They are on a pulley yes, but the regulator increases the "Field strength" to increase amperage output of the alternator, so when the Car needs more juice, the engine will work harder to spin the armature through the field windings.
ah, cool, thanks.

I didn't know that the mechanical resistance increased or was variable. I figured the alternator makes what it makes at all times and the electricity produced was regulated into the system a different way.
