu)，如粉云母帶，結(jié)構(gòu)更復(fù)雜，耐壓程度更高。 </p> <p> 二、散熱結(jié)構(gòu)上的區(qū)別，低壓電機(jī)主要采用同軸風(fēng)扇直吹散熱，高壓電機(jī)大多數(shù)帶有**的散熱器，通常有兩種風(fēng)扇，一組內(nèi)循環(huán)風(fēng)扇，一組外循環(huán)風(fēng)扇，兩組風(fēng)扇同時(shí)運(yùn)轉(zhuǎn)，在散熱器上進(jìn)行熱交換將熱量排出電機(jī)外面。 </p> <p> 三，軸承結(jié)構(gòu)不同，低壓電動(dòng)機(jī)通常前后各有一組軸承，而高壓電動(dòng)機(jī)，因?yàn)樨?fù)載較重，通常軸伸端會(huì)有兩組軸承，云南中型高壓電機(jī)報(bào)價(jià)，非軸伸端的軸承數(shù)量根據(jù)負(fù)載情況而定，而特別大型的電動(dòng)機(jī)會(huì)采用滑動(dòng)軸承，云南中型高壓電機(jī)報(bào)價(jià)。 </p> <p> <br /> 公司實(shí)力雄厚，產(chǎn)品質(zhì)量可靠。云南中型高壓電機(jī)報(bào)價(jià)</p> <span style="display:none;"></span><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

有些電動(dòng)機(jī)繞組的引線只有三根，不能檢測(cè)繞組間絕緣，重繞電動(dòng)機(jī)的絕緣電阻一般不應(yīng)低于5兆歐。在線: 在電動(dòng)機(jī)運(yùn)行時(shí)，可測(cè)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(guò)10%，如用鉗形表測(cè)得的各相電流差值太大，則可能有匝間短路。有時(shí)需要脫開(kāi)負(fù)載測(cè)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(huì)因極數(shù)與容量的不同而不同。另外電動(dòng)機(jī)的Y、△形接法不能搞錯(cuò)，若錯(cuò)將Y形接成△形，工作電流會(huì)增大；反之，則減小。同時(shí)，如電動(dòng)機(jī)的繞組接線錯(cuò)誤，或繞組匝數(shù)減少，舊電動(dòng)機(jī)的定轉(zhuǎn)子間氣隙過(guò)大(正常0.2-1.0mm)都會(huì)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(dòng)機(jī)狀況的好壞。

style="text-indent:25px">現(xiàn)代電機(jī)通常都是高速運(yùn)轉(zhuǎn)的，它的運(yùn)轉(zhuǎn)速度每分鐘能夠達(dá)到數(shù)百甚至數(shù)千轉(zhuǎn)，這樣高的運(yùn)轉(zhuǎn)速度要進(jìn)行高低速的變換是相對(duì)困難的，但是很多應(yīng)用場(chǎng)合恰恰就有這樣的需求。因此，就需要現(xiàn)代電機(jī)為其提供轉(zhuǎn)換轉(zhuǎn)速的配件系統(tǒng)。但是這樣的轉(zhuǎn)換系統(tǒng)必然會(huì)增加整個(gè)電機(jī)系統(tǒng)的大小，并且也會(huì)影響到設(shè)備的精確度和工作效率。這時(shí)候，只有使現(xiàn)代電機(jī)驅(qū)動(dòng)向直接驅(qū)動(dòng)發(fā)展，才能有效的解決這一問(wèn)題?，F(xiàn)代工業(yè)的發(fā)展經(jīng)常需要電機(jī)的極速化，即經(jīng)常需要電機(jī)保持極高或者極低的速度?，F(xiàn)代電機(jī)要極速化的要求與電機(jī)的直驅(qū)化緊密相關(guān)。電機(jī)的極速化，不僅有助于實(shí)現(xiàn)電機(jī)的直驅(qū)化，而且可以提高電機(jī)的工作效率和設(shè)備的精確度。</p><p style="text-indent:25px">同步電動(dòng)機(jī)工作時(shí)，定子的三相繞組中通入三相對(duì)稱電流，轉(zhuǎn)子的勵(lì)磁繞組通入直流電流。在定子三相對(duì)稱繞組中通入三相交變電流時(shí)，將在氣隙中產(chǎn)生旋轉(zhuǎn)磁場(chǎng)。在轉(zhuǎn)子勵(lì)磁繞組中通入直流電流時(shí)，將產(chǎn)生極性恒定的靜止磁場(chǎng)。若轉(zhuǎn)子磁場(chǎng)的磁極對(duì)數(shù)與定子磁場(chǎng)的磁極對(duì)數(shù)相等，轉(zhuǎn)子磁場(chǎng)因受定子磁場(chǎng)磁拉力作用而隨定子旋轉(zhuǎn)磁場(chǎng)同步旋轉(zhuǎn)，即轉(zhuǎn)子以等同于旋轉(zhuǎn)磁場(chǎng)的速度、方向旋轉(zhuǎn)，這就是同步電動(dòng)機(jī)的基本工作原理。同步電機(jī)的主要運(yùn)行方式有三種，即作為發(fā)電機(jī)、電動(dòng)機(jī)和補(bǔ)償機(jī)運(yùn)行。作為發(fā)電機(jī)運(yùn)行是同步電機(jī)主要的運(yùn)行方式。聯(lián)創(chuàng)電機(jī)以質(zhì)量求生存，以信譽(yù)求發(fā)展！</p><div
