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

[MichelM]

Hi L192,

I attach it again. But this time it is a video file (.mp4). I hope this will work as it looks like only the first frame of the animated gif went through. The .mp4 file size is only a fraction of the animated gif file size. Put on repeat mode in the video viewer to see it loop like the original gif-file.

Hello Ole,

good animation. This is the theoretical rotation of magnetic fields as I thought them too. But since the last indications that Pierre has communicated to us, I am not so sure that this is the case. Even if the reels actually seem to be ordered to move the fields such as in the animation, I think we have to think about how he arranged the reels. Notice: the last 6 reels are placed on the top layer; when these six coils are powered simultaneously, I think this produces a field that covers 11 stator grooves, not 6 grooves. I indicate it on the two images below. If this is the case, then magnetic fields are much more unbalanced than the theoretical fields. What do you think ?

Bonjour Ole,

bonne animation. Ceci est la rotation théorique des champs magnétiques tels que je les pensais moi aussi. Mais depuis les dernières indications que Pierre nous a communiquées, je ne suis pas aussi certain que cela se passe ainsi. Même si les bobines semblent effectivement être commandées pour déplacer les champs tels que dans l'animation, je pense qu'il faut réfléchir à la façon dont il a agencé les bobines. Remarquez : les 6 dernières bobines sont placées sur la couche supérieure ; lorsque ces six bobines sont alimentées simultanément, je pense que cela produit un champ qui couvre 11 rainures du stator, et non 6 rainures. Je l'indique sur les deux images ci-dessous. Si tel est le cas, alors on a des champs magnétiques beaucoup plus déséquilibrés qu'avec les champs théoriques. Qu'en pensez-vous ?

Please note about 5 coils in "11 slot" spot winding wire direction is CCW on top of the rest of coils wire direction which are CW. In that spot the EMF cancellation is in full effect.
Then compare to Luc and L192 replications winding. You will see instant difference.

Cheers!

Sorry MichelM, but your conclusion is incorrect.  The coils are producing a field that is 5 coils wide, not 11.  I have reattached your drawing.  If you look at the wires on the right side of the coil, they are coming towards you or maybe going away from you.  But the wires on the left side of the coils are going in the OPPOSITE direction.  That means that if the wires on the right are producing a north field then the wires on the left are producing a south field.  I have built motors  using that same principle where I had a north magnet over one set of wires and the south magnet over the other set of wires and it ran just fine.

Sorry citfta, but your conclusion is incorrect.  The coils are producing a field that is probably  narrower than 5 coils wide. See my pic above.

Sorry citfta, but your conclusion is incorrect.  The coils are producing a field that is probably  narrower than 5 coils wide. See my pic above. 

If all coils are same around stator as those 5 overlapping and the end of each coil ends on +5th position from begining then you have  very narrow space between North and South poles when making 2 poles with 1 coil spacing from each to the next. And this still makes N/S vector in the direction of the ring and not to towards center. This is not what you want in Pierre's replication...
