Hi all

Looks now like the AC yellow cap is in paralell with the DC cap seen from top, and also there is a diode there too, in the RomeroUK drive circuit...

to fill up a DC cap with the backemf/recoil of coil,  NPN mosfet or transistor, you have the single diode come off the SOURCE lead of mosfet (not the DRAIN) and then you have common connection of other lead (pos) of cap and the coil lead that connects to positive of battery-supply...

for PNP jsut flip all this around (common grounds then and source-lead is positive)

this fills up cap NON REFLECTIVE for sure, unles syou dump into too-big of cap...

I like to SWTICH the backemf into cap...not jsut let the diode work "all the time" but have the circuit connect only during the time the recoil and backemf occur during the turn-off period of the motor coil.....so what you do is put 2nd swtich on the backemf circuit (which is jsut a diode and DC cap!)
put this switch on coil-leg, or on cap doestn matter that much just make it so it disconnects the coil somehow from the cap....

if using a fWBR to capture the backemf, then on one of the AC legs is nice place to put this 2nd "backemf" switch.
Now time this swtihc to have same pulsewidth as motor coil switching, but delay it about 5 degrees retarded to motor coil swtich....find sweet spot and motor will go down in draw and up in speed when large-size cap fills up - you have to experiment with cap size....sometimes load right over cap is good thing...also you can skip teh caps altotherter and run on 24VDC from two batteris in seires and dump DC side of FWBR into 12V battery stack "direct" this is very fun to do - find sweet spot and motor races up in speed when DC side of FWBR hits battery load (sometimes)...going off subject here but its something related...

I think maybe Romero has his two motor circuits (that are out of phase) connected in the manner that the "steering diode" off the source-lead of one mosfet/transistor
fills up the DC cap in the "other" motor/drive circuti and vice versa so the backemf has somewhere to go that is "external" to the motor/drive circuit that the backemf is taken out of in first place...normally you fill up DC cap, then pulse cap to load when coil is disconnected from cap so that the event of hittling load doesnt lug anything.
but with that other "out of phase" motor coils circuit, the DC cap in there is ideal to pop the backemf into.....
anyways more theory on what he did....maybe he ALSO strings all those generator ocils together, and blasts the backefm THROUGH THEM all at once, on its "way" or "from"  that DC cap in the other motor coil circuit??? theres another idea/experimet to try  too...

all that I wrote about the the AC cap inseries a few posts back is whole other subject - I dont htink Formereo did this, if he says hsi AC cap is in paraell with the DC one.

Hi everyone!

Just want to throw in an ideea.
We know that a permanent connected load is giving the coil lenz.
What if we connect the load only in the top of the sinewave? ( for a short period of time). Connecting a load only at the peak of the sinewave should give us lenz too BUT for a very short period of time  lenz will not affect the rotor speed  becouse the magnet will be in TDC.
Now, the magnet moves from left to right.
When connecting the load only at TDC , the magnet should be pushed or attracted up or down not left or right (depending by the polarity of the magnet)

I came up with this ideea watching the small magnets on romero's rotor.
I also put on my rotor small mags to trigger another sensor from another driving circuit. I replaced the battery with the output of a gen coil. And where should be the driving coil i put a load. Using the scope i could trigger the circuit at the peak of the sinewave . The problem is that the sensor is ON too long and this gave me lenz again.

Please tell me what you think about this and of course... why shouldn't work

Hi Marisuvic

If you think about it, a capacitor is not going to fill up a speck more in voltage than whatever that peak in voltage is at the peak of the sinewave - so WHY leave the cap connected to the diodes and coil during the time the sinewave dips after the peak??

Only reason is to get more LENZ LUG happening if you want a gernator that works as a brake to the axle it spins on....

the other reason, is this is how most engineers were taught  to test power from a generator since they dont want to fool with capacitor discharge formulas; (put a resistor right across the coil or phase and measure power they will say..."lump resistive load")

But its the FILLING OF CAPS that is the concern and objective of generator coils really - how fast and how high can it be done with largest cap possible....

Having a cap across the load at same time it is tested with the lump resistive load will help output a bit,  but thats not how to do it - the way to do it is:
fill caps, dump caps to load and have caps disconnected from coils when they do hit load...(two stage output)

If you do take out power at the sinewave peaks-only, which is good idea for sure, while "you are there" at the sinewave peak, you might as well SHORT that coil at that peak-period....now you will get HUGE power into the caps....just dont have resistance across the caps when they fill...do that in "2nd stage" where cap disconnects from coils when cap hits load....

one thing nice about the sinewave peak no matter what is being done, is it a "no-mans land" sort of thing to the rotor magnets...the magnet doesnt care which way to move; forwards or backwards when a coil is energized at just the peak-only period....sort of a teeter-totter point...so lenz law has no jursidiction there....

Hi konehead

Thank you for the time spent by explaining this once again. I'm trying every method that cames into my mind but for now all i get is lenz.
Taking power(or shorting) only at the peak of the sinewave should be working but we need some serious electronics here. From what i saw , we need to control the time period that the sensor will be ON. The faster the rotor spins, the shorter will be the sensor ON.

@mariuscivic

I have been following silently for a while now since I have been  busy on some other projects. In the above video, can you please try something because you have the perfect set-up to see any differences.

Let's say in your drive coil case, the transistor is switching the negative side of the power supply to make the drive connect and turn. That is the pulsed feed side (PF) of the drive coil. On the other side of the drive coil is the permanently connected (PC) side that has no switching with wire going to the positive of the feed supply. So you have a circuit that could be summed up as follows;

positive ---- PC ----- Drive coil ----- PF ----- negative

What I would like you to try is to add a second coil in series with the drive coil but without that new coil being used to turn the wheel. Just leave it near the drive coil. The new set-up would look as follows.

positive ---- added coil ----  PC ----- Drive coil ----- PF ----- negative

So the added coil is on the side of the drive coil that never pulses.

Please try this and maybe find other coils to replace this new one to see the difference and if you can for yourself see the effect it has on your wheel, the heat from the drive coil, increase/decrease of power consumption, etc.

-----------------------------------------------

About the idea of bleeding the generator coils at peak, this has been tried so many times by others. The fact remains that the gen coil still has to produce the peak you want to cut so there is no hiding from Lenz there. I had discussed about this somewhere else but cannot remember where to point you.

But in a nutshell, let's say the gencoil goes from 0 - 10 (peak) in 1 second, so you want to take out the peak, you will open a transistor for a fraction of that second when it is at peak. This does nothing to save Lenz. But what you can do is this. Do not let the gen coil reach the peak. Instead when the gen coil goes from 0-5, you take the 5 and the gen coil falls to 0 again then goes back up to 5 again that you take again, and so on. So instead of taking the peak at every one second, you take two halves twice per second into two individual caps, then parallel them or series them as you want to discharge. Whatever you decide to do with the caps will not effect the gen coil because from now on it would be going from 0-5 instead of 0-10 thus cutting the Lenz in  half while still producing the same (or near same) wattage equivalence. Just a thought. Maybe try to find a 12v and a 6v zenor diode that feed the light bulb and try each one to see the effects of bleeding the output at 12v or at 6v. If with the 6v, the bulb is half lit, then a small circuit to switch the 6v output into 2 channels that then discharge as one should do it. In terms of the formal circuit, that I cannot help with - sorry about that.
