YE2電(dian)機(ji)串(chuan)(chuan)級調(diao)(diao)速(su)(su)是指(zhi)繞線式(shi)電(dian)動機(ji)轉(zhuan)(zhuan)(zhuan)(zhuan)子回路中串(chuan)(chuan)入可(ke)調(diao)(diao)節的(de)(de)(de)附加(jia)電(dian)勢來(lai)改變(bian)電(dian)動機(ji)的(de)(de)(de)轉(zhuan)(zhuan)(zhuan)(zhuan)差(cha)(cha)，達到(dao)調(diao)(diao)速(su)(su)的(de)(de)(de)目(mu)的(de)(de)(de)。大部分(fen)(fen)轉(zhuan)(zhuan)(zhuan)(zhuan)差(cha)(cha)功(gong)率被串(chuan)(chuan)入的(de)(de)(de)附加(jia)電(dian)勢所吸(xi)收(shou)(shou)，再利用(yong)產(chan)生附加(jia)的(de)(de)(de)裝置，YE2電(dian)機(ji)報價，把吸(xi)收(shou)(shou)的(de)(de)(de)轉(zhuan)(zhuan)(zhuan)(zhuan)差(cha)(cha)功(gong)率返(fan)回電(dian)網或轉(zhuan)(zhuan)(zhuan)(zhuan)換(huan)能量加(jia)以利用(yong)YE2電(dian)機(ji)根據轉(zhuan)(zhuan)(zhuan)(zhuan)差(cha)(cha)功(gong)率吸(xi)收(shou)(shou)利用(yong)方式(shi)，串(chuan)(chuan)級調(diao)(diao)速(su)(su)可(ke)分(fen)(fen)為電(dian)機(ji)串(chuan)(chuan)級調(diao)(diao)速(su)(su)、機(ji)械(xie)串(chuan)(chuan)級調(diao)(diao)速(su)(su)及晶閘管串(chuan)(chuan)級調(diao)(diao)速(su)(su)形式(shi)，多采用(yong)晶閘管串(chuan)(chuan)級調(diao)(diao)速(su)(su).

負(fu)載過(guo)重(zhong)一方面會使(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)起動(dong)(dong)(dong)困難，另外由(you)于過(guo)載運行(xing)將(jiang)使(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)轉速下降，溫升(sheng)過(guo)高(gao).短時(shi)(shi)運行(xing)尚能維(wei)持，YE2電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)加工廠家，若時(shi)(shi)間(jian)過(guo)長，超載的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)將(jiang)從電(dian)(dian)(dian)(dian)(dian)(dian)(dian)網吸收大量的(de)有(you)功功率，因此電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流也迅速增(zeng)大，超過(guo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)允許的(de)額定(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流，損壞絕緣，山東YE2電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)，燒毀電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji).所(suo)以電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)長時(shi)(shi)間(jian)的(de)過(guo)負(fu)荷(he)是不允許的(de)。當電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)負(fu)載過(guo)重(zhong)時(shi)(shi)，YE2電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)定(ding)制廠家，應減輕負(fu)載或更換大容量的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)。
