Hi Mariu
OK thanks  - thats a very long piece of ferrite...also maybe magnet stuck on back end too is something to try if you havent done that already. 
try the Teflon plumbing tape you are going to like it...

Hi Khwartz

here is the simple coil-shorting circuit below for a rotor-magnet induced generator coil, this doesnot have the pulse-width adjust to it either to make it simple)  this is not a motor/coil drive circuit....I do not have an output-cirucit for the cap in this, 
but look at the 2nd drawing - this is a backemf/recoil circuit, (also without any pulse-width adjsut to make simple)  for a motor/drive coil  (NOT a coil-shorting cirucit)
and it shows a simple "two stage" output circuit for it to the right in the drawing...same sort of thing should be done with the coil-shorting circuit too - idea is to have capacitor after it fills, be disconnected from the coil when the cap hits load....jsut be sure one is disconnected when other connects and vice versa so cap discharge does not effect anything else in circuit and it is completley isolated....timing and duration are things adjsutable to particular loads and speeds cap sizes, power needed etc etc jsut make sure one part is ON when other is OFF is important thing in the two-stage output circuit...

Hi Kone! Thanks for your reply and help.
Great materials! I've get I think very clearly now that 2 stages you spoke about and its function: to not perturb the rest of the circuit while we discharge the cap in the load
Is that with the position of the hall or the little magnet that we set the pulse-width adjustment in pulsing motor? or it has others uses?

Hi Konehead!
I have deleted my latest post couse the cap accross the coil was missing. Now is there.
In my present circuit (just like the diagram) i have only 2 resistors: 10K and 100 ohm . Replacing the 10K with 100ohm i have gained more rpm, less current drain and much higher bemf.The cap accross the coil is one from a computer power source and has this written: 684j 250V; this must be 0.68uF.
In the video you can see that when i connect the positive wire to the diode, the curent drain goes up a bit just like the rpm.In this moment the returning charging current is blocked. Now, why is the rotor speeding up? first there is no lenz from those few mA that were going back into the battery and second, this little charge stayes in the AC cap and ''fights'' with the next impulse from the battery. Maybe i am totally wrong but this is how i see it.
When the rotor starts to spin with the AC cap already connected i can see the current drain oscillating 3-4 times up and down until its a constant drop

Now that i have acces to the layers of the coil i've been pumping current to the first 3 layers of the coil( around 0.4A/12V). The other 8 layers were behaving just like the secondary of a transforner. The bemf was so high that i could get a plasma arc around 3mm. But in the end,(since there is no insulation between the layers) the plasma began to discharge between the layers. It was interesting couse i could get 12V 5W light bulb lit about half brightnes with the usual less current drain from the battery. I can not do that any more couse i have no wire left to build another coil with insulation between the layers.

Today i have reduced the current drain to 15.5mA without any change in rpm. I've done this by connecting my big cap(47 000uF) in parralel with the battery. Adding other big caps in paralel tooked the current drain again to 16.5-17mA.(i'm fighting with mA again )

Hi Marius! Thanks for the news corrected schematic
A bit like you that you use external layers as secondary, i thought it could be useful to have extra winding layers around the coils to collect all the energy that could have around and see how it could be possible to inject it in the circuit until the furthers one from the axis collects no more significant power. You know like a Faraday cage that stop all the EM-RadioWaves, but the extra-surrounding coils, could collect in forms of electrical flux.
For now, you have no coil around your motor to feed a battery or caps or load, will you do that then? I would be surprised that you get more out-power even it the state of your motor than you use to turn it...

hi Khwartz
Is that with the position of the hall or the little magnet that we set the pulse-width adjustment in pulsing motor? or it has others uses?"
Not sure what you mean here - yes that is the position "in the circuit" where the hall effect goes...in an actual generator, or a motor, you would have some sort of spinning disc in synch with the motor's rotor, and have hall effects be adjsutable in their postion for best timing....adjusting the position, while the motor or generator is running is best way to go.
for pulse-width adjstument, then there are two halleffects, a mosfet (or bidirectional mosfet) connect to each...it is then not only the postion in rotational timing to adjust, but also there is the distamce between the two halleffects to adjust too, which would be the pulse width adjustment.

Hi Kone! thanks for reply
It was the actual position around the motor (or the other disc as you said).

Quotein an actual generator, or a motor, you would have some sort of spinning disc in synch with the motor's rotor, and have hall effects be adjsutable in their postion for best timing....adjusting the position, while the motor or generator is running is best way to go.

Ok I got it for one timing for motor-generator and having a second if pulse-width adjustment. Thanks! (I start to have the big smug I had in my mind about all this starting to clear! ).
