Thank the following friends help:

    @ neptune
    @ wattsup
    @ chrisC
    I follow the suggestion to experiment, In the "A" "B" short position, But still can not get the rotor acceleration.
    Where I did not do right?
    Should be adjusted where?

    I rotor speed is 1500rpm,
    Each generating coil resistance is 2 ohms,
    Generation coil and the rotor magnet gap 8mm.

Try this:

For now remove the large cap
Start the rotor with a load( light bulb)
Let it run at max speed.
Then , with the light bulb conected , put it in dead short
You should hear the rotor speeding up a bit and the current droping a bit ( that's how it works for me)

@baroutologos
Seems like you understand how it should happen and it is not happening. Others just do as they are told and get the speedup ? There must be something you are missing.
On the other hand your goal is not the speedup but to be able to steal some kind of "state" in a way to not bother the rest of the device. For example charge a cap or copy the potential difference on the varicap. Did you try this ?
You also mentioned that coil shorting gives benefits. What happened to that project ? What is the limitation of the shorting because it is not good enough to be used ?

@mariuscivic
Nice. Since you get the boost when having 1 coil or when you short all coils. Can you try to short the coils 1 by 1 without treating them as 1 ?

"-why did romero used small magnets for triggering one pair of coils?"
i think that was a temporary solution, later he used the big magnets. The smaller the magnet the smaller interval you can leave the hall trigger working. Maybe he needed bigger itnervals

"-why his rotor has less acceleration with nothing connected to the output?"
if I is lagging after induction, that might create a time gap between the rotor inducing in 1 way then in other way. There might be an interval when the coil instead of oposing the magnet movement it is trying to help it. If you try to calculate the amount of time this happen you will get to a quite small number.

"-why his current is always the same when accelerating and reaching max speed?"
This speedup is not what you are seeking, you wish to convert this speedup to output and not loose the extra gain as mechanical loss. If you would be able to maintain the speed then you could raise your I or V


The question still remains. Are you able to scale this speedup effect ? Can you put a second coil that will further increase speed ? Please note that nobody said that second coil needs to copy first coil. Maybe it needs to be closer to rotor.

Could it be considered an optimization that when magnet aproaches coil to lag I behind then at peak output position to force it to lag in front of V ? ( when V sine wave is increasing you lag I behind and when V starts to decrease you force I to lag in front of V ). If this can be improved and I is causing lenz drag then you can eliminate or reduce Lenz considerably or totaly.
If you can lag I behind V with a capacitor and you can force I to get in front of V with a resistance. You could use a switch to reroute your output from a capacitor to your load after sine peak.

will this new speed be better then without having the generator coil at all ?

@all,

A couple of things of interest -

I can generate over 200v DC from the output by using a series cap, 0.47uf, with the 21 watt bulb (about 1 ohm) and quickly shorting across the cap. Do not use the buffer cap - many uf, high volts.

Its weird to note where this voltage is stored and eventually drains down. I can tell you that it packs
a punch.

Has anyone else noticed the generating capablities of the "DRIVE" circuit. Simply connect a voltmeter
across the input wires to drive circuit without power and rotate rotor by hand.
