Muller Dynamo

[Rawbush]

@rawbush: Good one. This seems to confirm that the magnets can indeed beat Lenz. Can you also post the unloaded speed? And have you measured the output too?

I will run the same test again tonight when I get home from work, but will record un shorted rotor speed first. But I will add that I tried adding the bias mags to an unshorted coil and seen no changes, I also tried shorting the d/c side of the fwbr and adding magnets, this to produced no speed up.  This could be because the rotor/stator distance is not the same for both coils? Well I have to get ready for work, happy building today and will catch up later.
Peace

Thanks Nul-points and Itsu for helping us out here . Both of you made very useful suggestions . So it is probably parasitic oscillations happening . However , can we be certain that these oscillations are not an essential part of the Muller effect ?

Is this what your spikes look like?  This picture is of a coil pair (series-adding). You can also see some spike energy in between magnet passing. What I found to be the cause of mine was the coil was mounted real close to a drive coil and was picking up on its collapse, once the drive coil was disconnected the spikes went away. Could this also be what your seeing?

here is a great video with bias magnets and lenz law. http://www.youtube.com/watch?v=0x46bAPO24I&NR=1

It answers why we see speed up with bias mag in attraction.

after thoughts.. short the coil wire ends.. then position bias magnets to get top speed? Off to the garage

Thanks for posting this video link.
It inspired me to try to rewire my single bifilar pickup coil to simulate it seeing a "South".
In the configuration that i have it now, i see for the first time a significant speed-up under load when i attach a neo magnet at the end of the coil.
Also the rotor starts up to speed much faster, which indicates an aid in push.
I believe that this is mainly a magnetic effect to reduce the Lenz effect.
Remarkable is, that i see pretty much the exact same waveform that Romero posted. Maybe the waveform combined with the magnet is doing the trick.

I do not wish to be offensive but you waveform is not like Romero's.

Please see this pic (left waveform is from http://jnaudin.free.fr/html/mromexp.htm ):

@Mondrasek . The brain works slow when you get old . But I just realised something . If your drive circuit is oscillating at 375 Mhz , the frequency will be unstable and will change quits a lot with hand capacitance effects , temperature etc . That is why the pattern in your data is not an exact one . Remember it is an accidentally built oscillator , and is not frequency controlled by a crystal , phase lock loop etc . Fascinating nevertheless .
