電(dian)子扇(shan)馬達(da)電(dian)機電(dian)子風(feng)扇(shan)的(de)工(gong)作(zuo)原理是汽車電(dian)子風(feng)扇(shan)由恒溫(wen)(wen)(wen)(wen)器控(kong)制。當水溫(wen)(wen)(wen)(wen)上(shang)升到上(shang)限(xian)時，溫(wen)(wen)(wen)(wen)控(kong)器接通電(dian)源，風(feng)扇(shan)開(kai)始(shi)工(gong)作(zuo)。當水溫(wen)(wen)(wen)(wen)降至(zhi)下限(xian)時，溫(wen)(wen)(wen)(wen)控(kong)器關閉電(dian)源，風(feng)扇(shan)停止工(gong)作(zuo)。功能是冷卻發動機水箱(xiang)。
以下(xia)是電子風扇不轉的(de)原因:
1。電機(ji)潤(run)滑不良，電風扇不轉，安裝扇葉后(hou)無法拖動電機(ji)；
2、電機(ji)過(guo)熱，電機(ji)過(guo)熱還會造成電機(ji)負載能(neng)力(li)變(bian)差，電機(ji)有效功率變(bian)低，導(dao)致無法驅動負載；
3.當啟動電(dian)容(rong)容(rong)量(liang)變(bian)小(xiao)時，電(dian)容(rong)容(rong)量(liang)會變(bian)小(xiao)，導致電(dian)機啟動轉矩變(bian)小(xiao)，無法驅動負(fu)載；
4.電(dian)(dian)(dian)機(ji)(ji)使(shi)用(yong)時間(jian)(jian)過長(chang)。電(dian)(dian)(dian)風扇(shan)用(yong)久了(le)，電(dian)(dian)(dian)機(ji)(ji)會磨損，電(dian)(dian)(dian)機(ji)(ji)的軸套也容易燒壞。如(ru)果長(chang)時間(jian)(jian)使(shi)用(yong)電(dian)(dian)(dian)機(ji)(ji)，電(dian)(dian)(dian)機(ji)(ji)內阻也會增大，負(fu)載能力下降，導致(zhi)無法帶動(dong)扇(shan)葉轉動(dong)。
從前(qian)面看，車(che)子的鍥形大(da)燈與直豎格(ge)柵(zha)依然沿用斯柯達傳統的硬朗造型，有歐(ou)雅的影子。繞到側面，車(che)頂由大(da)幅傾斜的a柱延伸到弧線狀(zhuang)的c柱，前(qian)面保險杠(gang)低垂，后面車(che)尾線條簡潔，完(wan)全是現代轎車(che)的流行風格(ge)。
