Alternator Question

[Tsunami]

If hooked up to a high speed (hopefully quiete) electric motor (12v)
would/should a standard car alternator normally be able to run itself + some
extra amperage (hopefully 20a)?

Sure, but only if it's a *really* fast motor, which probably won't be very
quiet unfortunately - you might be able to wrap it in foam, or some
newspapers perhaps.

The alternator will need to be a 24v unit from a truck or similar so you
have some volts left over from driving the motor.

Good luck!

Take your idea down to the patent office. See how far you get.

12V X 20A = 240 Watts. Try using a small petrol-powered generator instead.

Should handle it easily, but you'll need to run the motor backwards
for at least 15 minutes every hour -- depending on the conversion
efficiency. Assuming of course that the motor is powered by an
accumulator (car battery for example).

A chain drive with pedals attached might be the way to go.

Have a look at the data plate if it has one. It should have a current rating
on it. Or you could find the manual for the car that it came from.
20 Amps doesn't sound excessive for a car alternator.

Read the OP again. He actually wants to make a perpetual motion machine. An
admirable goal, albeit pointless.

No , what comes out requires more to go in , input 2kw = output depends
on efficiency but maybe 1500 watts.. sorry not going to be perpetual .

Ahh. Ok.
I thought he had just badly worded the question and assumed he wanted to run
a alternator off a motor.

A simple way to generate endless energy is to ask a silly question on a news
group and watch the hot heads burn perpetually. If anything the argument
increases exponentialy and snowballs.

Marty again.

If he does make lots of money, and the universe doesn't explode 'cause he
buggered up the conservation of energy thing, I want my cut of the dosh for
my truck alternator idea.

If you used a 12v motor that was big enough to run an alternator, say
35 amp alternator and use the output to charge the battery powering
the 12v motor, you would invent a rapid battery flattening device.

Perhaps you should get into wind power if you have a brother called
typhoon.
