I had thought of using a stepper motor as an electrical source for some time but supposed it would be less than suitable.
I saw a video that I think Jim Dodson had made using a stepper motor and a bridge rectifier to light a DC bulb so I had some time and a small stepper motor so why not give it a try.
I mounted it on my V-Twin with a 1 to 1 gear ratio and hooked the stepper windings in series.
I was surprised to say the least.
At 1400 rpms the unloaded output was 120 volt A/C and with a 7 watt load it only dropped to 90 volts.
I believe the cycles per second are in the thousands so next week a friend of mine will bring over his scope so we can do some more tests.
And here is a short video.
Thanks for looking
