一般来说，几百瓦以下的用一只手就可以拧动了，正常的电机拧的时候助力比较均匀。就算有磁阻转矩，也是有明显的周期性，也就是每隔固定角度力矩波动。还有就是可以用手转一下正常的电机(假设你手里有好的同型号电机)，两种电机的手感应该基本一样，如果拧的时候就不正常，那就是电机有故障了。这种测试一般可以发现机械故障或者相间短路故障。

　　还有就是用万用表可以做大部分的电机检查了，简单的说就是测三相线电阻，ABC三相，你测一下AB、BC、CA之间的电机，这三相电阻应该基本一样或者差别很小。同样的，地方式也是用一个正常的电机比较，这三相电阻如果与正常电机一样，那说明定子绕组应该没什么大问题（如果有虚焊或者虚接或者绝缘不足等问题，就得上别的手段）。如果不一样的，比如说出现无穷大或者很大的阻值，说明绕组有短路的，或者出现很小的阻值，说明绕组有断路的。如果相电阻非常小，不方便测试，也可以测电感，道理与电阻一样。
