Thanks Pierre,

I know you are busy.  Just processing research that is very interesting and seams to follows your work, at least at the moment it is very similar.

The method shown allows ONE out of the THREE phases OFF at any one point in time.  Each OFF position rotates through all phases.  This is the coils RETURN.  Or the inductive kick back. 

The stator has TWO opposite polarity phases at once,  while one phase is off.  TWO powered phases is better than ONE.  This generates a much stronger magnetic field and transfer of flux to the armature.

Still learning.

Merci Pierre,

Je sais que tu es occupé. Il suffit de traiter la recherche qui est très intéressante et qui suit votre travail, du moins pour le moment, c'est très similaire.

La méthode montrée permet à l'UN des TROIS phases d'être OFF à n'importe quel moment. Chaque position OFF tourne à travers toutes les phases. C'est le retour des bobines. Ou le coup de retour inductif.

Le stator a DEUX phases de polarité opposées à la fois, tandis qu'une phase est OFF. Deux phases ON valent mieux qu'une. Ceci génère un champ magnétique beaucoup plus fort et un transfert du flux aux rotor.

Encore à apprendre.

Bonsoir jerdee! Oui ils serait mieux d'avoir un triphasere sauf que le lien que vous avez envoyer parle d'un moteur avec un aimant rotatif bien sûr que vous pouvez faire du courant comme cela sauf que mon principe est inverse c'est le champ du stator qui tourne le fait que j'ai mit 6 champ tournant était simplement pour avoir une fréquence plus élevée parceque les relais ne m'aurait pas donner une fréquence assez élevée en mettant 6 champ tournant j'ai multiplier par 3 la fréquence des relais avoir eu des mosfet comme Luc j'aurait pue me permettre seulement 2 pole et j'aurait pue avoir facilement la fréquence désirée et des résultats probablement supérieur à ce que j'ai obtenue car le champ aurait été 3 fois plus fort que 6 champ

En.  Good evening jerdee!  Yes. it would be better to have a tri-phase, except the link you posted is about a motor with a rotating magnet. Of course you can make the current like that, except my principle is the reverse. It's the field of the stator that rotate. The 6 rotating fields was just to have a higher frequency because the relays would not give me a high enough frequency. By having 6 rotating fields it multiplies the relay frequency by 3.  If I would of had some mosfet's like Luc I could of used only 2 poles and could of easily had the desired frequency and probably better results than I obtained because the field would have been 3 times stronger then 6 fields.

Finally got back to the starting point. New bridge boards all working. 5 coil 30slot stator.

25V into super cap bank from current limited switched mode DC supply. Bridge boards connected to this rail via 16A circuit breaker.

Adjusted clock for largest output, using the pot control method.

230V 100W bulb used as load.

60uF cap cleans up and maximizes output waveform.
Rotor covers 6 slots and has original generator 2 x 115V windings (in series)

Well done L192. Back to testing again. In case you will need sync with mains... http://www.emergingtechs.org/p/zer.html

I should also mention that a test using coils 1-16 (2 poles) resulted in an asymmetric waveform , with less output than the 6 pole arrangement.
This configuration did produce a very large rotational torque which required extra wedging measures to stop the rotor from turning.  You would think the A/Turns developed should have resulted in very large induction.

As a random thought, I am wondering if the expected flux reversals are instead flux level variations. Time to put the flux probe in the stator -rotor air gap and confirm what is actually happening.See  attached.
Flux appears to bi-polar, as center line on the scope is zero flux.
