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

[d3x0r]

Possibly the ending of previous coil are too tight with beginning of new coil on each pin? If that is a case it is getting cancellation. It have to be at least few centimeters distance between coils. And it is main reason why I am still looking for hard-to-get stator which would allow fill space with core between those ends.
In that video each pin around a ring have individual formed magnet with opposite to the next pin I guess?
Also all coils need to be in same direction. But the current flow need to be opposite on every 6 coils from 36 around stator.

P.S> We need to generate moving field to be same as we would turn rotor with 3 phase magnets inside of stator. Not just rotating magnetic field around coil axis.

The original pairing given by Pierre was 1-6.  That's a skip of 5 for a paired winding.  the first coils on are 1 and 13, which puts a skip of 2 between the second and third windings, but then its pair had a skip of 0.

I added black dashes later to separate the N and S (or S and N ) paired coils... which then puts 3 sets of close poles with gaps
as illustrated here

But because of the series driving piere's coils can't actually be driven like that so you need a span of a couple on .... which then you lose the sparation; and although Pierre never showed 4 poles, one might extrapolate that you'd have a pair close, a skip, and another pair close.

Those images do not reflect actual required magnetic polarities. When position 1,13,24 are +HIGH with the position 5,17,29 are +LOW. And position 7,19,30 -LOW with position 11,23,34 -HIGH ('-' = inverted current direction representation). That assumes all coils are on same direction and in series. Then we have same polarity over 4 coils towards center and opposite polarity outside of stator.

P.S> To test polarities set delay for 30 seconds and to limit current have bulb attached in series to coils.

The capacitors were the expensive part found these

2.7V 500F on a CDSWELL charge balancer
https://amzn.to/2FzaEXb
apparently pierre's capacitors are only 1/2 charged since he has 3 of these in series.  They're also sold as car voltage boosters; they come with a 50W resistor because a DC battery can dump so much current probably. 

Arduino mega is cheap of course; and relays...
opto isolated
https://amzn.to/2Ibf8bZ

there was only one of these
https://amzn.to/2KvS2ej
but it's also optoisolated and claims 5mA operation... thought the other was the same but I guess no.

And after a little research; even though these are also low-enable, writing output to a high before setting it as an output will first-enable with the pin high; https://www.selloutsoon.com/albums/documents/20-018-102/8+Relay+Module.rar has a internal schematic.  Without a logic input enabled to pull it down, the relays won't enable on initial power up.

You have a bad connect on the lower left switch.
Also, you have 4 relays between the coils on the end (two to the left of the first, and two to the right of last) not 100% why that's causing the oscillation, since it should be just the same as having the first closed; which it already is...

Any advice where to source AC motor/generator cores?  Was considering getting a alternator from the junk yard, but they don't have very much metal on the outside for the outer flux path.
