Hi

I am wondering about one thing. When we have single phase AC motor with 2 windings, one opposite another connected with each other why on one side we have N and in the opposite side we have S. I know that inductor provides 90 degrees phase shift but when in the opposite looks like having 180 degrees phase shift. Don't really know why is that

Regards

Here is the method of rotating a AC induction motor with the 'induced' field in the rotor bars that then are attracted to the pole piece to provide rotation, as one bar moves out of the field, the next moves in.

Hi

Thanks for the reply but what I dont know is how the rotating field of the stator is changing in the way it produces N and S on opposite side. So i.e. when the sine wave is raising for example left stator is N and right is S. Then it changes other way round according to the frequency of the current. How this happens that we have N and S at the same time? Looks like there is 180 degrees phase shift?
