Here is a somewhat lengthy but interesting series on rewinding a common alternator unit, these are pretty all much all the same in that they use counteracting windings and resistance to give some automated voltage regulation in a passive sense. For those intrepid souls that are willing to try this, its interesting to note the minimal need of anything other than the ability to count and a large amount of patience.

Alternatively, only the main windings need be wound, and any voltage regulation can be achieved via an electronic AVR acting directly on the rotor windings. This one above is a 4 pole, but identical methods are used for 2 pole designs.
Seems to me its a very productive way to spend an evening or two in front of the fire.
