Heheh hopefully your jimboot was successful! So u mean secondary gen coils?

Yes sir, just a wild idea

since we are inducting the primaries why not use secondaries to get some transfered energies from the near primaries?

Well im successfully charging an old flat 9v duracell. More watts in than out i'd say but I'm not sure how to do the measurement. I'm using a 12vdc sla @ 200ma charging a cap to 7v and hanging the 9v off that. running at 7200rpm. The gen coil slows the rotor marginally. I have it attached to a rectifier schottky bridge . Im not shorting out the coil. That simply stops the rotor. Would it be poss to have the charge coil dump freq match that of the pulse coil? I was thinking of taking a parrallel trigger from my hall switch to dump the charge coil.

Here is the scope shot. The green trace is the pu coil which charges a cap quickly now to 10v. Not sure if the p2p voltage is of any significance or not.

Hi Jimboot,

If you divide the peak to peak voltage value, 20.31 by 2.82, you get about 7.2V AC RMS and after the full wave rectification the capacitor is charged to the single peak value of this RMS which is 7.2V times 1.41, i.e. 10.15V DC what you can measure.  Now the measured numbers are ok because the induced voltage is sinusoidal.
