No , there will be no overvoltage , because the power of the magnetic field will be reduced by the regulator , and therefore the voltage produced by rotating the armature within this field will be reduced .
A dynamo works by rotating a coil of wire - the armature - between the poles of a magnet . This induces a flow of electricity through the armature . In order to produce a decent magnet the pole pieces of the magnet are themselves wound with wire . Feed a current through these windings - the field windings - and you have an electro-magnet . The strength of the magnetic field between these pole pieces depends on the strength of the current fed through field windings . So - vary the field current - vary the field strength - vary the output of the dynamo .
Have you got that down ?
Now , for your homework ............. . .
