Muller Dynamo

Hi At

yes the way RomeroUKs mullergen rig speeds up under "contiuous" shorrt, or heavy load, is not the same thing as doing a quick short at sinewave peak, and collecting power that way into caps, then releasing caps to load when coils are disconnected from the cap itself...

I dont think Hector's assesment of the drive coil being the looping-reaon is correct - not to put down Hector however in any way - but Romeor has his generator coils and the drive coils as totally seperate circuits (as far as we know at least) and its the generator coils hitting load that makes for the speed up, and its nothing really to do with the drive coils here but its easier for them to puish that rotor around when te rotor speeds up under load that is for sure...however, if RomeorUK "secretly" did something with the backemf in the drive.motor coils and recycled it through the genrator coils and this gave a motor effect to genrator coils when under load, then that is something else again altogether -

I dont see any backemf recovery sort of circuit going on at all in the RomeorUK machine's drive/motor coils - so there could be one if anyone who has replicated it wantd to.

Hi Konehead,

Yes RomeroUK had 2 separate circuit like you said. I was sceptic with Hector theory first but by experimenting, I learnt more things and I concluded that Hector must be right.

By putting a small load on the generator coils, there is less drag (interaction) on the rotor (magnets) and the acceleration comes from this effect, nothing OU here. If you short the generator coil, you should have a better acceleration because the magnet has less interaction with the coil, nothing OU again here. If there is a too much big load on the generator coil, the interaction magnet-coil is big so there is deceleration and/or bigger input power (nothing OU). When there is no load, there is a strong drag. Remenber, RomeroUK said that the load was important too.

Then by putting magnets on the back of the coils, there is less drag from the rotor magnet and it help to presaturate the core (ferroresonance).

So the acceleration effect is normal (conventionnal). When there is no load on the generator coil, the drag is huge (idle power). Then by having the tuned load (only a slight acceleration as RomeroUK did) on the generator current, there is less drag and you can take power at the same time. This is where almost everyone get trapped.

During this time, the driver coils are doing the magic! It's possible to capture the extra energy (ferroresonance) because of the reverse diode. The extra energy is used to drive the rotor so it now becomes extra inertia (kinetic energy). This extra inertia is converted into electricity by the tuned generator coil. This is the way I see the system.

But I think it is easier to use your method (sinewave peak shorting) because RomeroUK had to tune the RPM to fit with subharmonic of the core ferroresonance. The best would be to use both for sur!

Just consider for a moment the position of the hall sensors

One triggers from above and the other triggers from the side.

Lets look at the one on the side (small magnets placed into edge of rotor). How much on time do you
believe you are using when triggered by these side mags compared to the generation time of the main
magnets going by?

The hall sitting above the rotor. This should be switching on the EDGE ?

Hi AT

OK I think I see what you are getting at - I describe it as exponential power increase, as when you load rotor and it spins faster, and when it spins faster it makes more power too into the cap that runs the motor, so it runs faster and faster as you load it "with itself", so that is why Romeor needed that DC to DC convertor, as he reported at first.....
anyways that reverse diode - I dont think Romeor has one in his circuit as he does "nothing" with the backemf/recoil of the pulsed motor/drive coil 9at lest I thought so - maybe I am wrong) -
but if he DOES run that diode coming off the mosret right back into the motor coil itself, then mabye that is what you mean here....lots of times you buy a off-shelf solenoid coil or something, and they will have diode already in there as standard procedure - it connects the "out" lead of coil right back to to "in" lead and will sometimes make a coil much more effecient - maybe sometimes possible to save 30% in draw doing this however half of the time this will work doing no good at all as all the reverse-spike energy is cancelled out immmediately by the ohms resistance of hte coil's resistance (depends on coils resistance and input etc).....anyways if this is the "reverse diode" you are talking about, then perhaps this is what you (and Hector) mean and that this diode really does its job AND MORE; cutting draw down and down and increasing power into the RUN CAP as the rotor accelerates.....

Hi Penno,

I don't think the ON time and the frequency of the trigger is what it appears to be. We should always look on a scope before. If RomeroUK had taken a scope shot of his driver coil, it could all be verified....
Just look at Chalamadad and his signing coils (KHz!!!). Almost nothing to do with the RPM. But RomeroUK trigger was more controlled than Chalamadad (at least it seems more controlled as the RPM was not affected).

Konehead:

Yes I mean the reverse diode. So the drive circuit need some power to drive the coil but with this reverse diode, some of the energy is going back into the cap and the other part of the energy is used to drive the rotor.

I'm going to bed.
Good luck
