The variation of the magnet field is nothing more than the production of pure sine by changing for each field coil. It is the variability of the magnet and it is 60Hz.

Is there anything else?

Maybe the direction of the "flux-lines" ??

In a mechanical generator, you have momentum and twisting of the magnetic fields (opposed fields are generated, armature reaction) This is not increments or steps in momentum, armature reaction, and field intensity.  These parameters do not like to be incremented/decremented. 

To simulate momentum, you use overlap in the code to never break the fields rotation.  Again, its not perfect, there is room for improvement here.  I don't see PWM on each stator coil as the answer, you do not want to shut off the field in rotation.  Hold it as it goes around.  The answer lies in the wire.  If you change the wire as it rotates, and change it in a VERY dramatic way as it rotates (stronger the intensity), you will have something.

I have also shown in my post why the code is not the same through loop.  It is not a glitch. When you learn variation, intensity, and momentum of the magnetic field through the wire only, the code now has purpose.

All while this is going on, the opposed generated field from the intensity is always reflected back and captured. You now see why 72 diodes were used instead of 36.  I believe there is a better way.  I'm not sure on best method moving forward at the moment, but active rectification on coil pairs makes sense to me, at least at this moment.

Remember that the load as generating its own opposed fields for more recovery.

Can anyone of you recommend a proper method for ACTIVE A/C rectification?  When coil is North, you recover differently than when coil is in south.  The stronger your simulated magnetic field, and load, the stronger your recovery needs to be as well.   There are new chips on the market for active rectification, but something tells me there is a simpler method.  So if anyone has experience in this area.  It would be nice to see help.

Dans un générateur mécanique, vous avez un momentum et une torsion des champs magnétiques (des champs opposés sont générés, une réaction d'induit) Ce ne sont pas des incréments ou des pas dans l'impulsion, la réaction d'induit et l'intensité du champ. Ces paramètres n'aiment pas être incrémentés / décrémentés.

Pour simuler l'élan, vous utilisez le chevauchement dans le code pour ne jamais casser la rotation des champs. Encore une fois, ce n'est pas parfait, il y a place à amélioration ici. Je ne vois pas PWM sur chaque bobine de stator comme la réponse, vous ne voulez pas fermer le champ en rotation. Tenez-le comme il va autour. La réponse réside dans le fil. Si vous changez le fil pendant qu'il tourne, et le changez d'une manière TRÈS dramatique pendant qu'il tourne (plus fort l'intensité), vous aurez quelque chose.

J'ai également montré dans mon post pourquoi le code n'est pas le même à travers la boucle. Ce n'est pas un problème. Lorsque vous apprenez la variation, l'intensité et l'élan du champ magnétique à travers le fil seulement, le code a maintenant un but.

Pendant tout ce temps, le champ généré opposé de l'intensité est toujours réfléchi et capturé. Vous voyez maintenant pourquoi 72 diodes ont été utilisées au lieu de 36. Je crois qu'il y a un meilleur moyen. Je ne suis pas sûr de la meilleure méthode pour l'instant, mais la rectification active sur les paires de bobines est logique pour moi, du moins en ce moment.

Rappelez-vous que la charge génère ses propres champs opposés pour plus de récupération.

Quelqu'un d'entre vous peut-il recommander une méthode appropriée pour la rectification ACTIVE A / C? Lorsque la bobine est au nord, vous récupérez différemment que lorsque la bobine est au sud. Plus votre champ magnétique simulé et votre charge sont forts, plus votre récupération doit être forte. Il y a de nouvelles puces sur le marché pour la rectification active, mais quelque chose me dit qu'il existe une méthode plus simple. Donc, si quelqu'un a de l'expérience dans ce domaine. Ce serait bien de voir de l'aide.

I posted an applet some time back showing a vector animation of how the very same in achieved in an induction motor.
I would suggest the switches move the waveform every 20ms (50Hz) 16ms (60Hz) and PWM is applied to a series MOSFET supply the DC rail. The PWM should produce a half sine and is synced to the start of the 20ms period. This will provide amplitude variation of the wave form (sine) from 0V to DC rail max. Every 20ms the whole waveform moves on. The relays or MOSFET switches would only be swiching at a low rate. The PWM is filtered to produce an unbroken half sine. Therefore a pulsating and traveling wave is produced. Not the missing pistons but the missing piston rings.

Nice thought.  Maybe? 
How would you recover the field with your idea?  The DC rail is your recovery, wouldn't that affect your filtering?  How would you keep voltage constant?
There is room for improvement for sure.

You can control the power of the H bridge through PWM. Do you have other reasons ?

No I think are several methods to accomplish this. You may be able to use the bridge enable lines .I was thinking of a single switch between the cap bank and the boards. The supply caps on each board acting as a filter with external diodes recovering to the cap bank. Needs some thought.
Isolate the switch with diode to ensure no recovery back through the MOSFET body diode.
