It came together for me when it was drawn out flat and straight and single phase.
For 1725RPM at 60Hz.
Draw 2 square series coils. Draw a magnet over each leg, that is 4 magnets.
like O O (coils)
annd ll ll (magnets laid N-S-N-S)
For 1150
RPM at 60Hz.
Draw 3 coils and 6 magnets.
like O O O
annd ll ll ll
North magnet cuttent goes up, South current goes down.
Rotating magnets make AC. Up down up down...
With a single phase motor, it ends up being a 2 different single phase alternators in one box.
Think about it like 2 alternators.
Seperate the start from the run winding. In your head, and in the motor.
With 3 wires, the 'center tap' is connected to 2 wires, Cut one of these, and add another output wire. Now it is 2 sets of coils and they are different (wire size and turns) from each other, so it is 2 single phase alternators in one box.
Each 'alternator' gets rectified seperatly, and the outputs are parelleled to the battery.
If the V and resistance is too high with a 4 pole, seperate and parellel the 2 coils in phase. Up side with up, down side with down. Like half the volts, double the amps.
Up until here is easy. NOW it can get confusing!
For a 3 phase rewind, lay the common coil and magnet drawings in a straight line.
Like a 12/9 or 8/6 configuration.
Maybe draw 2 papers 48cm long, 8/6, one with magnets, one with coils, each phase a different color, one paper moving past the other?
Instead of N-S-N-S, I draw up arrow ^- down arrow v- up arrow ^- down arrow v.
First look at 1 phase at a time. Then everything comes together.

Hi Zubbly!
Sorry if I totally butchered your superb explanations.
This is how I, personally, figured it out before I understood what anything meant.
