Thanks very much Konehead

for all your info and very apreciated knowledge transfer very helpfull

Hi Clanzer

do not worry for those probably too much sensitive post from people who have not taken the time to  simply study your magnifique design. But there is a lot like this  in this forum and   sometimes it is disturbing to say the less.

OK for today

I am probably beginning a very serious hard job here,

So as i sayd, i wound my 18 coils with 0.3 mm plain copper wire. So i got about 450 turns per coils with an average DC resistance of 5.5 ohms.

So for the new commer , i have 7 sets of 2 coils wounded in serie (that is to say about 11 ohms DC resistance per set ), for generation of  the output power.

Those  7 sets are powered by 2 sets of coils ,wounded in serie and powered by the ROMERO's circuit as described in the Stephan PDF.

The trigger magnet are positionned near the center of the rotor, (not at the periphery ) see pix

I tried 3 different size of stator magnets in attracting and repelling position ( as per rotor magnet)  All cores  on both (upper and bottom stator) were covered by those biasing magnets

The best result , concerning  the stator magnets above the generative coils, is for me and my setup without any doubt  , in REPELLING position to the rotor magnet is far the best , I know i am very surprised by this result but as i sayd , this machine has to be understood as a whole  and not as an addition of separated parts. My 2 cents.

The powering cores and coils are not biased at all by stator magnet,


I could get from  no stator magnet up to the best config ( 20 mm diameter  by 10 mm thikness disc N42 magnet) SO FAR , from 15 volt  to 27 volts.(open circuit)

This means that the Stator magnets are really important.

In the pix annexed, you see that i could get 27 volts with an input  of around 12 volts for about 118 ma.

But no chance to loop at the present.

Another thing , i measured the DC / DC converter and at 12 volt input and set to 12 volts output,it draws 52 ma.  = 0.6 watt ouch !!


So first result

input    11.7 volts at 117 ma   produce   on a single set of coil arrounf 24 volts at 1225 RPM (open circuit )

input    11.7 volts at 117 ma produce, on all parrallel connected 7 sets of coils ,arround 26 volts at 1225 RPM ( open circuit )


A lot of work is remaining for me to get what Romero got.

good luck at all

My pushes in the right direction seems to have gone unnoticed.

If you would like to know where the engineering I speak of comes from:

The guys I have worked with over the years spent 8 hours or more a day doing what you are doing with one exception; a huge budget.

I laugh when I hear "It wont work! Because if it COULD work, it would already have been built!"

Yes.  That is correct..Except for the first part.

Zero Power consumption is not allowed in industry.

But 10 watts for a typical hundred watt pump(or more) is allowed. {wink, wink}

My pushes in the right direction seems to have gone unnoticed.

If the COP is 10, efficiency is somewhat moot. If COP is 1.1 it is of paramount importance.

You are pushing for improvements in efficiency, and well you should. I think that most folks here are still in a mode of trying to prove that COP > 1 is possible, and once that is proven, efficiency starts to matter a great deal more. If you want to get everyone's attention, offer an experiment that demonstrates COP > 1...you'll have their undivided attention.

Gyula and konehead - Thank you once again!  All great info and thanks gyula for so much info on the diodes.  I'm still reading all the links.  I ordered a boat load of Schottky's but at a small cost so I'll probably try my plan with them and if they won't cut it I'll try what Romero used.  Other than paralleling the 1N4001's onto his bridge rectifiers I don't recall ever seeing what exact bridge rectifier he was using.  They looked small so maybe 2A @ 100 volt or somewhere in that range.

Laurent, do you plan to experiment with litz wire too, at one point ? (It's still unclear to me if Romero used it or not on the self looping video, he said so at least).

Anyways, congrats for the job and information sharing so far
