逆时针和顺时针，是要从什么方向来看，这只是看的方向的问题，从这个方向是顺时针从另外一个方向就是逆时针，没有人规定电机总是顺时针转的，以三相异步电机为例，任何两条相线接法颠倒了，电机会立马反向，也就是原来所谓的顺时针，会变成逆时针旋转了。
对电机旋转方向的术语是有国标规定的，只称为顺时针还是逆时针，但是没有谁规定电机一定要顺时针转。如果只有一个轴伸，或不同直径的两个轴伸，从轴伸端看（对两个轴伸的看大直径端）；如果有两个相同直径轴伸的，或者没有轴伸，则从有换向器或滑环端看；如果一端有换向器而另一端有滑环，则从滑环端看。电动机的转向是顺时针的称顺时针旋转，逆时针的称逆时针旋转。
发动机大都是顺时针旋转的，别把发动机和电机混淆了，发动机顺时针转的主要原因如下：按照传动系统的设计，面对风扇当发动机顺时针运转时，扭矩经过变速箱，传动轴，驱动桥，最终到达车轮上刚好是使前进的方向。在发动机刚开始问世的时候，起动根本不是靠起动机，一般都是靠人力起动。一般人都习惯用右手，所以在设计发动机的时候，考虑到人站在发动机前面，使用右手方便，所以就设计成顺时针方向了。大多数发动机都是如此，也有少数赛车或者航空发动机是逆时针运转的，具体要看需要了。电机节能智能电机节电设备。
