電(dian)(dian)(dian)子(zi)(zi)扇(shan)(shan)馬達電(dian)(dian)(dian)機電(dian)(dian)(dian)子(zi)(zi)風扇(shan)(shan)的工(gong)作原理(li)是(shi)汽車(che)電(dian)(dian)(dian)子(zi)(zi)風扇(shan)(shan)由恒(heng)溫(wen)器(qi)(qi)控制。當水溫(wen)上升到上限時，溫(wen)控器(qi)(qi)接(jie)通電(dian)(dian)(dian)源，風扇(shan)(shan)開(kai)始工(gong)作。當水溫(wen)降至下限時，溫(wen)控器(qi)(qi)關閉電(dian)(dian)(dian)源，風扇(shan)(shan)停(ting)止(zhi)工(gong)作。功(gong)能是(shi)冷卻發動機水箱(xiang)。
以(yi)下是(shi)電子風(feng)扇不轉的原因:
1。電機潤滑不良，電風(feng)扇不轉，安裝扇葉后無法拖(tuo)動電機；
2、電(dian)(dian)機(ji)(ji)過熱，電(dian)(dian)機(ji)(ji)過熱還會造成電(dian)(dian)機(ji)(ji)負載能力變差(cha)，電(dian)(dian)機(ji)(ji)有效功率變低，導致無法驅動(dong)負載；
3.當啟動電(dian)(dian)(dian)容(rong)容(rong)量(liang)變小時(shi)，電(dian)(dian)(dian)容(rong)容(rong)量(liang)會變小，導致電(dian)(dian)(dian)機啟動轉矩變小，無法驅動負載(zai)；
4.電(dian)機(ji)使(shi)用時間(jian)過長。電(dian)風扇用久(jiu)了，電(dian)機(ji)會(hui)磨損，電(dian)機(ji)的軸套(tao)也(ye)容易燒(shao)壞。如果長時間(jian)使(shi)用電(dian)機(ji)，電(dian)機(ji)內(nei)阻也(ye)會(hui)增大，負載能力下降，導致(zhi)無法帶動(dong)扇葉轉動(dong)。
