I think it makes sense. The commutator selects a winding. The

on an AC Motor are no permanent S and N poles ;(
Its because Alternating Current = AC!

Yeah but, it's a series motor so that means it can operate
on AC or DC..

As for the communtator being out by 1.5" or so, that isn't anything
to worry about because in the first short running time that should
smooth out, unless there is some bearing play? You really don't
want that.
