So i guessed right. Furthermore it's proportional to stator winding count and depend on field current. For low field currents, the generator voltage is also proportional to field current, up to rotor saturation.
I just remember \[rpm = (f_{AC} / count_{statorpolepairs}) ~~ \cdot ~~ 60 = (f_{AC} / count_{statorpoles}) ~~ \cdot ~~120 \].
Don't know how the number of turns in the windings goes in there. Only know the more turns of wire the smaller the KV-number, i.e. the slower the motor will turn, i.e. the more voltage will be required to reach the same motor (angular/rotating) velocity.
