电风扇的电机有5条线.分别是: 1挡.2挡.3挡.2条电容线. 一般来说,除个别电机外,3个档位的线颜色是红.蓝.绿.接电容的是黑色和黄色. 那就开始了,把电机的5条线都脱离出来.

首先,你把万用表的档位调到欧母档,红表笔接在任意的一条电容线上,黑表笔接1档.你先记下阻值,然后再测量2档和3档,正常来说,测的档位越大,它与电容线之间的阻值就越大,比如1档是70欧母.2档110欧母.3档150欧母这样.你可以记下来然后比较.

换句话说,如果你测量以上3个档位的阻值都为无穷大,或某一个档位是无穷大,那就是电机线圈烧断或某一个档位的线圈断了. 后一点,测下5条线与电机外壳,也就是所谓的"地"有没有短路.
