at some point after making these tests, it would be good for you to try using biassing mags (& washers) on your stator cores, like Romero did

but what you're doing now is very interesting, please continue what you & neptune have been discussing

I tested backing mags early on and did note a HUGE increase in o/p V as well.  This was with my coils as close to the rotor mags as possible.

I then adjusted the coils fairly far from the rotor (matched the distance by scoping voltage on top and bottom coils in each pair and between the 3 pairs I have mounted so far).

With the coils very far from the rotor I could detect no changes when introducing backing magnets.

I have since adjusted my coils closer to the rotor two times.  After the first adjust closer the backing magnets still had no noticeable effect.  After the second adjust closer, I can again notice an o/p V increase when backing magnets are introduced.  You can also see how the o/p V wave form changes as the backing magnets are introduced.

I still have backing magnet testing in mind and just need to finish this intriguing antenna test.

In what ball park would your now extracted voltage and current be at what RPM (just out of curiosity) ?

You would have to specify at what load resistance you want that data (joke).

Here is the data I have at hand.

Thanks M.
That gives me an insight.
I am in my tests not yet satisfied with the voltage and current i get out of several individual test coils.
However i assume that the add-up of the differently phased signals
closer to the P2P values and hopefully the non-linear acceleration effect
of the biasing magnets on a full rig will contribute to higher extracted energy.
Therefore, even though i always avoid mechanical builds due to lack of tools and two left hands concerning this, i think i will put together a (probably crappy) bigger system with more o/p coils.

What would be good stator dimensions to go with a 20cm Rotor?
Would 30 cm stator plates be enough?
I think someone even made a nice laser-cutting bmp for the rotor earlier in this thread.
Guess i'll have to re-read it )

Do the shaft and the threaded rods have to be non-magnetic material?
Maybe it doesn't influence the magnets.

296 pages in 2 months? uauuuu, quite impressive!! i have been out to much time..

sory, i gave up in the 23 page!!

is there any sucessful replication of romerouk muller device?
