I don't see 180 commutation shortening electrical pathways just when they were fed

rew with two coils being powered instead of one I see the motor would have two iron teeth being magnetized and on a slow moving heavily loaded skateboard the motor would maybe even have double the torque output before magnetic saturation of the iron as there's now double the amount of iron, no? And this follows the same logic that a delta motor would be able to produce more torque before saturation as it seems to have all teeth electrified while the wye is just 2/3. Everyone says they perform the same but if the amount of teeth is truly different it makes sense. But maybe isn't really the case and black transformer magic is going on and ...how many teeth are magnetized?

the D and Q field vectors of a spinning motor must be seen to know whats going on. need a moving diagram to visualize and then we can talk about something for sure.
