Rotary AC generator

I am looking for information about suppliers of
rotary AC generators (not complete gas engine/
AC genrators). Capacity roughly 1 KW or so.

What I want is to run an electric motor/generator
with a fly-wheel to supply a couple of minutes of
electrical power when the AC power fails.

I couldn't make any reasonable hits on Google.

Thanks for any info.

Check www.harborfreight.com. They have several such generators in their
latest printed catalog so they should be available on their web site.

You will need a very large flywheel, do the math first then you will forget it
and try a battery powered sytem instead.

Turn-key systems are available (no need to DIY):
http://www.google.com/search?&q=flywheel+Active-Power
 
if your trying to keep sensitive equipment running then connect that
equippent to a UPS ( uninterrupted power source). these have batteries
which very on time you have after main power drops out but keeps from a
lost of power during unexpected power dips or short losses.
P.S. these units have betteries to roll in when the power drops out
from your main line.

It's much easier to use a battery charger, 12V car battery and a Mains
Inverter. Run your equipment from the mains inverter all the time and you
don't need any switching circuits.

Thanks for all of the responses.

I'll check into the pointers.

We had a motor-generator or MG on our old mainframe computer.
It could supply AC for only a few saeconds of power interruption.
To get a few minutes, you would need a HUGE flywheel.

Just buy a decent UPS.

Thanks for any info.

That's odd. I submitted this message over a month ago and
received various responses the next day.

Your newsgroup supplier must be very slow!

I seriously doubt if his newsgroup supplier is slow, so much as the
probability that your post was simply ignored by the more informed
readers for some time.

Your post was, in fact, rather naive and dumb. You evidently did no
research into the subject prior to posting. Then you complained abut a
poster who provided you with factual information! It's responses like
your's that discourage professional having the knowledge that you seek
from posting responses.

Any number of people who read this newsgroup could have told you that
the notion of running your generator for a minite or two on flywheel
power is ridiculous. Many others could have told you that IBM
manufactured such a system to stabilize the power fed to its computers
during the 1950s and 1960s, but that in spite of its large dog-house
size, its large flywheel energy storage mechanism was capable of
stabilizing power for only tens of milliseconds -- a few missing power
cycles.

'Nuff said, except that it wann't wise for you to criticize the one
guy that gave you credible fact!

No, it was there not long after it was posted. I guess I'm the slow one.
;-)
It popped up, and I answered it.

Thanks for the response. It just surprised me when it appeared.

The reason that I inquired was because we have very few power outages
here and I don't want to spend a lot of money on batteries just for the
once in a blue moon failure (which usually is typically only seconds
in duration).

Although I have an electronics background (until about 30 years ago
when I changed to computer programming) I don't know veru much
about motor/generator design.

Thanks again.
