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

would the shared slots not just create a cancellation of the turns in the coil legs, one coil putting out a north the other a south?
Pierre said their both on at the same time or they overlap.
Since all of the slots are shared all the way around ,complete cancellation?
If he shares slots then he has to use 7 slots per coil, if he has coils one after the next he has to use six slots, which I would think would not cause the fields to cancel?
Very confusing.

Hi Shylo
Maybe its a typo, but its not "or" they overlap, they are supposed to overlap for some time so the frotating ield never "turns off"
I agree with you in what you are thinking; two coils sharing same slot through the stator will cancel if pulsed opposite polarity - maybe this is the idea however??  I don't know still confused but we will eventually figure it all out I am sure.

First thing is I am NOT saying this does or doesn't work.  That remains to be seen.  But I am having a problem understanding why the interaction between the stator and fixed rotor is any different than the action between the primary and secondary of any transformer.  What makes this any different?  The rotating magnet field is still just changing the flux going through the secondary just like any normal transformer.  And any normal transformer has an increase in current in the primary when the secondary is loaded.  So what makes the action of this device any different, if in fact it is real?

Hi Shylo,

Yes, a given slot at a pole change will have two coil sides with current opposing, however the stator section encompassed by each coil is where the flux will be developed, either North or South. The back of the poles could couple through the outer stator regions however, in the inner stator regions, where the fixed rotor is not present, that path could only complete locally N to  S through the air, although this will be a high reluctance path. As a given pole starts to come into registration with the rotor, this provides a low reluctance path to an opposite pole and so the pole flux is progressively coupled into the rotor, as the pole moves progressively into registration.

A more important consideration is the lack of a 4 pole rotor, which could couple more flux over a large region of the stator.

Hi Carrol,

One theory is that the angle of arrival of flux into the fixed rotor is different to that encountered by the Counter flux due to the load. This is only true over a certain angle as the pole come into registration.
The fixed rotor Counter flux will always couple through the path of least reluctance, which would be the same fixed angle into the stator. So you end up with a phase difference between the energizing flux and the counter flux.
