YE2系列三(san)(san)相(xiang)異(yi)步(bu)電(dian)(dian)(dian)(dian)動(dong)機是指通(tong)用(yong)普通(tong)型三(san)(san)相(xiang)異(yi)步(bu)電(dian)(dian)(dian)(dian)動(dong)機具有高(gao)(gao)1效(xiao)率(lv)的(de)(de)電(dian)(dian)(dian)(dian)機。高(gao)(gao)1效(xiao)節能電(dian)(dian)(dian)(dian)機采(cai)用(yong)新型電(dian)(dian)(dian)(dian)機設計(ji)、新工(gong)藝(yi)及(ji)新材料，通(tong)過降低(di)電(dian)(dian)(dian)(dian)磁能、熱能和機械能的(de)(de)損耗，提高(gao)(gao)輸出效(xiao)率(lv)。與普通(tong)電(dian)(dian)(dian)(dian)機相(xiang)比，使用(yong)高(gao)(gao)1效(xiao)電(dian)(dian)(dian)(dian)機的(de)(de)節能效(xiao)果(guo)非常明顯，菏澤YE2系列三(san)(san)相(xiang)異(yi)步(bu)電(dian)(dian)(dian)(dian)動(dong)機，通(tong)常情況下效(xiao)率(lv)可平均提高(gao)(gao)4%。重量基本(ben)相(xiang)同。高(gao)(gao)1效(xiao)三(san)(san)相(xiang)異(yi)步(bu)電(dian)(dian)(dian)(dian)動(dong)機從設計(ji)、材料和工(gong)藝(yi)上采(cai)取措施(shi)，例如采(cai)用(yong)合理的(de)(de)定(ding)、轉子(zi)槽數、風扇參數和正(zheng)弦繞(rao)組等措施(shi)，降低(di)損耗。

三(san)相(xiang)異步電動機空(kong)載(zai)電流過大可能有下列原因(yin):

1. 電源電壓太(tai)高:設(she)法降(jiang)低電源電壓。

2. 電(dian)機本身氣(qi)隙太大:仔細檢查氣(qi)隙大的原(yuan)因，相(xiang)應處理。

3. 定子繞組(zu)匝(za)數(shu)不(bu)夠(gou):重新繞制。

4. 電動機裝配不當(dang):仔細檢查各(ge)部位置，重新(xin)裝配。

5. Y形(xing)接(jie)(jie)(jie)線(xian)誤(wu)接(jie)(jie)(jie)成(cheng)△形(xing)接(jie)(jie)(jie)線(xian):查清改換接(jie)(jie)(jie)線(xian)方式。

6. 對于舊電動機，由于硅鋼片(pian)老化或腐蝕，磁場強(qiang)度減弱而。

7. 造成空載電(dian)流太大.如(ru)果空載電(dian)流過大，YE2系列三相(xiang)異步(bu)電(dian)動機(ji)直(zhi)銷，則(ze)應重新繞線.對小(xiao)型(xing)電(dian)機(ji)只要不(bu)10. 超過50％的額定(ding)電(dian)流，就可繼續使用。

  YE2電(dian)機在未接(jie)通電(dian)源(yuan)之前，轉(zhuan)(zhuan)子(zi)是靜止不動(dong)(dong)的(de)。當電(dian)動(dong)(dong)機的(de)定(ding)子(zi)繞組(zu)通入(ru)三(san)相交流電(dian)后，在定(ding)子(zi)繞組(zu)中(zhong)便(bian)形成了旋(xuan)轉(zhuan)(zhuan)磁(ci)(ci)(ci)場。假定(ding)旋(xuan)轉(zhuan)(zhuan)磁(ci)(ci)(ci)場按順時針方(fang)(fang)(fang)(fang)向(xiang)(xiang)旋(xuan)轉(zhuan)(zhuan)，YE2系列三(san)相異步電(dian)動(dong)(dong)機報價，則旋(xuan)轉(zhuan)(zhuan)磁(ci)(ci)(ci)場與(yu)轉(zhuan)(zhuan)子(zi)就有相對運動(dong)(dong)，轉(zhuan)(zhuan)子(zi)導(dao)線(xian)(xian)中(zhong)將產生感應電(dian)動(dong)(dong)勢。現假設旋(xuan)轉(zhuan)(zhuan)磁(ci)(ci)(ci)場不轉(zhuan)(zhuan)，相當于轉(zhuan)(zhuan)子(zi)繞組(zu)沿逆時針方(fang)(fang)(fang)(fang)向(xiang)(xiang)旋(xuan)轉(zhuan)(zhuan)而(er)切(qie)割磁(ci)(ci)(ci)力(li)線(xian)(xian)，按照右手(shou)定(ding)則可以確定(ding)，轉(zhuan)(zhuan)子(zi)上半部導(dao)線(xian)(xian)的(de)感應電(dian)動(dong)(dong)勢方(fang)(fang)(fang)(fang)向(xiang)(xiang)是向(xiang)(xiang)外(wai)的(de)，下半部導(dao)線(xian)(xian)的(de)感應電(dian)動(dong)(dong)勢方(fang)(fang)(fang)(fang)向(xiang)(xiang)是向(xiang)(xiang)內的(de)。
