異步電機廠家供應簡介：

異步(bu)電(dian)動機按照轉(zhuan)子(zi)結(jie)構分為兩種形式:有鼠籠式(異步(bu)電(dian)機鼠籠式異步電機)、繞線式異(yi)(yi)步(bu)(bu)(bu)電(dian)(dian)(dian)(dian)動(dong)機。作電(dian)(dian)(dian)(dian)動(dong)機運行的(de)(de)(de)(de)異(yi)(yi)步(bu)(bu)(bu)電(dian)(dian)(dian)(dian)機。因其轉子繞組(zu)電(dian)(dian)(dian)(dian)流(liu)是感應產生的(de)(de)(de)(de)，又稱感應電(dian)(dian)(dian)(dian)動(dong)機。異(yi)(yi)步(bu)(bu)(bu)電(dian)(dian)(dian)(dian)動(dong)機是各(ge)類電(dian)(dian)(dian)(dian)動(dong)機中(zhong)應用(yong)zui廣、需要量(liang)zui大的(de)(de)(de)(de)一(yi)種。各(ge)國的(de)(de)(de)(de)以(yi)電(dian)(dian)(dian)(dian)為動(dong)力的(de)(de)(de)(de)機械中(zhong)，約(yue)有90%左右為異(yi)(yi)步(bu)(bu)(bu)電(dian)(dian)(dian)(dian)動(dong)機，其中(zhong)小(xiao)型異(yi)(yi)步(bu)(bu)(bu)電(dian)(dian)(dian)(dian)動(dong)機約(yue)占(zhan)70%以(yi)上(shang)。在電(dian)(dian)(dian)(dian)力系統的(de)(de)(de)(de)總(zong)(zong)負荷(he)中(zhong)，異(yi)(yi)步(bu)(bu)(bu)電(dian)(dian)(dian)(dian)動(dong)機的(de)(de)(de)(de)用(yong)電(dian)(dian)(dian)(dian)量(liang)占(zhan)相當大的(de)(de)(de)(de)比(bi)重。在中(zhong)國，異(yi)(yi)步(bu)(bu)(bu)電(dian)(dian)(dian)(dian)動(dong)機的(de)(de)(de)(de)用(yong)電(dian)(dian)(dian)(dian)量(liang)約(yue)占(zhan)總(zong)(zong)負荷(he)的(de)(de)(de)(de)60%多。

異(yi)步電機是一(yi)種交流電機(ji)，其負載時的(de)轉速(su)與所接電網頻率之比不(bu)是恒定值。感應(ying)電機（Induction motor）是(shi)一(yi)種僅有一(yi)套繞組聯接電(dian)(dian)(dian)源(yuan)的(de)異(yi)步電(dian)(dian)(dian)機(ji)。在不致引起誤解和(he)混淆的(de)情況下，一(yi)般(ban)可稱感(gan)應電(dian)(dian)(dian)動(dong)機(ji)為(wei)異(yi)步電(dian)(dian)(dian)動(dong)機(ji)。IEC標準(zhun)中指出：“感(gan)應電(dian)(dian)(dian)機(ji)”一(yi)詞，在許多國家中實際上是(shi)作為(wei)“異(yi)步電(dian)(dian)(dian)機(ji)”的(de)同義詞使(shi)用，而(er)其他(ta)一(yi)些國家則(ze)只使(shi)用“異(yi)步電(dian)(dian)(dian)機(ji)”一(yi)詞來表(biao)示這(zhe)兩(liang)種概念。

異步電機廠家供應用途：

主要用(yong)作電動機(ji)(ji)(ji)(ji)(ji)(ji)，拖動各種生產(chan)機(ji)(ji)(ji)(ji)(ji)(ji)械，例(li)如：風機(ji)(ji)(ji)(ji)(ji)(ji)、泵、壓縮機(ji)(ji)(ji)(ji)(ji)(ji)、機(ji)(ji)(ji)(ji)(ji)(ji)床、輕工(gong)及礦山(shan)機(ji)(ji)(ji)(ji)(ji)(ji)械、農業生產(chan)中的脫粒機(ji)(ji)(ji)(ji)(ji)(ji)和粉碎機(ji)(ji)(ji)(ji)(ji)(ji)、農副產(chan)品中的加工(gong)機(ji)(ji)(ji)(ji)(ji)(ji)械等(deng)等(deng)。 結構(gou)簡單(dan)、制(zhi)造容易、價格低廉、運行可靠、堅固耐用(yong)、運行效率較高(gao)并(bing)具有適用(yong)的工(gong)作特(te)性

原理：

三相異(yi)步(bu)電(dian)(dian)(dian)(dian)動機(ji)(ji)定(ding)子(zi)(zi)繞(rao)(rao)組加對稱電(dian)(dian)(dian)(dian)壓后，產(chan)生(sheng)一個旋(xuan)轉(zhuan)氣隙(xi)磁(ci)場，轉(zhuan)子(zi)(zi)繞(rao)(rao)組導體(ti)(ti)切割該(gai)磁(ci)場產(chan)生(sheng)感應(ying)(ying)電(dian)(dian)(dian)(dian)勢。由于轉(zhuan)子(zi)(zi)繞(rao)(rao)組處(chu)于短(duan)路狀態會(hui)產(chan)生(sheng)一個轉(zhuan)子(zi)(zi)電(dian)(dian)(dian)(dian)流。轉(zhuan)子(zi)(zi)電(dian)(dian)(dian)(dian)流與氣隙(xi)磁(ci)場相互作用就(jiu)產(chan)生(sheng)電(dian)(dian)(dian)(dian)磁(ci)轉(zhuan)矩(ju)，從(cong)而驅動轉(zhuan)子(zi)(zi)旋(xuan)轉(zhuan)。電(dian)(dian)(dian)(dian)動機(ji)(ji)的轉(zhuan)速一定(ding)低(di)于磁(ci)場同步(bu)轉(zhuan)速，因為只有這樣轉(zhuan)子(zi)(zi)導體(ti)(ti)才可以(yi)感應(ying)(ying)電(dian)(dian)(dian)(dian)勢從(cong)而產(chan)生(sheng)轉(zhuan)子(zi)(zi)電(dian)(dian)(dian)(dian)流和(he)電(dian)(dian)(dian)(dian)磁(ci)轉(zhuan)矩(ju)。所以(yi)該(gai)電(dian)(dian)(dian)(dian)機(ji)(ji)被稱為異(yi)步(bu)機(ji)(ji)，也(ye)叫感應(ying)(ying)電(dian)(dian)(dian)(dian)機(ji)(ji)。
