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

Hello Luc,

did I miss something ; can you explain to me how is ordered the closing of the contact (green arrow) which allows the passage of the negative current?
Thank you

Bonjour Luc,

j'ai loupé quelque chose ; pouvez-vous m'expliquer comment est commandée la fermeture du contact (flèche verte) qui permet le passage du courant négatif ?
Merci

I made 2 videos, the first one in English and the next in French.
These videos are to explain the coils firring sequence and what I believe to be the reason why there's next to no flux going through the center core coil.

Fr. J'ai fait 2 vidéos, la première en anglais et la suivante en français.
Cette vidéo a pour but d'expliquer la séquence d'allumage des bobines et ce que je crois être la raison pour laquelle il n'y a pas de flux passant par la bobine du noyau central.

Hi Gotoluc,

Actually it was 5 coils not a single coil and when I added the next coil group (5 coils) opposite polarity  the output dropped due to the partial cancellation of the MMF.

I was going to conduct a single coil test but now I know what is happening I don't need to do that.

Luc,

The way you showed your sequence in the latest video to me is totally wrong.
I think it should be ,5 coils putting out a north, at the same time 180 degrees away 5 coils putting out a south, and then progress the fields one slot at a time.
You have 3 fields n,s,n....n,s,n??  I'm not sure if this is what you have ,but if it is this would explain the low output.

Hi L192
When you say "one slot as a gap" between poles, do you mean that the slot should be completely blank/empty? Or this slot contains the last coil of the previous pole and the first coil of the next pole? Is that possible for a winding graphic representation of your idea?

Luc, is there any chance for a mistake when you were connecting your coils between each other? Out of the "no-current at all" result, looks like that you accidentally have connected them as cw+ccw+cw+ccw...etc. Can you verify this easily? Or else you can fire them one by one and check the polarity with a compass.
