Shorting coil gives back more power

@Laurent,
well done, you are getting closer.

Just try to let your chopper circuit run all the time, not just in the
maximum amplitude.
This way it will produce much more ringings all the time and thus
much more output.

Regards, Stefan.

@romerouk
well done !

Can you try to put a about 5 Watts 230 Volts incandescent bulb lamp
across the cap as a load and see, if it lights up ?

Or put 50 white LEDs in series and see, if they will
light up ?
(use an additional  series resistor so you don´t  blow them up the first time...)

Regards, Stefan.

Nice design!

I want to see a spin down time with and without the output coil on the board.

Nice job Romero.  ;]
A light bulb should be easy. It doesnt have to be 100w to prove anything. Small 4w consumes 30ma at 120v.  It should light bright and they are cheap.  Then step up as you develop it.

Hey Romero

That rotor gets up to good speeds with that single stator. Have you measured the input current to see power in?  Be interesting.

From what I see, if you add more gen coils, they could all join to a single cap. You may see some drag by adding say 3 more, but then you can readjust.  Myself, I would have each of the 4 coils with their own reed and out diode, all to 1 cap, and stagger the coils so they fire in sequence. ;]   I think you are getting very good power out for the distance from the rotor. 

The core, is it just some of the original core but short?

I like the heavy rotor and the mags worked out perfect.  =]
