@Penno, you won't give up   

I also tried everything to get that waveform, I doubled the size of the rotor magnets to get that virtual south but no difference. Then I tried looping back the output before the FBWR with a diode and the wave starts to look more like it

here I loop back from 1 leg of the FWBR to the positive

Only 1 set of coils connected

@scratchrobot,

I think you should measure without any load, so also the FBRW disconnected.

With everything disconnected I get this

Hi all,

RomUk said:

My advice to all of you is to stop working on the Muller device  and just play with a simple rotor and 2 coils, one driving and one for collecting. When you will make that to speed under load or shorted then you can apply that to different even more simpler setups.

I know that most of you will say that the speed up will bring the rotor to the original speed where we don’t have the collector coil in place and there is no gain. Try and measure the speed before adding the collector coil then do the same when you shorted the coil. I think that is easy enough.

I've been thinking quite a bit about what he actually tries to say here....
Is it enough to have it speeding up under load OR is he implying it should speed up ABOVE free run (no collecting coil at all)?

I tend to think he means it should speed up above free running.
If that is the case then the question is, has anyone already measured speeds above free run with collector coil shorted?

Anyone clear about what exactly Romero means?

That was quick!
I read EM's comments on the experimenters thread, and he made a remark on the flat peaks that would be caused by clipping to the capacitor voltage, which makes sense to me.

In the case you had the FRBW connected, was there also a buffer capacitor connected as output?
You could do an easy experiment by connecting this up and parallel connect the load capacitor to a DC power supply, if you have any, and then vary the load voltage by adjusting the power supply, to see you get the peak clipping effect.
