On your web page you ask why they made the commutator so small.
I think the most obvious-by-far reason is to reduce the amount of wear on the
contacts due to friction. By making the radius of the commutator cylinder
small, they reduce the linear velocity at the point where the contacts touch
it. The size they chose is probably the smallest that conducts the needed
amount of current and can be built the the type of machinery available.
