Hence the reason I'm here asking for information; I don't know. I have no idea how a controller would work, although I'm pretty certain that at least the railroads have done it in controlling speed.
I'm talking about utilizing my already 44mpg 4cyl diesel engine to direct-power a 20kW 240V generator head, and then wiring through a controller, directly to a 240V motor that will produce at least the same 58hp as my diesel engine does.
I won't be adding any weight, because once I take out the transmission and put the generator head in its place, I will have almost the same weight. This mini-pickup weighs about 2600lbs.
I won't be adding batteries of any kind, because I will retain my original 12V electrical system for my p/u, along with my vacuum assist braking system, complete with discs and drums.
I am only changing the element that provides power to turn the rear axle; the drive motor. The drive motor will be attached to the yoke at the rear axle, in the place of where the drive shaft is now, to turn the axle. This just seems to simple to me. All I'm after here is for someone who actually knows how all of this works, to provide me with links to research the information so I can accomplish this, if it can actually even be done.
I see freight trains moving daily, so I know I'm not out of the ballpark here.
