振動異步電機設備

異(yi)步(bu)電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)按(an)照轉(zhuan)(zhuan)子結構分為兩種形式:有(you)鼠籠式(異(yi)步(bu)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)鼠籠式異(yi)步(bu)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji))、繞(rao)(rao)線式異(yi)步(bu)電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)。作電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)運(yun)行的(de)(de)(de)異(yi)步(bu)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)。因其(qi)轉(zhuan)(zhuan)子繞(rao)(rao)組電(dian)(dian)(dian)(dian)(dian)流是感應產(chan)生的(de)(de)(de)，又稱感應電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)。異(yi)步(bu)電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)是各(ge)類電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)中(zhong)(zhong)(zhong)應用zui廣(guang)、需要量(liang)zui大的(de)(de)(de)一種。各(ge)國的(de)(de)(de)以電(dian)(dian)(dian)(dian)(dian)為動(dong)(dong)力的(de)(de)(de)機(ji)(ji)(ji)(ji)械中(zhong)(zhong)(zhong)，約(yue)有(you)90%左右為異(yi)步(bu)電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)，其(qi)中(zhong)(zhong)(zhong)小型(xing)異(yi)步(bu)電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)約(yue)占70%以上。在(zai)電(dian)(dian)(dian)(dian)(dian)力系統的(de)(de)(de)總負(fu)(fu)荷中(zhong)(zhong)(zhong)，異(yi)步(bu)電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)的(de)(de)(de)用電(dian)(dian)(dian)(dian)(dian)量(liang)占相當大的(de)(de)(de)比(bi)重(zhong)。在(zai)中(zhong)(zhong)(zhong)國，異(yi)步(bu)電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)的(de)(de)(de)用電(dian)(dian)(dian)(dian)(dian)量(liang)約(yue)占總負(fu)(fu)荷的(de)(de)(de)60%多。

異(yi)步(bu)電(dian)機(ji)是(shi)(shi)一(yi)(yi)(yi)種交流電(dian)機(ji)，其負載時的(de)(de)(de)轉速與所接電(dian)網頻率之比不(bu)是(shi)(shi)恒定值。感應(ying)電(dian)機(ji)（Induction motor）是(shi)(shi)一(yi)(yi)(yi)種僅有一(yi)(yi)(yi)套繞組(zu)聯(lian)接電(dian)源(yuan)的(de)(de)(de)異(yi)步(bu)電(dian)機(ji)。在不(bu)致引起誤解和混(hun)淆的(de)(de)(de)情(qing)況(kuang)下，一(yi)(yi)(yi)般可稱感應(ying)電(dian)動(dong)機(ji)為異(yi)步(bu)電(dian)動(dong)機(ji)。IEC標(biao)準中(zhong)指出：“感應(ying)電(dian)機(ji)"一(yi)(yi)(yi)詞(ci)，在許多國家中(zhong)實(shi)際上是(shi)(shi)作為“異(yi)步(bu)電(dian)機(ji)"的(de)(de)(de)同(tong)義詞(ci)使用，而其他(ta)一(yi)(yi)(yi)些國家則只使用“異(yi)步(bu)電(dian)機(ji)"一(yi)(yi)(yi)詞(ci)來(lai)表示這兩種概念(nian)。
