Hi Luc
From the drawing Pierre did of how he switches his coils, and the description he gave, it seems the coils are connected in series, but they are not pulsed together in a series connection (hope that makes sense I think it does).....but to confuse more, there is a "series" sequential rotation to them (one after the other with overlapping time period too)  words are hard to make things clear sometimes!
Intertwined or interlaced both similar words ..... but what I think he is trying to say (maybe) is the coils are all connected together (in series) but not pulsed in series....just as that diagram shows he drew....
I am sure if I stuck that the French you just posted into translator program it will just make it more confusing you do a very great job with translating....

Thanks konehead
I think it would be even more confusing to use a google translation of Pierre's French text. Give it a try

hello, yes your sequence seems correct every pair of numbers that I gave you is a coil that intertwines all connect in series I would like to put more coil if I had more slot of the stator because I wanted to make a graph in the form of stairs and more steps would have been small between each pulse it could have made a nice curve like a magnet passing in front of a coil to make the current (see photo 1) left standard alternating current wave and right curve that I wanted to get but as you know my system does not work as I want it yes it seems to work at first glance but in part only the curve I wanted only works on some portion (see photos 2) and I got several peaks very high and a lot of Fluctuation is what is due to my craft winding, relays that does not open at the right time a few milliseconds can make the difference, the induction of a reel to another ?? or a stroke of luck myself I was surprised at the result, actually for the moment I do not know I'm trying to understand what I made all I know is that I got a can of voltage .but not usable if I can not understand the principle of the generator dz for the moment I try to solve this problem, for which of the 6 poles I use 6 nsnsns but maybe 2 -3-4 poles could have worked I do not know I did not test I started to study the magnetic field phenomenon there is a little less than a year and I am far from an expert a this subject for the moment there is a lot of work to arrive at something viable and functional and with my work I do not have much time in a week to do experiments. as for the sequence of the arduino when you will do the sequence you will have to turn on one coil and then the other and eventually turn off the first one otherwise you will cut the magnetic field the goal being not to turn off the stream only move it ex: 1 on, 2 on, 1 off, 3 on, 2 off etc. for which of the diodes back it was installed directly on the reels but there are probably ways to do it more simply I wanted to manage the power with another arduino but I was eager to test my device and finally I connect it directly without control it would have reduced the consumption to enter the how much I do not know, I do not know if you noticed but the supercapacitor was designed to rise up to 48 volts and I only 26volts injected but saw the problem meet I liked better wait for the next prototype, do not hesitate to take the initiative if you can improve things made it the generator dz is still developing there are probably something that my escape but has several we will eventually find the solution thank you.
for who's pictures I'm not able to send them to you he talks about moderator and anyway I think my photos are too heavy

I use 6 poles, nsnsns but maybe a 2, 3 or 4 poles could worked? I don't know, as I haven't built or tested it.
The firring sequence konehead has shared seems correct. Every pair of numbers that I gave him is a coil which intertwines and are all connected in series.
I would of liked to add more coils if the stator had more slot, because I would of liked a wave in the form of stairs so the steps would be smaller between each pulse, which could of produced a nicer curve like a magnet passing a coil which makes current wave as pic 1 (left) and (right) is a standard step alternating current curve which I would of liked but my generator is not yet ideal.
At first glance it seems to work but with only a portion of the curve I wanted to produce (pic 2)
The peaks have a lot of Fluctuations, some are higher then others.
Possibly some relays don't open at the exact time. Just a few milliseconds can make a difference. Maybe variation in induction from one coil to another plays part?  probably my winding skills are to blame?  it's a stroke of luck to get it all right.
I was surprised of the result. Still I don't yet fully understand what I built.
All I know is that I was able to get some extra voltage. However, it's not useful if I don't understand the generators principle! At this time I'm trying to solve this problem.
A little less then a year ago I started to study magnetic field phenomenons but I'm far from being an expert on the subject. There's still a lot to improve to achieve something functional and reliable.
As you know, my work takes most of my time during the week, so I don't have much time left to experiment.
About the sequence of the arduino, when one coil is powered on the next coil will also be powered on before the previous is turned off (overlap) otherwise you will break the magnetic field. The goal is not to turn off the magnetic stream, you only want to keep it moving.  Switching example: 1 on, 2 on, 1 off, 3 on, 2 off etc.
The flyback diodes are connected to each coil but there's probably simple ways to do it?
I wanted to regulate the input power with another arduino but I was too eager to test my device so I directly connected it without input control. Maybe I could of reduced the input power but how much I do not know.
I don't know if you noticed the super capacitors can handle up to 48 volts. I only used 26volts but because of the problems I encountered.  I prefer to wait to test higher voltage on the next prototype.
Don't hesitate to take the initiative if you can improve the dz generator. It's still in developing stage and there's probably many things I haven't thought of that can be improved.
If we work together we will eventually find the ideal solution.

bonjour ,oui votre séquence semble correct chaque paire de chiffre que je vous ai donner est une bobine qui s'entrelasse tous relier en série  j'aurait aimer mettre plus de bobine si j'aurait eu plus de fente du stator car je voulait faire un graphique en forme d'escalier et plus les pas aurait été petit entre chaque pulsation  cela aurait pu faire une belle courbe comme une aimant passant devant une bobine pour faire du courant (voir photo 1) a gauche onde courant alternatif standard et a droit la courbe que je voulait obtenir  mais comme vous le savez mon system ne fonctionne pas encore comme je le veut oui ca semble fonctionner a première vue mais en partie seulement la courbe que je désirait  fonctionne seulement sur quelque portion ( voir photos 2) et j'ai obtenue plusieurs  pointe très haute et beaucoup de Fluctuation est ce que c'est du a mon bobinage artisanal ,les relais qui ne s'ouvre pas au bon moment quelque milliseconde peuvent  faire la différence  ,l'induction d'une bobine a l'autre ?? ou bien un coup de chance moi même j'ai été surpris du résultat , en fait pour le moment j'en sait rien je tente de comprendre  ce que j'ai fabriquer tout ce que je sait c'est que j'ai obtenue un peut de voltage .mais inutilisable si je n'arrive pas a comprendre le principe du dz générateur pour le moment je tente de régler  ce problème, pour de qui est des 6 pôles moi j'en ai utiliser 6 nsnsns mais peut-être que 2-3-4 pôles aurait pu fonctionner je ne sait pas je ne l'ai pas tester j'ai commencé a étudier le phénomènes des champ magnétique il y a un peut moins d'un an et je suis loin d'être un spécialiste a ce sujet pour le moment   il y a beaucoup de travail  pour en arriver a quelque chose de viable  et fonctionelle et avec mon travail il ne me reste pas beaucoup de temps dans une semaine a faire des expérimentations . pour de ce qui est de la séquence de l'arduino quand vous ferez la séquence vous devrez allumer une bobine et puis l'autre  et par la suite éteindre la première  sinon vous allez coupé le champ magnétique le but étant de ne pas éteindre le flux seulement le déplacer    ex:1 on, 2 on, 1 off ,3 on, 2 off etc. pour de qui est des diodes de retour il on été  installé  directement sur les bobines mais ils y a probablement des façon de le faire plus simplement je voulait gèrer l'alimentation avec un autre arduino mais j'avait hâte de tester mon appareil et finalement je l'ai brancher directement sans control cela aurait permis de diminuer la consommation a l'entrer de combien je ne sait pas ,je ne sait pas si vous l'avez remarquer mais les supercapaciteur on été conçue pour monté jusqu'a 48 volts et je ne lui est injecter que 26volts  mais vus les problème rencontrer j'aimais mieux attendre au prochain prototype , n'hésiter pas a prendre l'initiative si vous pouvez améliorer des choses faite-le le dz générateur est encore en développement  il y a surement des chose qui mon échapper mais a plusieurs on finiras par trouver la solution merci.
pour de qui est des photos je suis pas capable de vous les faire parvenir  il me parle  de modérateur et de toute façon je croit que mes photos sont trop lourde

Now here is another aspect..coil current.

The DC rail under load appears to drop to around 21V. The unloaded rail is about 25V.

The AC power into the transformer is about 113V x 1.6A or about 180W with the microwave oven load (note I think that meter has a 100A range so that current reading could be +/- 0.1A according to the specs).

Now about 11W of the 180W is the transformer magnetizing current based on the 115V flickering 0.1A no load readings.

Lets take that 180W as a worst case, so 180W/21V= 8.57A average  .. 8.57A/12 coils on at any time (assuming overlapping on periods) = 0.71A average per coil.

So those L298N H bridges should be OK as they are rated at 2A continuous per output.  (you can also parallel them to get up to 3.5A)

We have not seen a scope waveform of a coil current pulse yet but I think that would be interesting to see.

The clock period for obtaining 60Hz is 100ms. The ON period could exceed 100ms running into the next coil period before turning OFF for coil recovery.

Regarding the stepped sine approximation. I would ask Pierre just to try a suitably rated poly cap of about 50 to 60uf in parallel with the fixed rotor coil. That or an adjusted value will clean up the steps into a sine wave however, I would be cautious that this does not cause the setup to drop out of OU, as this cap would also effect the CEMF phase.

Another way would be another large value inductor in series with the fixed rotor output. That will add some IR losses though.

Another thought is use H bridges and run the whole setup at a higher frequency, but lower voltage say 24V, rectify the output and feed a pure sine static inverter to obtain the voltage and frequency desired.

The inductance of the coils is not consistent through rotation, so some current pulses will be higher than others, also relay contacts may be sparking. The use of H bridges would clean this up.

A 4 pole fixed rotor would help mitigate the current amplitude variation.

A cylindrical rotor would provide a uniform air gap and maintain a constant coil inductance however, this may also alter the OU condition.
