電(dian)子(zi)扇(shan)(shan)馬達電(dian)機電(dian)子(zi)風扇(shan)(shan)的工(gong)(gong)作(zuo)(zuo)原(yuan)理是(shi)汽車電(dian)子(zi)風扇(shan)(shan)由恒溫(wen)器(qi)控制(zhi)。當(dang)水(shui)溫(wen)上升到上限時(shi)，溫(wen)控器(qi)接通(tong)電(dian)源(yuan)，風扇(shan)(shan)開始工(gong)(gong)作(zuo)(zuo)。當(dang)水(shui)溫(wen)降(jiang)至下限時(shi)，溫(wen)控器(qi)關閉電(dian)源(yuan)，風扇(shan)(shan)停止工(gong)(gong)作(zuo)(zuo)。功(gong)能是(shi)冷卻發動機水(shui)箱。
以下是電子風扇不(bu)轉(zhuan)的(de)原因:
1。電(dian)(dian)機(ji)潤(run)滑不(bu)(bu)良，電(dian)(dian)風扇不(bu)(bu)轉，安裝扇葉(xie)后無法拖(tuo)動電(dian)(dian)機(ji)；
2、電機過熱，電機過熱還會造成電機負(fu)載能力變差(cha)，電機有效功率變低，導致無(wu)法驅(qu)動(dong)負(fu)載；
3.當啟(qi)動電容容量(liang)變(bian)(bian)小(xiao)時(shi)，電容容量(liang)會變(bian)(bian)小(xiao)，導致(zhi)電機(ji)啟(qi)動轉矩(ju)變(bian)(bian)小(xiao)，無法驅動負載；
4.電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)使(shi)(shi)用(yong)時間過(guo)長。電(dian)(dian)(dian)(dian)風扇用(yong)久了(le)，電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)會磨(mo)損，電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)的軸套也(ye)容易燒壞。如果長時間使(shi)(shi)用(yong)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)，電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)內阻也(ye)會增大，負載能力下降，導致無法(fa)帶動扇葉(xie)轉動。
