@Ron

so my understanding

in the first drawing the drum would be magnetic (laminated or not).

the holes perforation could perhaps also be retrofit to the already made (old) disk   ( yes     exactly    remember    the ones you intended to let fly off to my garden) so i could play with the both Concentric bi coils and the new setup and make efficiency comparison.

the second drawing could be a non magnetic material against which high quality Laminated U-core could be fixed to constitute the magnetic track ( this idea perhaps to limit the weight and cost) The laminated U-core could be slightly curved to perfectly fit the drumcurvature and line up each other

yes in the french part of Switzerland near Geneva lake. I have 3 dogs and ,,,es lebt Münchner Oktoberfest

I_ron,

ok now we have some hot stuff to discuss here :

If this is the direction of movement of the magnet then the question is :

Why would the on-magnetisation ( red lines ) follow a different path than the Back-EMF ( blue-dotted lines) ?
The flow-path-condition are not changed during the onward movement  and away-movement of the magnet.
Why should the back-emf follow a longer path ( blue-dotted line in the rotor-area ) ?
I will take the shortest route heading directly to the backside of the magnet.
I am  talking here about the back-emf not the reactive-emf which happens later upon the magnet leaving the alignment.
Now something of importance I was posting already ( @broli ) : Even if i would try to measure with a scope I will not be able to track the back-emf. Onward-magnetisation and back-emf occur in the same field-location at the same time-frame.
What I mean is that you can not watch these two phaenomena seperately. This is very complicated stuff and we need to be very precise ( I repeat myself ).
Why do I mention this ? We loose time if we follow the wrong path. And according to the daily experience of
people working "hands on" (as Thane and I_ron do ) a concept is just 1 % of the effort. 99 % is used up in practical work.

Please bear with me folks. This development-phase is very important. Short-cut-decisions are dangerous in this respect.

The reactive-emf occures at a point in time the magnet is already displaced from alignement ( I_ron : watch out- it is heading twowards your face ) and thus the decreasing ( breakdown of magnetic field ) magnetic field enters the blank rotor-plate. The magnet will not be affected. Now the question is : what is the result of the reactive-component entering a iron rotating-plate ( even if it is laminated) ? Another drag I would guess.

Nevertheless - I agree @broli - we need skope-measurements in order to watch the point in time the reactive-emf occures and how this affects the coil-current.

So Laurent´s setup by using just small insular iron-pads on a plastic-drum ( or plate) -- where the magnet is mounted on - would bring us new insights. Where does the reactive-emf rising up in the coils go then ?
I would expect a better result using a plastic-drum because the magn-field has no way to exert another drag.
If  you would use a scope I would expect a negative voltage-spike which simply adds to the output-energy.

@Laurent : Have you been at the Oktoberfest and experienced the mass of drunken (human)dogs ?
                     Whoaaa...Whoaaa.. I have not been there since 20 years now..althogh it is just around the corner. I
                     do not like to dwell among drunken people.

@Thane

just sorry to disturb this thread with something probably completly off topic

but at this point of highest tension and intense brain storming, i propose a small break ,just 5 minutes

today DEK my jungest dog leave some papers on my desk. He knows that apart of a high efficiency alternator i am looking for a better electric motor for my ultralights.

so he suggested to consult the eminences of this thread to know if this stuff can be of any interest   or perhaps as already been studied ,by whom  and on which thread if any and if not is it worth to open a specific one?

It took me about 10 minutes to realise a very basic testing proto which i can't prevent me to expose here under

thanks for your patience,

@Kator01

no but  i visited Marienplatz and had good eating underground

Laurent,

Excellent drawings (again) I like the first one best, but this could also be turned to an axial one with
a brake rotor. I like the way you pick up on the suggestions (holes)!

kator, and all

I just don't know...but if what T reports is reproducible then something is happening with the Lenz
vector. There are several patents on "something" similar taking place with "lenz less" generators,
so it is a possibility.

Yes, I agree, the counter electromotive force (lenz vector) is almost exactly instantaneous with the
applied flux, but, like the applied vector will take a path of least resistance.  So maybe Mr T is
correct and feeding two cores from one core that is half the size or less does lead to a bottleneck
for the returning lenz vector?

We will have to do some tests for sure.

I completed the third rotor yesterday and want to wind a coil for it today. So I hesitate to jump
right in on this "new" concept until I have some numbers for the HV coil.

Big T is in California I imagine...did a trace on the rotor and it was delivered at 9:34 on the 27th.
Was offered a choice of two day service for Ca$123 or three day service for Ca$27... took a chance
on the three day... duh, didn't figure out 'till I got home that that was ground... still it seems to have
worked...only took four days... who can you believe?

So pretty exciting times for Mr T, Great that he is sharing so much with us. I won't hear any more
now until you do, so hang in there!!!

It has been my observation that the most potential is always generated at the core/magnet interface.
Here we have the induced voltage taking place at the far end of the food chain, as it were.

I_RON, DON'T FORGET THE INDUCED FLUX FROM EACH COIL IS ADDING TO THE INDUCED VOLTAGE IN EACH COIL...
