Pierre's 170W in 1600W out Looped Very impressive Build continued & moderated

Sorry citfta, but your conclusion is incorrect.  The coils are producing a field that is probably  narrower than 5 coils wide. See my pic above. 

Hi seaad,

I share your opinion. If only these narrow fields act (the rest must still act), the current configuration of the winding of Luc does not have dominant magnetic fields, since its coils cover 6 grooves and are grouped in series of 5 coils. In his case, the 2 windings of all the grooves have fields in opposition. This is perhaps why his rotor is so weakly magnetized.
What I explained above and that I show on this image again, comes in addition and must be taken into consideration. In the configuration of Pierre, any series of 6 coils covers 11 grooves, it's a fact, but what I want to share is the observation that I made: such as Pierre wound his stator, the last 6 coils that he has placed not only cover 11 grooves, but they, and only these last 6 coils, cover the coils already in place in the grooves. This must necessarily change the magnetism of these 6 coils. And when, during the rotation of the fields, when these 6 coils are connected in series, their magnetic field must necessarily be different from the others, since in their 11 grooves, the same magnetic field is directed towards the center of the stator. This concerns about 1/3 of the circumference and not 1/6.

Salut seaad,

je partage votre avis. Si seuls ces champs étroits agissent (le reste doit quand même agir), la configuration actuelle du bobinage de Luc ne possède pas de champs magnétiques dominants, puisque ses bobines couvrent 6 rainures et sont regroupées en séries de 5 bobines. Dans son cas, les 2 bobinages de toutes les rainures présentent des champs en opposition. C'est peut-être pour cela que sont rotor est si faiblement magnétisé.
Ce que j'ai expliqué ci-dessus et que je montre sur cette image à nouveau, vient en complément et doit être pris en considération. Dans la configuration de Pierre, n'importe quelle série de 6 bobines couvre 11 rainures, c'est un fait, mais ce que je souhaite partager, c'est la constatation que j'ai faite : tel que Pierre a bobiné son stator, les 6 dernières bobines qu'il a placées, non seulement couvrent 11 rainures, mais elles, et uniquement ces 6 dernières bobines, recouvrent les bobines déjà en place dans les rainures. Cela doit forcément modifier la magnétisme de ces 6 bobines. Et lorsqu'au cours de la rotation des champs, lorsque ces 6 bobines se trouvent connectées en série, leur champ magnétique doit forcément être différent des autres, puisque dans leurs 11 rainures, le même champ magnétique est dirigé vers le centre du stator. Cela concerne environ 1/3 de la circonférence et non 1/6.

As Pierre explained, he hand wound the coils thats why they appear as they do. All of the coils polarities are the same in the series connection. Only the current direction is changing the poles North or South.

Pierre explained it! listener192 confirms

@ T1000,
I think all of Pierre's coils are wound CW, see mine they are all CW but look a little messed up where I ended.
I'm putting my rotating field on the inside and just using stock windings for the generating coils.

Doesn't that make a discontinuity in the waveform?

I apologize, you are correct!  I stand corrected.

We will have to do twice the amount of control on H-Bridges.
Each line of switching in the code is HIGH BUT, 1 pin is for three positive polarity, and another pin HIGH for three negative polarities.  Just need to make sure we can trigger three H-bridges from one high pin and use extra pins to switch polarity on the H-bridges.

Please see attached PDF to help the understanding.

All thirty H-bridges are firing for each half of the code.  Twice per code loop, each in opposite polarity.
By doing this, you have three North fields in parallel and three South's in parallel with the DC source at any one point in time.
BTW...this lines up with Ole's animation and Pierre's original code.

Hope this helps, and apologize for this confusion.  Please let me know if this looks incorrect.
