I was sitting at a RR crossing one day when I had a bright idea. . . . .

Has anyone ever powered a GT with an engine driving a generator which drives an electric motor hooked to the rear? Kind of an electric version of a Case hydraulic drve.

Isn't that what that lumber yard 4 wheeler-tractor was in old posts?  Seems it was a generator when stopped, but used electric motors to move/drive?  The engine just ran the gen then?  But, not diesel then, ha!

Like a diesel generator instead of batteries on those electric tractors ?

I considered doing it in one of my electric conversions... But abandoned that when I got a GE Elec Trak.

You're correct. Electric drive motors powered by a gas generator. It was called the Raven. They were off the market but I thought I read somewhere that they were being reintroduced?

  Wouldn't a DC generator be required?

For something small you would probably want DC like old diesel locomotives.simple system but most of the big stuff nowdays  uses AC and controls the speed with Variable frequency.

Those motors also have reversing windings in them to reverse the direction of travel. Technically if you can find a DC generator that can handle the load, a DC motor can produce more torque then an AC motor. So for a smaller scale DC may be the better choice & to find the parts just find an electric golf cart. If I remember correctly some of the gas powered golf cart use that type of set up with the gas motor turning a generator that powers an electric motor drive.

It would be a cool idea. Most likely be a challenge to get all the bugs out.

Yes the raven is like this. It wasn't pulled off the market though, there were a few problems in version one that were worked out and a version two was created. :)

I have seen the Raven at my local dealer and local Lowes. 13HP generator motor with generator under the seat and all electric drive and blade drive (no belts-3 direct drive electric motors). Only has 110 on the plugs though, no 220 for welder or such. Pricey though. Showing a tag of $4000.

Given this scenario, does a larger engine create more power? . . . Or does any engine that turns the generator at a proper RPM do the job?

If your really interested about diesel to electric or gas to electric you could look up R. G. LeTourneau. He made a lot of diesel to electric construction and special equipment in the 50's and 60's, he's pretty much considered a pioneer in the field.

My friend and I are making a little project that will have a engine running a generator to power the motors. Kinda like a locomotive I guess.
