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

[seaad]

Just a repetition from my post in energeticforum:
I come to think of this when I reed Pierres last letter.
Part of the Figuera patent.

A)
(pat.1908) " circulates a proper current, which is taken from one foreign
origin into one or more electromagnets, magnetize one or more
electromagnets"

" and while the current is higher or lower the magnetization of
the electromagnets ((one or more)) is decreasing or increasing and varying"

decreasing or increasing and varying

B)
(pat.1914) " but in no case is there any communication between the induced coil
and the inductor coil "

C)
(pat.1914) " and we will collect from these induced ((y)) the resulting
phenomena experienced from those inductors. ((N, S)) "

Hi,
FR/
variation du flux magnétique ?
je pense qu'il y'a déjà une variation du flux du au fait de cour circuiter 1/5 bobine soit 20%. c'est peut être pas suffisant et qu'il
faudrait simplement en courcircuiter  2 à 3 bobine à la fois ca va permettre une augmentation du courant dans les autres bobines
qu'en penser vous ?

ENvariation of the magnetic flux? I think there is already a variation in the flow of the fact of running circuit 1/5 coil or 20%. it may not be enough and we should simply short  2 to 3 coil at a time it will allow an increase in the current in the other coils
what do you think?

Oui, Mosha, c'est un très bon point et un moyen possible qui doit être pris en considération.
De plus, le programme original de Pierre qu'il m'a envoyé contenait un petit problème qui a été corrigé par PmgR et peut-être d'autres. Cependant, nous devrions considérer cela comme un indice possible et non comme une erreur de la part de Pierre.
Merci d'avoir porté cela à notre attention.
Nous avons beaucoup de bons esprits ici et en travaillant ensemble, nous serons en mesure de résoudre chaque problème au fur et à mesure.

Eng. Yes, Mosha, that is very good point and a possible way which needs consideration.
Also, Pierre's original program he sent me contained a glitch of some kind which was corrected by PmgR and maybe others. However, we should be looking at this as a possible hint and not an error on Pierre's part.
Thank you for bringing this to our attention.
We have a lot of good minds here and by working together we will be able to solve each issue as they come.

The easiest way to vary the current through all of the coils is with PWM.

We are generating a travelling wave via the rotating poles lets say at 10Hz, then via PWM we superimpose 60Hz on top of the 10Hz wave?

The other way around. We have to build a low frequency with the help of a high frequency switching. The sketch needs a variable to be set so to increase the "on" time of the pulse, coil after coil and then back again to 50% for a full cycle. It is easy i guess but first lets solve the overlapping problem. Looks like Pierre's new topology solves this issue and still keeps the uniformity all around the stator.

Another very important variation we need to consider when using Solid State vs Relay switching is, we know Pierre is pushing his relays to their mechanical limits and he has said many times he would like to even go to higher frequencies but the relays can't handle it.
So the reality is, when pushing a relay to its mechanical limit you get to a point that even though you program tells the relay to stay on for x amount of time, it actually does much less. So when using solid state components which does not suffer from this issue (time reduction) we need to consider this.  So we should have the ability to reduce duty cycle (on time) and overlap time to tune the device's input power and overall efficiency.

Fr.  Une autre variation très importante que nous devons prendre en compte lors de l'utilisation de la commutation Solid State vs Relay est que nous savons que Pierre pousse ses relais à leurs limites mécaniques et il aimerait même aller à des fréquences plus élevées mais les relais ne peuvent pas le gérer.
Donc, en réalité, lorsque vous augmentez un relais à sa limite mécanique, vous arrivez à un point où, même si vous programmez le relais pour qu'il reste allumé pendant x temps, il en fait beaucoup moins. Donc, lorsque vous utilisez des composants à l'état solide qui ne souffre pas de ce problème (réductiont de temps), alors nous devons considérer cela et devrions avoir la possibilité de réduire le cycle de service (à temps) et le temps de chevauchement pour régler la puissance d'entrée de l'appareil et l'efficacité globale

Indeed, Luc, upload the potentiometer sketch to the Arduino and put the rotary magnet back in, start at a low frequency, get the magnet spinning and then turn up the frequency to see what happens.
