Muller Dynamo

I remember him explaining that at first he wanted to only use the small magnets for the halls but then he used the big magnets on one hall because that worked better.

OK, but then he probably also tested using the big neogens only and yet ended up with one attraction coil/long pulse and one repelling coil/short pulse.

That is strange. I havn't made a full series of measurements as you have yet but I can clearly observe o/p voltage increasing if the rotor is spinning faster.

Lol.  The quote from me sounds quite silly when I read it the way you did!  I do definitely see an increase in o/p voltage when the rotor is spinning faster.

What I was trying to convey was that is see no "unusual" relationships between o/p V and RPM.  I originally built this system to purposefully have easy adjustment of RPM because I thought there might be a phenomenon (like phase shift) that caused an increase in o/p V at a specific RPM.  That phenomenon is what I have not witnessed.

I can confirm the bifilar coils putting out more than double the voltage compared to unifilars. A cap in series can limit the o/p current so a load doesn't slow down the rotor.

Can you please confirm the inductance of your tested bifilar and unifilar coils?  Also, do they have the same number of turns and are they the same size?  And finally, were they adjusted to be at equal distances from the rotor?

Edit:  One more question.  How are your bifilar coils wired?  Tesla style (end of one wrap connected to beginning of the other wrap) or something different?
