Please enlighten: DC/AC Motors and function

I'm beginning some projects, entirely for my own education and amusement. Among these 'Saturday' projects, I'll be creating a DC or AC motor of some design, from scratch, and have a few questions:

1) Can a brushless DC motor be used as a generator? ( I am referring to the "hall" effect 'brushless' simple motor, as illustrated at simplemotor.com). Can anyone see what mods. it would take to make it a generator, if at all possible?

2) Does anyone know of a concise source on modifying the internals of a car-type alternator to produce DC?

3) Finally, how about a good general source of information for the newbie motor builder.

T.I.A. for all good help.

-------- Take the motor of your reference, remove the electronics and sensor, turn the rotor and you will have an AC generator- this is even simpler than the "Hall effect" motor.

----------------

---------- The car alternator produces AC and there is a rectifier bridge built into the casing of the alternator to convert this to DC -that is- it is already done.

---------------

---------- Read up a bit about the principles of operation of basic motors. For example, a simple DC motor is simply an AC motor with a synchronous switch such as the Hall effect device or the conventional commutator. A simple AC induction motor can be made with 2 coils, a capacitor and something conductive like a beer can (empty it first) on a spindle as a rotor. You may be able to dispense with the capacitor and one coil if you start the motor manually. If you look at a picture of the construction of an induction motor you will see an iron core and stator. A simple version is the "shaded pole motor" An iron core is needed for good performance of any motor.

I can recommend this site.

They will have a couple of useful books in the electronics sections.
