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

Wow Luc, simply amazing the kind of craftmanship you put into this! Great videos!

Luc...
Could you please ask Pierre to publish his Arduino code sketch? I think our being able to examine and analyze the sketch would clear up a lot of uncertainty about how the stator is wound and electrically sequenced to produce the effect he demonstrates.

This is an Achilles heel:
SONGLE RELAY
http://www.circuitbasics.com/wp-content/uploads/2015/11/SRD-05VDC-SL-C-Datasheet.pdf

Max. ON/OFF Switching
Mechanically   300 operation/min
Electrically        30 operation/min

Life Expectancy
Mechanically   10^7    Min. (no load)
Electrically     10^5  operations. Min. (at rated coil voltage)

So I hope the finding of real OU Can be noted fast before the relays crashes

Thanks seaad for pointing this out. The relay lifespan and maximum actuation speed puts some real practical limits on this device. Perhaps these parameters have already been exceeded, in fact. How long can the device actually operate before relays begin to fail? These relays are intended for applications such as switching power on and off to television sets, where the actuation rate is actually very low and the total actuations may be only thousands of times before the whole TV is thrown away and replaced with a new product. To achieve a 60 Hz output from Pierre's device, using a bank of these relays...

Very nice job, thank you for taking the time to video the process.

Thanks Garry for the appreciation

Thanks PmgR for your appreciation as well

Luc ...
Pourriez-vous demander à Pierre de publier son croquis de code Arduino? Je pense que le fait d'être en mesure d'examiner et d'analyser le croquis éclaircirait beaucoup d'incertitude sur la façon dont le stator est enroulé et séquencé électriquement pour produire l'effet qu'il démontre.

That's been on top of my list but I didn't want to ask until I could show that I'm a serious builder, experimenter (not just a taker). I think Pierre may see that now.
Partzman has confirmed today that he received the Mega 2560R3 and 20 of the L298N H-bridge but he's still expecting more L298N ordered from Georgia, USA any day now.
So I asked him to wait to send till he receives mail tomorrow as I may need 30 H-Bridge to possibly get it to work in a similar configuration as Pierre's relays.
I will ask Pierre if he's ready to share the Arduino code sketch he wrote to operate his prototype relays so I can test my replication with it.

Cela a été au sommet de ma liste mais je ne voulais pas demander jusqu'à ce que je puisse montrer que je suis un constructeur, expérimentateur sérieux (pas seulement ici pour prendre).
Je pense que Pierre peut voir ça maintenant.
Partzman a confirmé aujourd'hui qu'il a reçu le Mega 2560R3 et 20 pont  L298N, mais il attend toujours pour plus de L298N commandée de la Géorgie, aux États-Unis n'importe de quel jour.
Je lui ai donc demandé d'attendre jusqu'à ce qu'il reçoive le courrier demain car il me faudrait peut-être 30 L298N pour ma réplique fonctionne dans une configuration similaire à celle des relais de Pierre.
Je vais demander a Pierre s'il est prêt à partager son croquis de code Arduino qu'il a écrit et utilisé sur son prototype afin de tester ma réplication.

Hmmm... I see DigiKey has the L298N for $43.65 for 10 units.... free energy certainly isn't cheap is it!   

And this application will certainly need a printed circuit board to mount and route 30 of these devices... which by the way only handle about 2 amps per channel and will probably require heatsinks.

Has the PCB been designed yet?


(OH... now I see the module board photo. Well at least that solves some of the problems...)
It's hard for me to believe that those inexpensive modules from China will have genuine L298N parts on them, since the whole module is quite a bit cheaper than a bare chip from DigiKey.
