style="text-indent:25px">三相異步電動機由固定的定子和旋轉(zhuǎn)的轉(zhuǎn)子兩個基本部分組成，轉(zhuǎn)子裝在定子內(nèi)腔里，借助軸承被支撐在兩個端蓋上。為了保證轉(zhuǎn)子能在定子內(nèi)自由轉(zhuǎn)動，定子和轉(zhuǎn)子之間必須有一間隙，稱為氣隙。電動機的氣隙是一個非常重要的參數(shù)，其大小及對稱性等對電動機的性能有很大影響。圖2所示定子由定子三相繞組、定子鐵心和機座組成。定子三相繞組是異步電動機的電路部分，在異步電動機的運行中起著很重要的作用，是把電能轉(zhuǎn)換為機械能的關(guān)鍵部件。定子三相繞組的結(jié)構(gòu)是對稱的，一般有六個出線端U1、U2、V1、V2，濰坊大型高壓電機生產(chǎn)廠家、W1、W2，置于機座外側(cè)的接線盒內(nèi)，根據(jù)需要接成星形（Y）或三角形（△），如圖3所示。圖3定子鐵心是異步電動機磁路的一部分，由于主磁場以同步轉(zhuǎn)速相對定子旋轉(zhuǎn)，為減小在鐵心中引起的損耗，鐵心采用0.5mm厚的高導(dǎo)磁硅鋼片疊成，硅鋼片兩面涂有絕緣漆以減小鐵心的渦流損耗。機座又稱機殼，它的主要作用是支撐定子鐵心，同時也承受整個電動機負載運行時產(chǎn)生的反作用力，運行時由于內(nèi)部損耗所產(chǎn)生的熱量也是通過機座向外散發(fā)。中、小型電動機的機座一般采用鑄鐵制成。大型電動機因機身較大澆注不便，常用鋼板焊接成型。為三相籠型異步電動機的組成部件。公司狠抓產(chǎn)品質(zhì)量的提高，濰坊大型高壓電機生產(chǎn)廠家，逐年立項對制造，濰坊大型高壓電機生產(chǎn)廠家、檢測、試驗裝置進行技術(shù)改造。濰坊大型高壓電機生產(chǎn)廠家</p><div

style="text-indent:25px">當(dāng)向三相定子繞組中通入對稱的三相交流電時，就產(chǎn)生了一個以同步轉(zhuǎn)速n1沿定子和轉(zhuǎn)子內(nèi)圓空間作順時針方向旋轉(zhuǎn)的旋轉(zhuǎn)磁場。由于旋轉(zhuǎn)磁場以n1轉(zhuǎn)速旋轉(zhuǎn)，轉(zhuǎn)子導(dǎo)體開始時是靜止的，故轉(zhuǎn)子導(dǎo)體將切割定子旋轉(zhuǎn)磁場而產(chǎn)生感應(yīng)電動勢（感應(yīng)電動勢的方向用右手定則判定）。由于轉(zhuǎn)子導(dǎo)體兩端被短路環(huán)短接，在感應(yīng)電動勢的作用下，轉(zhuǎn)子導(dǎo)體中將產(chǎn)生與感應(yīng)電動勢方向基本一致的感生電流。轉(zhuǎn)子的載流導(dǎo)體在定子磁場中受到電磁力的作用（力的方向用左手定則判定）。電磁力對轉(zhuǎn)子軸產(chǎn)生電磁轉(zhuǎn)矩，驅(qū)動轉(zhuǎn)子沿著旋轉(zhuǎn)磁場方向旋轉(zhuǎn)。通過上述分析可以總結(jié)出電動機工作原理為：當(dāng)電動機的三相定子繞組（各相差120度電角度），通入三相對稱交流電后，將產(chǎn)生一個旋轉(zhuǎn)磁場，該旋轉(zhuǎn)磁場切割轉(zhuǎn)子繞組，從而在轉(zhuǎn)子繞組中產(chǎn)生感應(yīng)電流（轉(zhuǎn)子繞組是閉合通路），載流的轉(zhuǎn)子導(dǎo)體在定子旋轉(zhuǎn)磁場作用下將產(chǎn)生電磁力，從而在電機轉(zhuǎn)軸上形成電磁轉(zhuǎn)矩，驅(qū)動電動機旋轉(zhuǎn)，并且電機旋轉(zhuǎn)方向與旋轉(zhuǎn)磁場方向相同。吉林三相同步電機零配件聯(lián)創(chuàng)電機生產(chǎn)的產(chǎn)品質(zhì)量上乘。</p><div

吊入式機座是一個長方體的箱式結(jié)構(gòu)，機座內(nèi)部軸向有筋，用于支撐和固定定子。定子是從上方放入機座，靠定子壓圈與機座軸向筋定位并保證氣隙均勻度。再用螺栓將定子與機座緊固。機座端端板的內(nèi)止口與端蓋的外止口緊密配合，能充分保證定、轉(zhuǎn)子之間的氣隙均勻度。壓入式機座大多是通過熱套方式將定子套入機座，該方式下機座與定子的同心度容易保證，但相對與吊入式機座便捷性要遜色一些。 </p> <p> ● 定子線圈：定子線圈是雙層疊繞阻，絕緣等級為F級，電壓等級為3KV及以上的電機都有防電暈措施。 </p> <p> ● 轉(zhuǎn)子線圈：繞線電機的轉(zhuǎn)子線圈是雙層波繞組，采用矩形銅排，絕緣等級要求為F級。 </p> <p> ● 定子：定子通常采用磁性槽楔，根據(jù)需要也可用非磁性槽楔。線圈端部之間應(yīng)采用適型材料墊緊，并與端箍、支撐桿扎牢在一起，經(jīng)過真空壓力整浸無溶劑漆后，整個定子成為一個整體，增強了其機械性和防潮能力。<span style="display:none;"></span> </p> <p> ● 轉(zhuǎn)子：鼠籠型電機一般情況下采用鑄鋁轉(zhuǎn)子，這種轉(zhuǎn)子運行可靠，并具有較好的起動性能，它可以滿壓直接起動。根據(jù)需要也可采用銅條轉(zhuǎn)子，銅條轉(zhuǎn)子電機效率相對較高，但成本也要高好多。 </p> <p> ● 軸大多焊有輻板，并經(jīng)過熱處理，具有較好的機械性能。高壓電機軸的熱處理非常關(guān)鍵，稍有不慎，會出現(xiàn)斷軸問題。 </p><p style="text-indent:25px">三相異步電機（Triple-phase asynchronous motor）是感應(yīng)電動機的一種，是靠同時接入380V三相交流電流（相位差120度）供電的一類電動機，由于三相異步電動機的轉(zhuǎn)子與定子旋轉(zhuǎn)磁場以相同的方向、不同的轉(zhuǎn)速成旋轉(zhuǎn)，存在轉(zhuǎn)差率，所以叫三相異步電動機。三相異步電動機轉(zhuǎn)子的轉(zhuǎn)速低于旋轉(zhuǎn)磁場的轉(zhuǎn)速，轉(zhuǎn)子繞組因與磁場間存在著相對運動而產(chǎn)生電動勢和電流，并與磁場相互作用產(chǎn)生電磁轉(zhuǎn)矩，實現(xiàn)能量變換。與單相異步電動機相比，三相異步電動機運行性能好，并可節(jié)省各種材料。按轉(zhuǎn)子結(jié)構(gòu)的不同，三相異步電動機可分為籠式和繞線式兩種?；\式轉(zhuǎn)子的異步電動機結(jié)構(gòu)簡單、運行可靠、重量輕、價格便宜，得到了普遍的應(yīng)用，其主要缺點是調(diào)速困難。繞線式三相異步電動機的轉(zhuǎn)子和定子一樣也設(shè)置了三相繞組并通過滑環(huán)、電刷與外部變阻器連接。調(diào)節(jié)變阻器電阻可以改善電動機的起動性能和調(diào)節(jié)電動機的轉(zhuǎn)速。聯(lián)創(chuàng)電機不懈追求產(chǎn)品質(zhì)量，精益求精不斷升級。</p><div
