Remember guys maximum torque means minimum magnetic flux!!!
Cause $F=IlB$ is kinda different to $\Phi =BA$
If split in split ring commutator is too short/long, then you get issues (shorting, friction).
Torque graph over one rotation, 1 coil, 2 sections of commutator
Torque graph over one rotation, 2 coils, 4 sections of commutator
What this might look like from a side on view (viewing from perspective of commutator)
How to make torque more consistent(smooth):
Exam content only up to AC generators.
