He put that tiny "Mo-Gen-Flywheel apparatus" on Y.T. to pretend look like a moron. That's because of security reasons to avoid the government secret guys when he releases the REAL THING.

"He put that tiny "Mo-Gen-Flywheel apparatus" on Y.T. to pretend look like a moron. That's because of security reasons to avoid the government secret guys when he releases the REAL THING." he certainly succeeded; maybe looks are not deceptive and he actually looks like what he is, just like  Gerard Morin.

Yes, that is correct regarding having two coils on at the same time. But look at his blue LEDs: there are always two on next to each other. But total only 6 are on (3 sets of 2 LEDs spaced at 8-10-12 "off LEDs" as mentioned before), so he is switching 6 coils total (not 12) per step. E.g. he will switch the 6 coils in slots 1-2, 11-12, 23-24, then it shifts to slots 2-3, 12-13, 24-25, etc. on the next step.

I have verified that this will generate the six poles NSNSNS that Pierre mentions. I am going to write this up in a PDF with clear images once I have some more time.

Hi PmgR,

Seaad posted in another forum "I have toggled the film frame by frame and found that it is always between 6 -12 relay LEDs lit simultaneously"

It may be the overlap is only 1ms, so easily missed that 12 coils are on at the same time?

Stator re-winding update: https://youtu.be/Yp8FFPQ2E7M

Hi Luc,

Before you start on winding, I have a quick update on the simulations.

I am not sure what winding span Pierre is using but if it is 6, it doesn't produce a nice even field around the stator (see that attached image Config010).

For a 36 slot stator, the ideal configuration for 6 poles happens when each coil spans 7 slots, so wire in slot 1 (let's saying going up) and return wire going down into slot 7 (wire going down), the next windings will go:

01-07 08-14 15-21 22-28 29-35 36-06
07-13 14-20 21-27 28-34 35-05 06-12
13-19 20-26 27-33 34-04 05-11 12-18
19-25 26-32 33-03 04-10 11-17 18-24
25-31 32-02 03-09 10-16 17-23 24-30
31-01 02-08 09-05 16-22 23-29 30-36

So you start at slot 1 and end at slot 36 and exactly 6x6=36 windings.

Please see the attached to image (Config012). I removed the output coil for clarity in these simulations.

Please double check with Pierre if he has his coils covered 6 slots or 7. If he is only covering 6 slots, his field won't be perfect going around 360deg along the stator.

Applying the same logic to your stator, to get an even field, you would need each coil to span 6 slots, so this would mean the following for your stator:
01-06 07-12 13-18 19-24 25-30
01-06 07-12 13-18 19-24 25-30
01-06 07-12 13-18 19-24 25-30
01-06 07-12 13-18 19-24 25-30
01-06 07-12 13-18 19-24 25-30

You see the problem with this: you would be filling up the same slot going around. So there is a problem with trying to get this done on this 30 slot stator. Looks like 36 slots is a magic number. 

I tried a 5 slot coil span and a 7 span coil span as well, but they have a similar problem:

5 slot coil span:
01-05 06-10 11-15 16-20 21-25 26-30
01-05 06-10 11-15 16-20 21-25 26-30
etc.

7 slot coil span:
01-07 08-14 15-21 22-28 29-05
06-12 13-19 20-26 27-03
04-10 11-17 18-24 25-02
03-09 10-16 17-23 24-30

So this is not going to work either. You would only end up with only 17 coils before the same slot starts refilling.

Last try: 10 slot coil span:
01-10 11-20 21-30
01-10 11-20 21-30

Same problem here, so I give up. I don't think you can get a nice 6 poles field with 30 slots.

Magic number appears to be 36 (=3*3*4, 4*9, 3*6)

Maybe it is better to get a 36 poles stator instead of trying to spend your time winding this one.

Last note:

To my humble opinion, when two or more coils are overlapping, meaning that they have a common core area, then the transformer effect takes place. That means if both of the coils (which actually act as two primaries)are pushing a North to the same direction, then the induced currents between each other will reduce the flow of the current from the source (battery or caps bank) to both of the coils. The outcome will be a North of a much lower intensity than when one coil is in action.

Jeg, you are correct, take one more look at my images. For Config010, two neighboring slots have current running in the same direction, Config012 has current running in opposite direction. Config010 makes a much better poled field towards the center of the stator. Config012 appears to be creating another pole in between the two wire slots.

Why guys are you're always aiming towards a BIG contraption? I'm always searching for "the OU effect" and that can be done with small units.
