電(dian)子(zi)扇(shan)馬達電(dian)機(ji)電(dian)子(zi)風(feng)(feng)扇(shan)的工(gong)作(zuo)(zuo)原(yuan)理(li)是汽車電(dian)子(zi)風(feng)(feng)扇(shan)由恒(heng)溫(wen)(wen)(wen)器(qi)(qi)控制。當水(shui)溫(wen)(wen)(wen)上升到上限時，溫(wen)(wen)(wen)控器(qi)(qi)接通電(dian)源(yuan)，風(feng)(feng)扇(shan)開(kai)始(shi)工(gong)作(zuo)(zuo)。當水(shui)溫(wen)(wen)(wen)降(jiang)至下限時，溫(wen)(wen)(wen)控器(qi)(qi)關(guan)閉電(dian)源(yuan)，風(feng)(feng)扇(shan)停止(zhi)工(gong)作(zuo)(zuo)。功能是冷卻發(fa)動(dong)機(ji)水(shui)箱(xiang)。
以下(xia)是(shi)電子(zi)風扇不轉的(de)原(yuan)因:
1。電機潤滑不良，電風扇不轉，安(an)裝扇葉后無法拖(tuo)動(dong)電機；
2、電(dian)機(ji)過熱，電(dian)機(ji)過熱還會造(zao)成電(dian)機(ji)負(fu)載(zai)能力變差，電(dian)機(ji)有效(xiao)功率變低，導(dao)致無法驅動負(fu)載(zai)；
3.當(dang)啟動(dong)(dong)(dong)電容(rong)容(rong)量變小(xiao)時，電容(rong)容(rong)量會變小(xiao)，導(dao)致電機啟動(dong)(dong)(dong)轉矩變小(xiao)，無法驅(qu)動(dong)(dong)(dong)負載；
4.電(dian)(dian)機(ji)使用(yong)時間過長。電(dian)(dian)風扇(shan)用(yong)久了(le)，電(dian)(dian)機(ji)會磨損，電(dian)(dian)機(ji)的軸套也容易燒壞(huai)。如果長時間使用(yong)電(dian)(dian)機(ji)，電(dian)(dian)機(ji)內阻也會增大，負載能力下降，導致(zhi)無法帶動(dong)扇(shan)葉轉(zhuan)動(dong)。
