電(dian)(dian)子(zi)扇馬達電(dian)(dian)機電(dian)(dian)子(zi)風(feng)扇的(de)工(gong)作(zuo)原理是汽車電(dian)(dian)子(zi)風(feng)扇由(you)恒溫(wen)(wen)器(qi)控制(zhi)。當水(shui)溫(wen)(wen)上(shang)升(sheng)到上(shang)限(xian)時，溫(wen)(wen)控器(qi)接通電(dian)(dian)源(yuan)，風(feng)扇開始(shi)工(gong)作(zuo)。當水(shui)溫(wen)(wen)降(jiang)至(zhi)下(xia)限(xian)時，溫(wen)(wen)控器(qi)關(guan)閉電(dian)(dian)源(yuan)，風(feng)扇停止工(gong)作(zuo)。功能是冷卻(que)發動(dong)機水(shui)箱。
以下(xia)是電子風扇(shan)不轉(zhuan)的原因:
1。電機(ji)潤滑(hua)不良，電風扇不轉，安(an)裝扇葉后無法拖動電機(ji)；
2、電機(ji)過熱，電機(ji)過熱還會(hui)造成電機(ji)負載(zai)能力變差，電機(ji)有效功(gong)率變低，導致無法驅(qu)動負載(zai)；
3.當啟(qi)動(dong)(dong)電容(rong)(rong)容(rong)(rong)量變(bian)小(xiao)時，電容(rong)(rong)容(rong)(rong)量會變(bian)小(xiao)，導(dao)致電機啟(qi)動(dong)(dong)轉矩(ju)變(bian)小(xiao)，無法驅動(dong)(dong)負載；
4.電(dian)(dian)(dian)機使(shi)用(yong)(yong)時間過長。電(dian)(dian)(dian)風扇用(yong)(yong)久了，電(dian)(dian)(dian)機會(hui)磨(mo)損，電(dian)(dian)(dian)機的軸套也容易燒壞。如(ru)果長時間使(shi)用(yong)(yong)電(dian)(dian)(dian)機，電(dian)(dian)(dian)機內阻也會(hui)增大，負載能力下降(jiang)，導致無(wu)法帶動扇葉(xie)轉動。
