I've been staring at that "diagram" for a good 10 minutes now and all I've gotten out of it is a headache. I don't understand how the flux
interactions, as shown, would ever be able to produce any kind of torque.
This doesn't look like any AC motor I've ever studied, but the way it is represented with the coils on each end of the armature being oppositely
wound it does appear to be some sort of AC motor. According to the right hand rule for coils (wrap your hand around the coil, thumb points to magnetic
north and fingers wrap in the direction of current flow) the current through one coil flows in the opposite direction of the other, which implies some
kind of AC input to me.
What makes no sense to me is how what passes for a main field flux in this thing isn't shown to be distorted by the corresponding armature flux
through the coils. According to basic electrical theory, a current through a conductor should result in a magnetic field around the conductor, and the
direction of the magnetic flux is determined by the relative direction of the current flowing through the conductor. Magnetic lines of flux can never
touch, and when flowing in opposite directions, tend to distort each other...I don't understand why that isn't shown here.
Basically, I don't understand how the flux could behave as shown...and even as shown doesn't provide any indication of being able to result in
