Electric OU: Tuning the Bedini NP/Schoogirl Motor Base Resistance
I put a light bulb, a fixed resistor, and a potentiometer in as substitute for the base resistance (680 or 470 ohms in my circuit) in order to see what happens and how the performance depends on this resistance. There is definitely a “sweet spot” or operating range. Too much resistance and you get the multiple spikes and the motor doesn’t run or start. Too little resistance and your RPMs decrease and your high voltage goes away. The sweet spot is about 1/3 of the way back towards the multiple spikes setting. For mine, I think I’ll just put a 330 ohm fixed resistor in there and call it good.
