不管是接正转还是反转，在接线之前我们都要先分出主线圈和副线圈。主副线圈判断方法：用万用表测电机三个端子，可以得到三组数值。其中阻值小的那一组就是主线圈，阻值大的一组就是主线圈和副线圈串联的阻值，剩下的一组就是副线圈。因为主线圈线径比副线圈粗，所以阻值比副线圈要小。正转接线方法先把电容接在阻值大的两个端子上，然后把火线和零线分别接在主线圈两端即可。反转接线方法先把电容接在阻值大的两个端子上，然后把火线和零线分别接在副线圈两端即可。

如果是有刷直流马达的话，可以让转子旋转，用万用表测输出的直流电是否正常。如果是无刷直流马达、并且三相引出，可以让转子旋转，用万用表测输出的交变电压是否正常。输出电压大小和转速成正比。单相电机这种是常见的单相电机，加了一个启动电容，今天我们来看一下怎么用万用表在不通电的情况下估测电机的好坏。首先我们要了解这种单相电机的内部结构。内部简易图电机内部有两个绕组，一个主绕组也就是运行绕组一个是副绕组也就是启动绕组。
