Nope. He is referring to the various surplus DC generators running
around 400rpm and rated at 200, 300, or 400 amps. Very compact package,
around 7" in diameter, 14" long for the 300 amp version. Lots of info on
the web "aircraft generator welder" gets a bunch of good hits.

www.surpluscenter.com had them in their catalog as recently as last
year, don't see anything on them now.

I have a Jack & Heintz R1 400 amp aircraft generator. I'm going to the
Delta steamboat meet near Rio Vista Ca. this weekend and plan to take
the generator along to sell it as there are many do-it-yourself people
there.

The two main reasons that someone would buy this generator are to
build a welder or as a motor for an electric vehicle.

I have found several websites with directions and schematics for
building welders but have not been able to locate much info on using
this type of generator as a motor.

Does anyone know of a source of this knowlege that I can print out and
show to prospective buyers?

Hey Engineman,

Not to argue, but a 400 AMP generator is pretty large. Are you sure
that this is not a 400 CYCLE generator. 400 HZ stuff is, or at least
was, quite common on aircraft.

Can't help with making it "motor", but will say that if it gets used
that way, it will not be optimum.

Take care. Have a good trip on the Queen, and please post pix when
you get back.
