Muller Dynamo for experimentalists

[EMdevices]

Greetings fellow researchers!

I'm very pleased to see so many folks trying to replicate this Muller generator design.   I'm joining the fun as well, and I ordered about 100 disk magnets last week, which should arrive this week sometimes.

I am planing on building a few variations of the basic design so I can learn what features are critical and which are not.

Here's the theory that I want to validate:

Magnets in motion will convert extra energy from the subatomic world, as they pass a loaded coil wound on a ferrite core that is magnetically biased in opposition to the passing magnet polarity.

I was studying Thains motor and I think he does explain pretty well what is going on here.

Hey says that when the frequency of the rotor is above a critical point where the impedance of the coil (which is frequency related) is the highest, the ability of the coil of performing Lenz's Law is limited since the resistance is high and current is very low which reduces the counter magnetic field.

When the frequency is too low, the impedance is the lowest and therefore the coil is ABLE to pass more current and therefore create more counter magnetic field. Frequency will be ZERO at TDC therefore the impedance will be equals the very low coils resistance of below 5 ohms, therefore creating more current.

His coils are not small. They are high value gauge which means they are very small diameter coils, with resistance on average of 1.5 ohms. Which kind of corroborate Romero's coils. Very low resistance.

Now, with the relay coil that I did a video demonstration I right away realized that although they are good in creating 12 volts they will not be good for this particular Muller design, they are 150+ohms. The only way I could think of reducing the resistance is, again corroborating what Romero did, is by using many strands of the same wire in parallel so that the total resistance will be much smaller while keeping the amount of turns high to allow creation of higher voltage.

I am not concerned with creating lots of current yet, since once the rotor rotation is aided by the "high voltage" coil (such as Thains explanation), the current will be available any way. What I mean is the parameters for design Romero's coils are:

- very small diameter of wire to allow more turns and aid in high voltage generation
- very small resistance (below 5 ohms) to allow the generation of current to be very limited when the impedance reaches the maximum. Litz wires come in mind.
- proportional size coils to magnets since too little magnets or too big coils may not be the most optimal for magnetic flux/cutting wires relationship.
- cogging reduction by using biasing magnets

This video from Thains explains that pretty well. http://www.youtube.com/watch?v=czXmazZ4obs&feature=channel_video_title

Fausto.

Litz wires :

It's the fact that parallel conductors have a mutual inductance, so a changing current in one conductor induces a voltage in the other conductor.

high frequency more effect

[Tudi]

Interesting about Thains motor. I did watch the video about it yesterday, somehow i skipped it quickly without paying much attention to it.
About high frequency. Yeah, now that is a domain that contains a lot of magic for me. A lot of "strange" things happen at high enough frequency. Let's not forget that all matter exists as long as it has some "movement" at atomic level. Playing with that movement might alter even matter. Even magnetic field has a propagation speed, at high frequency you might get to a point where there is no back EMF or even magnetic attraction. Which makes me think you need a stable RPM for romerouk device to be able to finetune it.
Another cool thing i saw today is the programable magnets. These babies attract to each other to a certain distance then repel each other in a way to create an equilibrium state at some distance see example : http://www.youtube.com/watch?v=POc32aioLFE
maybe a similar design would help in creating a piston like motor ? Attract for a while then at equilibrium state slide them away ...

Maybe romero was using the extra magnets to obtain this effect also ? Let the coil attract the incoming magnet then using the magnet at the back create an equilibrium state to let it escape the back EMF more easely ?

btw, when having 2 paralel wires (litz) and you induce current in them, aren't they suppose to try to cancel out each other ? the magnetic field around them tries to oppose each other. This is why some use low wind count, or try to devise interesting wire configurations, or use loosed windings to separate wires a bit.

if I remember correctly each single wire of the litz is connected in series to have high voltage output, bit more complicated
