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

No the contacts will burn at 3A without capacitors due to the inductive load. Its just a matter of time before this happens.

Yes, but they are quite cheap relays, maybe a few of them had worse conduction and burned. I have one strip from another manufacturer and only 2/8 are good!
There was never more than 10A for ALL.

PC's frequency is correct.  However there is so much more room for improvement.  Wire size and turns will play a big deal moving forward.  It will slap you in the face, once you get it.  It is hidden for sure, and understand why PC has discovered a very important effect.  He has given all the answers in his videos.  Constantly ask yourself questions that relate to a true generator.  If you don't understand true generator basics.  Then you will not get his device.  His very uniquely hidden concept is in every single generator.  Again, which type of A/C generator does PC's device most closely resemble?  Then study it's components and cycles.  Ask yourslef what is your device missing that a normal generator always has.  When you find the answer...it will hit you hard and you'll see that PC is not hidding any truth in his words and videos.

I have no problem in understanding the two basic types of AC generator.The stator distributed windings and wound rotor are similar to a synchronous alternator in reverse, except the stator winding is
energised instead of the rotor.
The big difference is the energisation of whole sections of  the DZ stator windings, whereas the alternator only energises the rotor (DC) which sweeps across the stator windings. For a two pole rotor, every 180 degrees there is a flux polarity reversal. In the case of the DZ generator there are 6 polarity reversals in 360 degrees.
Both generators use distributed windings to approximate a sinewave, although on a 30 slot stator a 3 phase alternator only has to accommodate 3 groups of windings so there is a gap between coils which produces more of a sine rather than a triangular wave.

So Jerdee, why are you so cryptic in your posts, I thought this is supposed to be an open forum?

Is there field self excitation? Some feedback from the armature back into the stator windings? Has this been either confirmed or denied?

Just looking at the relay specs,it may be false economy to replace these.
The 10,000 operation life would easily be exceeded in a couple of hours running.

This is one of reasons to replace them with solid state MOSFETs... https://i.imgur.com/fmLCUGR.png
Or just make like Figuera with simple disk and contacts on it.

Cheers!

@ L192 and all

Pierre told me that some time ago most of the relays on his device caught on fire. The stator is fine but all the rest is fried.
So even if he would of been opened to having someone go for a live demo he had nothing to show. Lucky for us he made the videos before the fire.
So you are right, those who chose relays will only have a certain amount of time before your relays contacts fail and weld shut and possibly catch fire.
Pierre decided to rebuild with improvements but that will take take him months. Meanwhile we are free to use what he shared and from our tests we can try to find the missing ingredient.
Jerdee lives very close to me and we've been working together as a team. He does the programming and research (think tank) and I build and test.
Working together we think we may of found something but I have to rebuild using the 40 Amp Dual Half Bridge to test if it works as Jerdee thinks it will.
So nothing is certain but for sure there are clues to be found which Jerdee has spent weeks researching.

We will give an update when we can but we also have to respect Pierre's wishes which is to protect him and his discovery from theft. So we should not publicly share until we know Pierre has protection in place which I will know when it is and notify the group. After that, Pierre or any of us (who have figured it out) can publicly share.

I hope you and everyone else building Pierre's device understand and respect his wishes.

Kind regards
Luc

Fr. @ L192 et tout
Pierre m'a dit qu'il y a quelque temps la plupart des relais de son appareil ont pris feu. Le stator va bien mais tout le reste est frit.
Donc, même s'il voulait invité à faire une démonstration en direct, il n'avait rien à montrer. Heureusement pour nous, il a fait les vidéos avant le feu.
Vous avez raison, ceux qui ont choisi les relais n'auront qu'un certain temps avant que les contacts tombent en panne ou qu'il soudre et prenne feu.
Pierre a décidé de reconstruire avec des améliorations mais cela prendra des mois. En attendant, nous sommes libres d'utiliser ce qu'il a partagé et de nos tests, nous pouvons essayer de trouver l'ingrédient manquant.
Jerdee vit très près de moi et nous avons travaillé ensemble en équipe. Il fait de la programmation et de la recherche (think tank) et je construis et test.
En travaillant ensemble, nous pensons avoir trouver quelque chose, mais je dois reconstruire en utilisant le Dual Half Bridge de 40 Amp pour tester si cela fonctionne comme Jerdee le pense.
Donc, rien n'est certain, mais il est certain que Jerdee a passé des semaines à chercher des indices.
Nous donnerons une mise à jour quand nous le pourrons mais nous devons aussi respecter les souhaits de Pierre qui est de le protéger et de le protéger contre le vol. Donc, nous ne devrions pas partager publiquement jusqu'à ce que nous sachions que Pierre a mis en place une protection que je saurai quand et aviser le groupe. Après cela, Pierre ou l'un d'entre nous (qui l'a compris) peut partager publiquement.
J'espère que vous et tous ceux qui construisent l'appareil de Pierre comprennent et respectent ses désirs.
Sincères amitiés

I opened one and found just by using some solvent spray I was able to restore contact resistance in the milliohm range. It may be possible to drill a small hole (without removing relay from the board) to inject some solvent.

My two relays I used for polarity reversal did get very hot, as they were carrying the whole load. To actually catch fire, I think more than 10A would have to be applied. So much for the theory that 3.5 to 5A is enough.
