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

Konehead,

The way Pierre had his poles/coils configured and biased is as follows:

6 poles each consisting of 6 coils in series. All poles in series (so 36 coils in series together with coil 36 connecting back to coil 1).

He put +Vdd on coil 1, 13, 25 and GND on coil 7, 19, 31. So this effectively puts each pole N/S (consisting of 6 coils in series) in parrallel with the other poles.

This leads to the 6 poles N S N S N S (or nnnnnn ssssss nnnnnn ssssss nnnnnn ssssss) where capital N/S represents a pole and small n/s are the individual coils)

Pierre montre le champ magnétique avec de la limaiile de fer.
Je me demande pourquoi les particules de poudre de fer tournent à la fois sur elle-mêmes (à la vitesse de commutation des relais: quelques hertz) et très lentement autour du stator en plusieurs dizaines de secondes.
Il semblerait qu'il y a 2 champs très différents !
Pouvez-vous expliquer ce comportement ?

Pierre shows the magnetic field with iron limaiile.
I wonder why the particles of iron powder turn both on themselves (at the switching speed of the relays: a few hertz) and very slowly around the stator in several tens of seconds.
It seems that there are 2 very different fields!
Can you explain this behavior?

Well my thought is the waveform switching speed is only 16ms however,  waveform amplitude varies from 0 to 100% at 60Hz.

Pour moi, cela n'explique pas le déplacement lent des particules autour du stator.

For me it doesn't explain the slow particles displacement around the stator.
