電子扇馬達電機簡介

電(dian)(dian)(dian)子扇(shan)馬達電(dian)(dian)(dian)機(ji)(ji)電(dian)(dian)(dian)子風(feng)(feng)扇(shan)的工(gong)作原理是(shi)汽(qi)車電(dian)(dian)(dian)子風(feng)(feng)扇(shan)由恒溫器控(kong)制。當水(shui)溫上(shang)升到上(shang)限(xian)(xian)時，溫控(kong)器接通電(dian)(dian)(dian)源，風(feng)(feng)扇(shan)開始工(gong)作。當水(shui)溫降至(zhi)下(xia)限(xian)(xian)時，溫控(kong)器關閉(bi)電(dian)(dian)(dian)源，風(feng)(feng)扇(shan)停止工(gong)作。功能是(shi)冷卻發動機(ji)(ji)水(shui)箱(xiang)。

以下是電子(zi)風扇不(bu)轉(zhuan)的原(yuan)因:

1。電(dian)機潤滑不良，電(dian)風扇(shan)不轉(zhuan)，安裝扇(shan)葉后無法拖動電(dian)機；

2、電機過熱(re)，電機過熱(re)還會造成(cheng)電機負(fu)載(zai)能力變差(cha)，電機有效功率變低，導致(zhi)無(wu)法驅動負(fu)載(zai)；

3.當啟動(dong)電容容量變小時，電容容量會變小，導致電機(ji)啟動(dong)轉矩變小，無法驅動(dong)負載；

4.電(dian)(dian)(dian)機(ji)使用時間(jian)過(guo)長。電(dian)(dian)(dian)風扇用久(jiu)了(le)，電(dian)(dian)(dian)機(ji)會磨損(sun)，電(dian)(dian)(dian)機(ji)的軸套也容易燒壞(huai)。如果長時間(jian)使用電(dian)(dian)(dian)機(ji)，電(dian)(dian)(dian)機(ji)內阻也會增大，負載能力下降，導致(zhi)無法(fa)帶(dai)動(dong)扇葉轉動(dong)。
