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

Hi Konehead,

Does Pierre mean 3 poles pairs (6 poles) or 6 pole pairs (twelve poles)?

Hi L92
He says six rotating fields in video, then said 6 poles 3 N 3S alternating in magic numbers reply, so must be six poles however he says that there is "overlap" in the "series" coils timing and so you could almost say it is 12 since that overlap "between" almost could be counted as double the number....
Looks like he connects the stator coils in series too such as all one long string of them all the way around then there is a sequence one on, both on, next one on.... however not sure about this - but his circuit drawing shows something like this going on...

Hi Konehead,

If you wire all the norths in series and all the souths in series then you only need 12 switches, so you would have to wind 2 more coil sets over 2 more rotations to use all 36 switches.

It makes no sense to me, why you would repeat the same scheme just with a slot offset?

Also the stator looks like it has only has 2 wire bundles per slot?

Each coil must have a reasonable number of turns to achieve viable flux linkage.

Just to be clear. The coils are not powered in Series. They may look in series looking at the schematic he made but the switch (relay) keeps the coils separate.

I chose the word intertwined but a more direct translation wold be interlaced (EN) from the word entrelasse (FR) if that helps? the below is Pierre French text.

oui votre séquence semble correct chaque paire de chiffre que je vous ai donner est une bobine qui s'entrelasse tous relier en série

Let me know it that helps

Hi Gotoluc,

Ok that makes sense.

Intertwined probably just means lapped, in this case 2 wire bundles in each slot.

The number of turns of each coil would be useful information, as well as wire gauge (looks like 20AWG or 0.8mm)
