- At very low rpm, alternators don't create as much
- power. Alternators are AC motors (and cheap ones at that)
- and do not create the same 'power' at all rpms. At very high
- rpm - the current can also be too high and destroy the
- diodes or destroy the windings.
- I believe most airplane atlernators use a transmission
- or some type of electronic control to keep power output
- nearly constant (I know US fighter aircraft operate at 400 Hz
- to allow minturization of the electronic components).
