Hello all, this a total noob question..I have a 6.5 kw generator and I also have a poratable Lincoln Welder. It has 2, 12 volt batteries that start the engine and are also kept charged while in use. I was thinking that the generator part of the welder would make a great motor espestially since it was free. I also have a regular 6.5KW gerenator that i could use....WILL either of these work and if so what kind of controller if any would I need? My main goal is to take a 2000lb car and drive it to work a few miles away at 60mph. I have 2.8 mile commute but the weather here is nasty over half the year so a bike is out of the question and I have a freeway in my way. The only way to work is an the 55+mph freeway. My problem is that I have skills but no money. I have cars that need motors and the generators. Any help to start this process would be great. Also I would like to ad that I am a High School Shop Teacher so I have quite a shop and tons of skill just not experience in this area. This will be part of my auto shop class next year if I can get this together.
Thanks in advance,
David

Hi kine,

While technically possible (all motors can generate and all generators can motor, if properly excited), this is a bad idea with the equipment you reference. These generators likely will make very poor motors and I suspect would suck for your EV. You're much better off finding a used forklift motor. Check out the sticky in the motors forum.

Why the poll

I have the same question, but my genny is a 10Kw 3-phase military powerplant. In some of the reading I have done it says that 3-phase motors can be used to incorporate Regenerative Braking. Or does this require a prohibitively expensive controller or some other hurdle?

I imagine the OP was intending to get several opinions hence the "Poll". I would like to hear from others.
