I have a small dc motor that puts out 90 volts at 6000 rpm.I have
hooked it up to # of things(hand crank,Pedal,etc}. I have just tried
it with a gas 3.5 hp lawnmower engine. It actually put out a lot of
voltage ,enough to run a 110volt ac drill.My problem is I would like
to use this setup but am afraid of dealing with this high a voltage
Dc. I basically want a generator to charge a battery bank at my
cottage.How do I regulate this voltage down to the 13-18 volt range
that I can use for charging 12 volt batteries? Will a voltage
regulator off of an automobile work? alternators are ac do regulators
work the same for ac and dc current?
It may be easier to connect your engine to an automotive alternator that has
a built in regulator and do it that way.
