170 watts in - 1600 watts out - looped - Very impressive build and video

reducing ON duty cycle to both north and south poles as they approach and leave the rotor, would mitigate the problem without introducing pole gaps.

francais
réduire le cycle de service ON aux pôles nord et sud à mesure qu'ils s'approchent et quittent le rotor, atténuerait le problème sans introduire d'interstices entre les pôles

I also agree but what if this is what causes the positive results?

francais
Je suis également d'accord, mais il est possible que ce soit ce qui provoque les résultats positifs?

Hi Gotoluc,

Well Pierre is talking about separating the poles by two slots, what if that kills the effect?

My view is that if pierre's modification works and produces a cleaner waveform (albeit closer to a triangular step), without loosing the effect, then all well and good.

If not stick with the current scheme and rectify the output to DC and feed a pure sine static inverter.

Depending on the static inverter input say 24VDC model, just use less turns, heavier gauge wire on the rotor. 

Then concentrate on maximizing the input/output ratio.

I don't think you will get a good sine wave output, without applying a sine distribution to the poles.

The other area of experimentation would be to try a cylindrical rotor.

Did you miss the part about the rotating magnetic field?
You could start by considering the nearly 250 watts (allegedly) dissipated in the big power resistor. And continue on to consider the massive eddy current losses in the motionless "rotor" and stator cores.

I think I probably have a better idea about "how the input is working" than some others here may have.

Nope did not miss that part when drawing it and writing out the sequence of events that make sense of it from beginning to end.

Nor did I miss the part where Peirre showed the temp of the resistor and radiator, which is part of the "minus losses" that are very real considerations.

I don't doubt that you do have ideas, and so do the others and myself as well. If I thought otherwise you wouldn't be reading this or anything else from me about your "ability to comprehend it" and my willingness to personally try to show you what you admit you don't understand. Don't get me wrong: I don't claim to know it all or what Peirre actually has going on - but I do know some of what hasn't been discussed here to date.

Two heads can be better than one. - But I know better than to put seven engineers to work designing a Horse: because they'll come up with a Camel every time.

As always: it is up to you.

Message from Pierre

Hello to all,
I see some have trouble understanding how the dz generator works. I will help by showing you step by step by building a second prototype.
I managed to find a new 10hp 3 phase motor, so it's going to be a bigger prototype than my first version.
I'm keeping my fingers crossed that I'll be able to build a second functional version that will work right from the start and also solve the problems of the first prototype.
All your constructive comment will be welcome and I would like to thank those who have already given some good advice.
Please be patient because my biggest problem is the lack of free time. I'll only have a few hours on weekends to work on this new prototype, so it's not going to go very quickly but step by step I'll get it done. 

Thanks for everyone support.

Pierre

bonjour a tous !comme je voie vous avez du mal a comprendre comment le dz générateur fonctionne je vais vous aidez en vous montrant pas a pas la fabrication de mon deuxième prototype et oui j'ai réussi a trouver un nouveau moteur de 10hp  3ph cette fois ci et donc plus gros que ma première version j'espère pouvoir régler les problèmes du premier prototype pour pouvoir faire une deuxième version fonctionelle je me croise les doigts pour que tout fonctionne du premier coup   tout vos commentaire constructif seront la bienvenue merci déjà a ceux qui mon déjà conseiller il ne vous reste qu'a rester patient car mon plus gros problème est le manque de temps je n'ai que quelque heures les fin de semaine pour travailler sur le prototype alors je n'avance pas vite  pas a pas je vais finir par y arriver merci a tout le monde . pierre!

Jeg, didn't you watch the video I linked above?

You use a cold chisel to cut off the coil wires on _one side only_, flush with the metal of the stator core. Then from the _other side_ where intact loops still exist, you pull the wires out using the loops, while heating the core from inside if necessary to free things up.

The video also shows how the "winding" is done: windings are prepared off the core in "skeins", then are carefully inserted into the core slots.

If i had seen it it wouldn't take me a whole day to clean the core! But the worst is that now my core looks quite small!!
