    What's the part called that converts spinning, rotor, motor power into electricity?

    If I were to buy one what would I call it?

    Modern cars use an alternator, older ones may have a generator.

    Whats the difference? An alternator is a small generator isn't it?

    Alternator, generator, dynamo, magneto... then there are also a pile of electrostatic machines too...


    If you were to buy one, the question is; what do you want it to do?

    High voltage, high current, low voltage, low current, AC, DC, pulsed..?
