提高電動機拖動系統的操作效率，電梯裝飾曳引機(ji)(ji)(ji)變(bian)頻器(qi)是(shi)用(yong)來(lai)取代感應電(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)(ji)速度(du)調節器(qi)作為電(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)(ji)運行(xing)(xing)的(de)目標(biao)，以(yi)(yi)提(ti)高節能(neng)(neng)(neng)措施的(de)效(xiao)率(lv)。傳統(tong)(tong)的(de)蝸輪(lun)(lun)到(dao)行(xing)(xing)星齒輪(lun)(lun)減(jian)速或(huo)無齒輪(lun)(lun)驅(qu)動(dong)(dong)(dong)，機(ji)(ji)(ji)械效(xiao)率(lv)可提(ti)高15％至25％;交流(liu)雙速拖動(dong)(dong)(dong)（AC-2）系統(tong)(tong)，以(yi)(yi)頻率(lv)速率(lv)調節器(qi)驅(qu)動(dong)(dong)(dong)系統(tong)(tong)中(zhong)，可以(yi)(yi)通過在(zai)20％以(yi)(yi)上來(lai)降(jiang)低(di)功耗，電(dian)(dian)梯(ti)(ti)裝(zhuang)(zhuang)(zhuang)(zhuang)(zhuang)飾廠家。常用(yong)的(de)電(dian)(dian)梯(ti)(ti)裝(zhuang)(zhuang)(zhuang)(zhuang)(zhuang)潢(huang)(huang)是(shi)垂直(zhi)運輸設備，提(ti)升機(ji)(ji)(ji)運行(xing)(xing)在(zai)正(zheng)常工(gong)??作拖動(dong)(dong)(dong)或(huo)制動(dong)(dong)(dong)發(fa)電(dian)(dian)狀態(tai)(tai)。當不平(ping)衡負荷狀態(tai)(tai)電(dian)(dian)梯(ti)(ti)裝(zhuang)(zhuang)(zhuang)(zhuang)(zhuang)潢(huang)(huang)（輕裝(zhuang)(zhuang)(zhuang)(zhuang)(zhuang)載(zai)，超載(zai)下(xia)游）和練級才(cai)漸漸慢的(de)電(dian)(dian)梯(ti)(ti)裝(zhuang)(zhuang)(zhuang)(zhuang)(zhuang)潢(huang)(huang)，曳引機(ji)(ji)(ji)的(de)狀態(tai)(tai)制動(dong)(dong)(dong)功率(lv)。過程中(zhong)的(de)電(dian)(dian)機(ji)(ji)(ji)繞組寫入機(ji)(ji)(ji)械能(neng)(neng)(neng)轉化為電(dian)(dian)能(neng)(neng)(neng)，不安(an)裝(zhuang)(zhuang)(zhuang)(zhuang)(zhuang)電(dian)(dian)梯(ti)(ti)裝(zhuang)(zhuang)(zhuang)(zhuang)(zhuang)潢(huang)(huang)電(dian)(dian)梯(ti)(ti)裝(zhuang)(zhuang)(zhuang)(zhuang)(zhuang)潢(huang)(huang)節能(neng)(neng)(neng)設備，能(neng)(neng)(neng)源(yuan)消(xiao)費的(de)這部分，二是(shi)在(zai)制動(dong)(dong)(dong)和耐熱性(xing)消(xiao)費。這兩種方(fang)法不僅浪費了大量的(de)能(neng)(neng)(neng)源(yuan)，同時也產生了大量的(de)熱量，導致機(ji)(ji)(ji)房升溫。為了保證在(zai)電(dian)(dian)梯(ti)(ti)裝(zhuang)(zhuang)(zhuang)(zhuang)(zhuang)潢(huang)(huang)的(de)正(zheng)常運行(xing)(xing)，而(er)(er)且還(huan)需(xu)要增加空調或(huo)冷卻風扇(shan)，從而(er)(er)進一步(bu)增加了能(neng)(neng)(neng)量消(xiao)耗。電(dian)(dian)梯(ti)(ti)裝(zhuang)(zhuang)(zhuang)(zhuang)(zhuang)飾廠家使(shi)用(yong)逆(ni)變(bian)器(qi)的(de)交流(liu)-直(zhi)流(liu)-交流(liu)工(gong)作，發(fa)電(dian)(dian)的(de)曳引機(ji)(ji)(ji)為直(zhi)流(liu)電(dian)(dian)力狀態(tai)(tai)，并使(shi)用(yong)能(neng)(neng)(neng)量反饋(kui)裝(zhuang)(zhuang)(zhuang)(zhuang)(zhuang)置(zhi)和本地網逆(ni)變(bian)器(qi)的(de)是(shi)在(zai)與電(dian)(dian)壓(ya)相位(wei)，交替與DC的(de)頻率(lv)給回當前對交流(liu)電(dian)(dian)網的(de)使(shi)用(yong)，達到(dao)節能(neng)(neng)(neng)的(de)目的(de)附近的(de)其他(ta)電(dian)(dian)器(qi)設備。目前，曳引機(ji)(ji)(ji)的(de)再(zai)生功率(lv)反饋(kui)控制技術(shu)是(shi)普通電(dian)(dian)梯(ti)(ti)裝(zhuang)(zhuang)(zhuang)(zhuang)(zhuang)潢(huang)(huang)電(dian)(dian)能(neng)(neng)(neng)回饋(kui)裝(zhuang)(zhuang)(zhuang)(zhuang)(zhuang)置(zhi)相當成??熟，可以(yi)(yi)實現在(zai)安(an)裝(zhuang)(zhuang)(zhuang)(zhuang)(zhuang)后(hou)節電(dian)(dian)20％?45％，同比增長50.56個百分點。
