I'm looking for a way to make a cheap and easy to build (by theory) controller.
I've poked around on the forums and really liked the idea of the mechanical PWM controller (
) but it looks like there are too many limitations for an EV application.
This sounds like a dumb question to me, but what the heck. Is there any reason why I can't just put a large potentiometer in series with the batteries and the motor and use that as my throttle to control the power output?
Have there been any other feasible attempts to build a simple (DC motor only) controller for EV applications?
My specialty is ME, not EE so try to explain it in a way that will make sense to me!
