如果可以拆開，那就在無關要的地方刮開線看看，看完后之后再用高溫膠布粘好就行。如果不能拆開的，就對比一下線圈電阻 ，鋁芯要比銅芯的電阻大一點。

一、銅的導電性能比鋁的好

銅線的載流量是每平方6安培，鋁線5安培，所以鋁線電機長時間工作容易發熱，當然一般外殼溫度保持在90度內問題也不大，整體性能不如銅線電機穩定，一分錢一分貨。

鋁芯電機的功率比銅芯小很多，載流量小所以容易發熱。一般鋁線比銅線功率小百分之20左右。

二、純銅線電機當然更

鋁比銅電阻大一點，在使用中發熱量較高，很容易燒壞電機。而且鋁和銅焊接是不能自然融合，電源線連接點也容易造成燒壞，所以一般鋁線電機水泵的整機壽命遠低于純銅線電機水泵使用壽命。     

三、純銅線電機更省電

電路元件的電阻大小與發熱大小成正比例關系，電阻大則發熱會大。      

四、純銅芯電機噪聲更小

當噪聲平均每提高3分貝，噪聲的能量就會增強一倍。鋁線電機噪音比銅線電機大約高7分貝，所以鋁線電機噪聲比銅線電機噪聲大兩倍還多。純銅線電機水泵整機噪聲經過測試僅為58分貝。
