This applet shows the situation in a three phase induction motor.
http://www.nptel.ac.in/courses/IIT-MADRAS/Electrical_Machines_II/animation/sinwave3-9.htm
Its the traveling wave that drags the rotor around. If this were a 3 phase transformer i.e. a second set of windings, you would have induction due to the traveling wave and induction due to the pulsating wave (the three phase AC).
In the DZ there is a traveling wave but no pulsating component (unless you pulse each coil set  off and on).

L192

OK, so the DZ does have more in common with a generator than a motor. I still can't determine "which one (generator) fits his device" but I'm now thinking he means "fit" in terms of electrical characteristics, not mechanical.

"Piston"; presumably that refers to the transfer of force, the flux in this case. Perhaps the polarity is being manipulated more than is apparent.

Can anyone advise...
Is a winding on a transformer that is open the same as one that is in a complete circuit, except blocked by diodes?


To eliminate the mutual induction on other stator coils I was considering adding diodes to the ground side (or power side) that prevents current in the other coils...


like this Falstad sim kinda  (sorry it's kinda a tangled mess; substituted a tapped transformer and tied existing things to it...

Edit: Sorry didn't check it after pasting in wong mode... should have been condensed like that.

Yes, that is the way if you use mosfets. I think that there is no need for this extra diode when using igbt's but i have to recheck it.

Pierre,

I know this secret. I will keep it for myself until others know it or tell it.
One of the films is "visible" this secret. You need to know what to look for and what is missing.
I confirmed it the way you did it :) and now I understand your surprise successfully!

I wonder about the time of work, and probably you too. Maybe you already know it but it's unusual.

Thank You !
Hi r2fpl,
I assume if you know the secret, then you by now should be reproducing the same results on your setup.
Do you have a photo of your test results that show this, or a video?
Regards
L192

Right!  Yes it shakes during the first "field flash sequence".   / Arne
If you look Pierre uses a rectangular laminated stack and has applied a resin loaded with steel particles.
I guess he made a tight fitting cylindrical mould and then just poured in the resin.

r2fpl,


Totally agree that diode recovery is not enough.  It is only one part of the equation. However in a generator you have an amplifying effect and the diodes will recover more once amplified.   :) Again, study AC generator basics.  You’ll see what I’m writing about.   Just like what Pierre has stated, a rotational system will not give you OU, it’s like an engine without pistons. Thanks for pointing out the 1/2 of 48V.


@L192,


Yes, I totally agree once again.   The current limiting resistor has it’s role for charging the cap bank.  I understand this already.  I’m not easily convinced it has another role either.   The switched mode power supply with current limiting would help as well.  The current limiting resistor is wasted heat!


Jerdee
Jerdee,
The amplifying effect in a synchronous generator, is due to the rotor having a large number of turns with respect to the stator windings.
The flux developed is dependent on the amp turns, so a large flux can be developed with only a small DC current, which results in a large induction in the stator windings.
The DZ generator is running in reverse to a synchronous generator, so the only increase in voltage is due to the transformer action between stator  and rotor. Recovery through the diodes is proportional to the rate of change in flux, which in the case of the "always on" coils, is a relatively small change, which I have confirmed and posted current waveforms.

For there to be significant recovery energy, a large change in flux is required, so this must be happening, although in the code we have been given, the only such potential change is the end of the sequence when all coils are turned off. I say potential, as the single diode scheme only provides a current path for recovery, if a low side switch remains on. There is evidence of this also in the scope shot I provided however the pulses are very narrow and probably only occur at all , due to at least one of the low side switches being on for a short duration during the turn off of all the other high side switches.
There is likely another switching event, such as a polarity reversal that would result in significant recovery energy. You wont see this in the blue LED timing, it is probably in the relay wiring.

Now you are probably going to say the amplifying effect is the due to a series of six coils in series acting as a boost converter when the low side switch turns off. There is a problem with that ... the high side switches are linked to corresponding low side switches, so they both turn off together. Without the high side switch remaining on, the energy stored in the series coils cannot be recovered via the diode as there is no current path. You may say what about the next high side switch along, that will still be on. Yes, but so will its paired low side switch so still no release of stored coil energy. 

Now if there were a polarity reversal to the relay supply rails, this may work.

Stator coil inductance and hence energy storage will increase whilst in registration with the rotor,under no load. This inductance being reduced by counter current due to
load. If inductance is reduced then energy recovery is reduced.

As the system has demonstrated that it is load invariant, more current is automatically supplied. The system behaves, as if lenz is not directly acting on source.

It is not easy to repeat the first time because you have to adjust.
You must find the answer that you are missing in what you did. It is not easy to understand immediately. "Think straight and you will find". I agree with these words. It is a cliché but it is. Do not look for mA search A. The diodes have two functions I think that you already know. When the effect appears, they come to life. Everything will be the same.

It's hard to think about it with what you have on the table because there is too much going on there. Even I do not know how to do it right now. You need a lot of work to continue joining the whole.
I apologize for not showing you the video, but if I showed you, you would know what to do. Do not take offense at me.
It's good that you write about what you do. Maybe you will come by yourself and maybe someone will tell you more. Jardee says that maybe a few people already know. Possible. Certainly there are those who do not write and do.

If you do not find it yourself, Pierre has promised us that he will show and say how it works and how to do it. If more people would be interested in this, it would be stated.

Lenz, I do not think so.

I do not understand your attitude. Here is a forum to share, exchange ideas and finds, not to hide while hinting that you have understood something.
Pierre is silent to protect his invention, but you are not the author, you have nothing to lose by explaining your idea or showing your results.

fr: je ne comprends pas votre attitude. Ici c'est un forum pour partager,  échanger idées et trouvailles, pas pour cacher tout en laissant entendre que vous avez compris quelque chose.
Pierre se tait pour protéger son invention, mais vous vous n'êtes pas l'auteur, vous n'avez rien à perdre en expliquant votre idée ou en montrant vos résultats.

Sorry cheors but I've been in constant communications with Pierre and know how he wants to proceed. It's not a question of attitude or wanting to hide things. It's a question of protection and to follow a well though out plan.
I use to believe public domain sharing would protect everyone but the reality is not so. Yesterday Pierre sent me an email to thank me for my post asking the active experimenters to hold off on sharing all the ingredients needed for a working device until Pierre is ready to go public himself or tells us we can do so.

Regards
Luc

Fr. Désolé, mais je suis en communication constante avec Pierre et je sais comment il veut procéder.  Ce n'est pas une question d'attitude ou de vouloir cacher des choses.  C'est une question de protection et de suivre un bon plan.
J'ai cru que le partage du domaine public protégerait tout le monde, mais la réalité ne l'est pas. Hier, Pierre m'a envoyé un email pour me remercier de mon post demandant aux expérimentateurs actifs de ne pas partager tous les ingrédients nécessaires pour un appareil en état de marche jusqu'à ce que Pierre soit prêt à rendre public lui-même ou nous dit que nous pouvons partager.
Cordialement
Luc

We've both arrived at the same conclusion.....and I just found I have a 36 slot stator laying around.
