Try winding the coils in normal but back to back out of phase. Then try bifilar connections.   Even  multifilar with diode plugs on the ends. I don't know what works best and Romero want everyone to do their own research.

HV electrostatic charges can make another proxy without using cores. Im sure there are other ways too.

Great work. Are you shorting one coil or all coils at once?

Hi there

I'm shorting the output wich means all the coils

[mariuscivic]

Are you shorting the coils at points A and B continuously or in pulses as Kone has been describing? Also, I just want to confirm that according to your drawing, your generator coils are wired in a bucking (canceling) configuration?

Thank you,

Hi there

I'm not shorting in A or B. I'm shorting the output after the bridge rectifier. That was just an observation while playing with the device.
The coils are in the bucking configuration but the curent is not canceling becouse  betwin the coils we have N and S from the magnet

I experimented with the dual coil in series and shorted them with an 1 ohm resistor, when second coil is in right place I get acceleration. Maybe other people who want to experiment can use this setup because it is very simple, just an old cd case and a pc fan.

LOL Thanks! I've been working on it for a while now  .

Anyway, I've spent some time reading through your posts over the last week or so and wanted to come up with a summary of the basic principles we need to start with.

1. Tune our coils to have the most reactive energy stored in the tank circuit/coil (VARS).

yes

A. PF needs to be 0 with the current 90 degrees out of phase in the tank (hence resonance).

yes

B. Large inductance, low capacitance preferred.

yes


C. Either non-inductive bifilar coil or two bucking coils needed to energize the tank circuit without loading the motor.

or a mixture of the two.

2. Use one of several methods to tap the energy from the tank circuit (coil shorting, synchronous load switching, passive tuning, sine clipping using Zeners, etc. etc.).

can be passive but active power factor correction is easier to deal with dynamic and variable loads.

Since I'm still stuck at stage 1. One thing I know I immediately failed to do was to wire my coils in the bucking configuration while tuning to resonance. Bolt, when you say "Out of phase coils back to back", I understand the "back to back" part to mean that the coils are wired so that their fields oppose. However is the "out of phase" part something additional that I need to cause by my configuration or does this effect naturally occur on its own because coils are bucking eachother?

back to back for opposing fields and maybe even bifilar wound cores crossed over like joule thief windings. This is why Romero said stay with ONE pair of coils and don't go any further till you have found the perfect solution.

Secondly, when picking the right size cap for the coil in this configuration, I noticed that when measuring the inductance of the coils in bucking configuration that the inductance dropped (duh). However, I'm assuming that the circuit behavior is much more dynamic since the magnet is essentially (electrostatically inducing power??) in the coil rather than magnetically. Do you know if the same standard resonant frequency calcs apply to tuning the circuit in bucking/canceling mode as in the normal cases?

I don't know the formula for out of phase inductors. They will APPEAR to be very small inductors as the test equipment pushes an in phase signal and the new special inductor cancels the flux and it appears to be a small inductance. So you can not pre-measure and calc or measure  the required capacitor that would be too damn easy

Also, earlier when I mentioned metallic cores, I was just referring to any coil that had a ferromagnetic materials of some kind in it. My pulse motor has pure air cores which is why I was concerned about that aspect.

OK i doubt standard aircore go OU very easy if at all as there is no proxy for ambient energy transformation.

Hint for lower power drive on pulse motors use alike 50Khz PWM 61.8% duty cycle when the hall calls for a pulse during the allowed time slit window.

Hi Bolt,

Whew, thank you for this post.  How many times did you say the above......a lot, I'm old and stubborn and just didn't think the bucking coils resonated would work, stopped messing yesterday, had lots to try but just repeating old test, didn't feel good, so , just thought about it. You kept repeating yourself again and again, finally listened....Hard to teach old dogs new tricks. 

BUT.........IT WORKs.  Wheel runs faster with coils shorted, then in resonance, wheel runs even faster and does NOT slow down with load,  if tuned under load, even speeds up........  I'm going to have to rethink my whole idea about this!!!!!  IT simply unloads the system. 

Basics:  Series coils 26.7 ohms series resistance (wow High!, expensive Litz wire!  Too small) Bucking, screwy waveform as they are not exactly the same.  29mH with magnet, 25mH w/o magnet, 6.5VAC PP at resonance (and thinking in the box, it should be zero)!  A lot to get a handle on here. Arrrrrrrrrrrrrrrr.

Going to rewind coils to get resistance down, etc.  Lots to do now....essentially starting over!

Photo below is output @ resonance, clean sine wave.  Onward and upward.
