Muller Dynamo

Do you mean that the flux generated by the drive coil has the same force (or greater) taken by or generated by the gen. Coil? Hmmm...? Does it explain the no drag on gen coils when loaded?

No, the drag always exist. Because when you draw current from the coil, that produce a counter flux in the core.And that force the rotor to stop.


I think romero beat that drag force with a good drive coil adjustment. We should check that. When we look the video that he uploaded we can see clearly that he didn't put magnets behind the drive coils. And also he is using little cores too(not big as magnets...).


So here we can think that romero is saturating the drive coil when the magnet approach to the coil.That's one of the ideas. Another question that comes to mind is that when a magnet approach to the saturated coil, does it produce back emf ? Can anyone try this or are there any information about the saturated coils ?

I dont think so on the drive coils beating the drag.

He beat the drag with increased spacing between the rotor and the coils, while improving things further with the bias mags. This is all stuff he was working on just before he made the muller version.  Sure the drive coils do something well, but he always said there was nothing special there as to making it a runner.

A year ago I asked romero on youtube if he started the generator manually. He said "yes but it was really hard to make it start"(something like that). If there's less drag why would he say that ? It should be easy to start generator manually ?

Oh, I see what you saying.  Sure there is drag. But once the rotor gets up past I think it was 1200 or 1400 rpms, there was a speed up zone where lenz lets go. Thats what I believe was meant by lenz delay and all that.   And at those upper rpms is where the thing was able to run by itself. Not at other rpm ranges.

Personally I do the shorting at the sine peak just because I can get the maximum power, but you are right, I have tested with 3 reed switches positioned differently and I do get more spikes.
The reed switching is good enough for testing only but for a long lasting device must use solid state components.
I have also tried to short the wave all the way,multiple times, positive and negative using a 555  driver and i've got nice results.
I am working on a different setup too where one coil(few turns) is shorting the main coil and I get power from it plus extra flux to accelerate the rotor. Syncronising the 2 coils is a very important factor.
I will talk about this ideea once I finish the other things on my list.
I am close to have it running just with a capacitor, time is the only problem I have... but soon

There is so much more - just dig and you will find.
