The idea is still very abstract...
I'm looking into a small power source that I can use to power a robot. It's going to use a lot of juice... 12V at somewhere in between 20-50amps ... depending on how many actuators are going at once. If I was to pick up a Nitro engine and couple a DC motor to the shaft and use it as a generator...
When I start loading the circuit obviously the mechanical resistance of the motor goes up, thus loading the nitro engine. At some point, the engine will stall. Does anyone know the best way to operate the system over the whole "load range"? The first thing that comes to my mind is some sort of dynamic transmission or gearbox...
