Shorting coil gives back more power

[hartiberlin]

with R he probably means graetz bridge rectifier and the + and - output
are the DC outputs of the bridge rectifier.

Now it gets clearer.

He also uses greatz bridge rectifiers in his video.

What is R on schematic ?

Does not really needed,just put an oil capacitor AC there and it should be much better.

The circuit on the videos is little different from this one.Only common is the theory.Here it is.

 hi Stephan

Thank's for your shematic

I made a crude replication tonight with the air core coil of the primary of a mot and a 12 volts relay "modified to self trigering)

The frequencys is arround 400 hz (at 9 volts input ) and i get some results but so far not extraordinary..

But i will try deeper in the  concept tomorrow

Anyway thanks for the input

And good luck at all

By the way i am trying a new setup now with no moving relays and mechanical stuff.Hope to finish it soon.

    Just a tidbit here. With the magnets positioned the way they
are, when they go by the coils it will do a hard pole reversal. This
will create a sine wave output as if you had spaced north/south
magnets. You will not get as strong a field to the coils that way
but switching poles.
