I was able to light a large LED with the full wave DC, but when I took out the rectifier, it wouldn't light with straight AC. Chuck
If you look at a motor, and keep in mind that it is just the reverse of a generator, things get more obvious. The higher the voltage, the faster it turns. The more poles, the faster it turns.The higher the load, the more amps.Nick
Nick, I Think you are talking about a DC Motor, speed is a function of poles and Frequency of the source for AC motor.
So, the quandry is why 3.4 DC volts would light the bulb and 3.6 AC volts wouldn't. I realize with the AC voltage, that current would only flow for 1/2 of each cycle and the other half is essentially wasted, but I would have thought that would still be enough to light the bulb. Perhaps the amount of current being produced is so small, 1/2 a cycle just isn't enough.By the way, I'm assuming when I measure the AC at 3.6 volts, that means 3.6 volts positive wave followed by 3.6 volts negative wave. Don't know if that is peak voltage or RMS.Chuck

Chuck,You are definitely are the right track. Many poles, many turns, and a steel stator will give you a reasonably high voltage output at low RPM. How are you planning on managing the cogging effect that a steel stator and permanent magnets will create?Jeff
