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，山東三相同步電機價格，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。籠式轉(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，山東三相同步電機價格，其主要缺點是調(diào)速困難，山東三相同步電機價格。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)電機愿和各界朋友真誠合作一同開拓。山東三相同步電機價格</p><div

style="text-indent:25px">現(xiàn)代電機通常都是高速運轉(zhuǎn)的，它的運轉(zhuǎn)速度每分鐘能夠達(dá)到數(shù)百甚至數(shù)千轉(zhuǎn)，這樣高的運轉(zhuǎn)速度要進行高低速的變換是相對困難的，但是很多應(yīng)用場合恰恰就有這樣的需求。因此，就需要現(xiàn)代電機為其提供轉(zhuǎn)換轉(zhuǎn)速的配件系統(tǒng)。但是這樣的轉(zhuǎn)換系統(tǒng)必然會增加整個電機系統(tǒng)的大小，并且也會影響到設(shè)備的精確度和工作效率。這時候，只有使現(xiàn)代電機驅(qū)動向直接驅(qū)動發(fā)展，才能有效的解決這一問題。現(xiàn)代工業(yè)的發(fā)展經(jīng)常需要電機的極速化，即經(jīng)常需要電機保持極高或者極低的速度?，F(xiàn)代電機要極速化的要求與電機的直驅(qū)化緊密相關(guān)。電機的極速化，不僅有助于實現(xiàn)電機的直驅(qū)化，而且可以提高電機的工作效率和設(shè)備的精確度。山東大型電機廠家排名聯(lián)創(chuàng)電機產(chǎn)品**國內(nèi)。</p><div

style="text-indent:25px">高壓電機可以做得功率很大，比較大可達(dá)到幾千甚至幾萬千瓦。這是因為，在同樣的輸出功率時，高壓電機的電流可比低壓電機小很多（基本上是與電壓成反比關(guān)系），例如500kW、4極電機的額定電流，額定電壓為380V時為900A左右，而額定電壓為10kV時只有30A左右。所以高壓電機繞組可用較小的線徑。由此，高壓電機的定子銅損耗也會比低壓電機少。對于較大功率的電機，使用低壓電時，則因需要較粗的導(dǎo)線而需要很大面積的定子槽，使定子鐵芯直徑做得很大，電機整個體積也會很大。對于較大容量的電機，高壓電機所用電源和配電設(shè)備比低壓電機的總體投資少，并且線路損耗小，可節(jié)省一定的耗電量。特別是10kV的高壓電機，可直接使用網(wǎng)絡(luò)電源（我國提供給用戶的高壓電一般都是10kV），這樣在電源設(shè)備（主要是變壓器）上的投資會更少，使用也較簡便，故障率也會較少。</p><p> 高壓電機直接啟動就是在全電壓條件下直接啟動電機。如果電網(wǎng)條件允許，可以采用直接啟動。但在實際生產(chǎn)過程中往往由于電網(wǎng)容量有限，很少采用直接啟動。由于采用直接啟動時，啟動電流大，使電壓下降幅度較大，對于供電系統(tǒng)有較大的沖擊，如果壓降超過一定值，有可能導(dǎo)致上級變電所跳閘。故在實際運行中很少采用這種直接啟動方法。串聯(lián)電抗器啟動就是在電機啟動的時候串入電抗器，以限制和降低電機啟動時的啟動電流及電網(wǎng)壓降，當(dāng)電機運行穩(wěn)定且電流達(dá)到一定值時，切除電抗器變?yōu)殡姍C直接啟動模式。由于啟動過程中電機端的電壓也下降，容易導(dǎo)致啟動轉(zhuǎn)矩不夠，在啟動過程中還會出現(xiàn)一個二次沖擊的過程。自耦變壓器啟動是指電動機啟動時利用自耦變壓器來降低加在電動機定子繞組上的啟動電壓。待電動機啟動后，再使電動機與自耦變壓器脫離，從而在全壓下正常運行。優(yōu)點是可以按容許的啟動電流和所需的啟動轉(zhuǎn)矩來選擇自耦變壓器副邊的不同抽頭實現(xiàn)降壓啟動，而且不論電動機定子繞組采用星形接法或三角形接法都可以使用。缺點是設(shè)備的體積較大，因而成本較貴。聯(lián)創(chuàng)電機具備雄厚的實力和豐富的實踐經(jīng)驗。</p><div
