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?

I converted a totally rusted-out VW beetle about 25 years ago to
electric power. I got a Kaylor adaptor that holds the old
flywheel and clutch assembly and mates to the VW transaxle.
It has the 16-tooth spline to take standard jet engine starters
or starter/generators. I got a GE starter/generator. it was
rated at 400 A 28 V continuous as a generator, or 1300 A 30 V
for one minute as a starter. I don't think I ever got it up to
400A, as my trolling motor batteries didn't have terminals that
could handle that. I did cruise around the neighborhood with
it, and it worked. I had 4 90 A 12 V batteries in it, and built
a field controller that was hooked to the "gas" pedal. The only
down side to it was that particular motor was very noisy,
especially with about 30 V on the field. Without an armature
controller, the motor idled at about 3000 RPM. It would cruise
at about 30 MPH on the level at 125 A or so, and 250 would get
it ZIPPING up a steep hill. I intended to convert it to a
hybrid with a motorcycle engine, but never finished the project.
(No way could it be licensed, the body was hanging in pieces.)

Your motor doesn't have the series field connection that a
starter/generator would have, so it probably has to be run in
the shunt mode. You need to connect the field to 28 V first,
and then connect the armature to whatever power source will run it.
