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

Looks robust enough. I am curious to read your review on this.

Why are you using separate arduino output pins for driving the below switches while they can be driven by sharing the same input with their mate switch at the above row?

Hi Jeg,

Yes I could do that, I just decided to keep full independent control for experimentation purposes.

Hi Everyone
Pierre just put his videos back up again on youtube parts 1 through 4
He has comments section open too but did not see him answer any questions there (yet)
Seems like he wants to stay being open sourced....
Ask him questions there!

Personally I think 6 individual N-S stator-poles at 60 degrees  are energized and then sequentially pulsed in rotation, and continued around flipping polariies every single "pole-segment" - so if 36 poles, this is every revolution 36 polarity changes and because so many polarity changes, this is where the big power is produced....also this is done with that overlapping sequence as Pierre outlined in his circuit  drawing...
Now why is it so overunity is the very interesting and unique winding pattern, which puts backemf and lenz law forces to work reinforcing the power produced, not cancelling it...
I will guess really not much "flyback" energy is produced from the diodes and the reason for the all the recovery diodes is just to protect the electronics more than anything...(could be wrong and this is lots and lots of energy recovered into cap banks - interesting experiment for Pierre would be to put this into 2nd cap bank see if it still loops just as long in time (forever)
Anyways this all my opininons nothing else, working looping models on bench would make it fact...

Big Question:
Were those "magic numbers" Pierre released a few weeks ago correct or was he mistaken??
Seems like now 1-7 etc etc is correct now looking at drawings and lots of analysis , not 1-6 as he put out...maybe this is for slots instead poles I don't know...

Hi Konehead,

See attached.

As area A (red) moves into registration with rotor, coil inductance increases rotor induction happens current flows in load and a counter flux is set up in the rotor and stator. The counterflux sees the high reluctance path offered by the stator path to the rotor however the counter flux sees a lower reluctance path (green) offered by the adjacent pole where the energizing  flux is in the same direction.

At this point this adjacent area is not in registration with the rotor, so induction is low and little counter flux is generated to oppose area A counter flux. It would have to be modeled to confirm this.

Hi Jeg,


I just checked and it 0.53mm which is 23AWG rated at about 5A continuous at a nominal temperature. The wire is is rated to 160 deg C, so it could be run beyond 5A.

I had plenty of this gauge and also 0.8mm which is closer to 20AWG.

The slot CSA would accommodate 0.8mm however it would be tight getting the wire pass the pole ends.

L192, what is the resistance and inductance of one of your coils by itself (no rotor present).

Hi PmgR,

Mine are all connected in series in  the loom, heat shrunk and tie wrapped, so it will be tomorrow before I can find an open place to break the loop.

I may have a spare coil which I can measure the resistance.

L192, you can measure from one half of the stator to the other half of the stator. I believe you have 30slots, so you would be measuring two parallel strings of 15 inductors in series, so what you would measure would be 7.5*L and 7.5*R where R and L are for a single coil. So no need to disconnect anything. Just make sure the rotor is not in the stator.
