Muller Dynamo

watched the video. Really nice and educational ( at least for me ). Sounds like there is a way to time the coils to repel/push the magnets instead pull, just need to make some math for it.

Something to add to this:
The coil value L in the setup we are trying to replicate changes due to the external magnets, due to saturation effects.
This in combination with the optional current delay might be an interesting thing to look into.
One thing is clear from this: the coil resistance is a key parameter.

Sorry to quote my own post but person that asked did not respond and I think I need to expand...

In the looped under load vid, the mags around the circumference of the rotor trigger half of the motor timing. The strength or the size does not matter. It is half of the timing for the Hall circuit.
The rotor appears to be 12mm thick. The mag appears to be 1/3 that thick. So 4mm diameter. As far as the length, The rotor magnets appear to be approx. 4mm from the edge of the rotor.  So I would say The circumference mags are 1.5 mm thick or less.

Thanks that's what I was looking for. I noticed in the PDF south poles were facing out. If small neos they add lines of flux and I'm trying to get my head around all of the different magnetic flux lines associated with this thing. Thanks

You are pushing for improvements in efficiency, and well you should. I think that most folks here are still in a mode of trying to prove that COP > 1 is possible, and once that is proven, efficiency starts to matter a great deal more. If you want to get everyone's attention, offer an experiment that demonstrates COP > 1...you'll have their undivided attention.

I have offered such an experiment, over at OUResearch with one replication so far that worked and also showed COP > 5, where COP is defined as Pout / Pin.  It's a relatively simple device, entirely solid state.  Pout and Pin measured using a Tektronix 3032 DPO @ 300 MHz, a fine instrument.  Les Kraut built the replication, and it also showed COP > 5, on the same Tek 3032.  Both "current sensing resistors" (CSR) are 1-ohm.   (I would appreciate more feedback on my little circuit, which is similar to others I think.)

I don't mean to detract in any way from the work on the RomeroUK/Muller device, just wanted to share these results with you briefly given the "challenge" above by LtBolo.  And indeed, to challenge folks here to try a replication (schematic attached). Note that the SPICE simulation does not even give the right frequency, so far...  the simulation can't explain the results.

(where I go by "PhysicsProf" because I'm a retired physics prof... with a keen interest in these devices that may benefit humanity greatly.)

Good luck in your work on RomeroUK/Muller and other promising electrodynamic devices!

Quote from Magneticitist
a work in progress.. satisfied with the general arrangement as i have determined in the past this being one of the most efficient if not the most.
went closer to the Muller design by using an odd number of magnets and even number of drive coils. the gen coils however will be 8 total, maybe 7 havent decided. still brainstorming.
the coils im using are sewing bobbins with cores a little bigger than the other replications i have seen. im also using thicker gauge with all coils in series.
some are pushing some are pulling all triggered with one reed switch. i also have a tuning magnet but i will get rid of all that once i have a hall sensor.
i tried all possible coil arrangements as far as how ti series them and what not, and it turns out some of the better setups were some i would have thought would not work so well. sometimes this magnetic field business is tricky and slight "friction" in certain areas actually helps the momentum process.
