起(qi)重電(dian)機
起(qi)重(zhong)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)及(ji)冶金(jin)用變(bian)頻調(diao)速電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)(ji)為鼠籠轉子電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)(ji)。它集(ji)傳統的(de)起(qi)重(zhong)冶金(jin)用電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)(ji)優點及(ji)變(bian)頻電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)優點于一身，使電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)(ji)不(bu)僅可(ke)以(yi)滿(man)足(zu)頻起(qi)動(dong)(dong)、制動(dong)(dong)、過載、逆轉、超(chao)速、沖擊和振動(dong)(dong)工作(zuo)場合(he)的(de)需要，還(huan)可(ke)滿(man)足(zu)變(bian)頻器(qi)控制下運(yun)行(xing)的(de)需要，實現軟啟動(dong)(dong)、四象限運(yun)行(xing)等(deng)(deng)，從而減(jian)少對(dui)設(she)備的(de)沖擊，并(bing)節約能源(yuan)。電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)(ji)額(e)定電(dian)(dian)(dian)壓380V，額(e)定頻率50Hz，基準工作(zuo)制S3-40%。電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)采用強迫通風冷卻(que)方(fang)式，使得電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)在寬(kuan)廣的(de)頻率范圍內均有良(liang)好的(de)散(san)熱(re)效果。電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)絕緣(yuan)等(deng)(deng)級及(ji)防護等(deng)(deng)級的(de)設(she)置與YZ、YZR電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)相同。電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)安裝(zhuang)尺寸與YZ、YZR電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)相同，從而保(bao)證了良(liang)好的(de)互換性。電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)(ji)外形采用新(xin)的(de)設(she)計，美(mei)觀大方(fang)。H160以(yi)上電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)帶獨立供電(dian)(dian)(dian)的(de)冷卻(que)風機(ji)(ji)(ji)(ji)(ji)，以(yi)滿(man)足(zu)低頻段(duan)運(yun)行(xing)時通風散(san)熱(re)的(de)要求(qiu)。基本系列不(bu)帶編(bian)碼器(qi)、超(chao)速開(kai)關等(deng)(deng)（適合(he)于開(kai)關控制），編(bian)碼器(qi)、超(chao)速開(kai)關、制動(dong)(dong)器(qi)等(deng)(deng)可(ke)按用戶需求(qiu)加(jia)裝(zhuang)。是(shi)冶金(jin)、起(qi)重(zhong)機(ji)(ji)(ji)(ji)(ji)械的(de)理(li)想動(dong)(dong)力，產品廣泛用于冶金(jin)、起(qi)重(zhong)、水利電(dian)(dian)(dian)力等(deng)(deng)行(xing)業。
