normal diodes are too inefficient. you lose 2V per bridge rectifier. you should use schottky diodes like the 1N5820.

I missed haow many watts did you draw"???

Stepper motors make just about the worst, most inefficient electrical generators available. Ever noticed how difficult they are to turn, even with no electrical load connected? That's energy lost, even before you've done any useful work.

I invented a breakthrough energy source that contradicts the law of energy conservation. I have a PROOF that there are electrodynamic phenomena that contradict the law of energy conservation. I am looking for $300 000 for a prototype and for $3M for patents. Making a 6 kW generator will cost $1200 in mass production, value of energy produced yearly $5400.

That is so cool.

less diodes= less loss(.6v a diode!), so fewer rectifiers should provide more output.
Maybe you could only use 2 diodes using the full winding? (assuming the wiring phase is right)

I chucked a stepper into a drill - at highest speed, it put out an astounding 220+ volts AC. Step that down with a transformer, voltage goes down but current goes up.

Thank you, a very interesting video, its amazing what these small stepper motors will put out, do you know of a site on the web that shows wiring diagrams on how to rectify stepper motor output please, regards Nigel aka Doc Cox

some stepper motors. you can get 6+volts from only 200rpm...
harryman11 (November 30, 1999 at 12:00 am)
why use a stepper motor instead or a regular generator set up is there an advantage, higher voltage? |
