Muller generator replication by Romerouk

@Woopy

How are you?

Yes, as you describe.

I take a coil from MO fan. I wrapped in the same direction as origianl winding,
approx 200 turns of heavier guage wire.

I biased the origianl core with a ring magnet and washer.

I simply used a reed switch to short the original coil at TDC for max output
from heavier gauge.

The coil on the left is an original - the one on the right is added winding.

Now I am testing with MOT.

Whaooo !

thanks for answering, i will do a rig to test

I can't wait to your result with the MOT and the giant biasing magnets inside

very cool

bravo

Timing is everything

@Toranarod
Rod that is great news! It appears that timing of the events exactly is the key to this working or not. You have to time the short energy input pulse perfectly with the pickup coil energy extraction pulse to see the magic. Your scope shots really helped to illustrate that. Romero probably stumbled onto it after many trial and error attempts.
There are still many unanswered questions but this should be our focus right now. Understanding this timing event is super important.

Rod any help that you and the other electronics experts can give those of us with less knowledge and experience will be greatly appreciated.
Thanks,

Lidmotor

The wave form diagram below represents the timing required for this exercise.
The green wave form represents the AC voltage being generated by one generator coil pair before the bridge rectifier. This is what the AC wave form looks like before we short or load the coils.
The yellow wave form represents the timing of the trigger pulse of exactly where the MOSFET transistor will be switched to engage a dead short across the green wave form, being the generator coil.





Now the wave form as the coils are shorted.

I'm glad other people are finding it also. this is much talked about but I haven't seen or read of many doing the experiment. It's nice to see the wave. thanks for posting that.



YouTube - ‪Romero Muller and Bolt's coil short speeds up under load‬‏
in the video I made of this, I only show shorting the coil outright. the rotor speeds up with an inductive load (light bulb) as well.
here are the items we've been adjusting so far that give results.

capacitor
bias magnets on coil
coil core - ferrite welding rods nails etc...
distance of coil to core. edit -> not coil to core - coil to rotor :-)
diodes on the FWBR

with each adjustment we are getting closer to regaining the full speed of the rotor.

Hi Rod,

thanks for the good news and congratulations!

In the meantime a member at ou com posted his 3D simulation findings and it sounds in accord with RomeroUK hints on the need for precise fine tuning, a narrow optimal RPM window for the rotor and also limits on the amount of the useful loads.
Here is his post if you have not read it:
Muller Dynamo

Thanks, Gyula

Thanks for some advertising Gyula
I started a fresh thread on 3D simulations of the RomeroUK rig at OU here:

this is only 1 drive coil pair.
l need to show a circuit diagrams to help me understand this.
its wave forms and circuits i have never contemplated building before.

I shorted the coils and added the tuned capacitor to the output and was able to get output current to 600 m Amps the voltage was so high it heated up the capacitor and destroyed it. the capacitor was rated at 160 volts non polarized.

there is so much to test.

The drive current was 100 m amps.

Is this OU? don't know as Power calculations are not available yet. I need to collect much more data to established an RMS voltage.

Great stuff Rod. 600mA? That's one coil; I presume when you double it for 2 generator coils you'll get to where Romero had on his Ammeter reading (first video) with just the rotor running, before he loaded the lamp. I presume that he was already demonstrating O.U (2 to 1 ratio) and the rest is easy!
Question then is Romero was using about the same number of components to timely short the coils, maybe with small reed switches or simple transistor that can handle flyback voltages. Exciting times ahead. Thank you all for your contributions.

cheers

I would go anyway to use 2 Coils in series opposite from one Magnet,
that one is influenced with a N, and the other one with the S Pole.
Then you would need in a 8/9 Setup only 9 Fwbr.
The output may can be catched as in one of Mullers Patent, in case he still have some.
Further it looks at one from His Daughters Video Präsentations, that he only shorts the Coils at a certain Point, that the drag is still not there the whole time. But it seems like, its not needed now in this kind of Setup.

Just to be clear, the first waveform is from your two coils, but just to confirm that those two coils are not placed such as the Romero device and you are only rotating the north field of the magnets across them.

I just wanted to emphasize this because some will otherwise say that waveform is indicative of the Romero device, which it is not.

Thank you for sharing.

you asked what exactly i was doing with my motor?
i saw someone post a video and the motor was of a type that i was wanting to make it is three phase and has permanent magnets for the rotor and having done allot of work on induction motors running with resonant fields i needed a desk top model and it fit the bill. it is high rpm low power and when driven in resonance should give me double the voltage output and enough amps to exceed the input it is my own project and requires me to learn new things and i have learned allot.
and you tought me something more that i was seeing in front of me it just wasn't going through my thick head.i do not claim to understand what or why it does what i saw just noted it did it when i got the right setup.
i take short cuts figuring these things out so folks here would not like my method or math i am sure of that but it works for me.
so i need to go back to studing op-amps but i still think about what you guys do and learn along the way and will help if i can.

That's not my scope shot
the video is mine. I have not scoped it I am still tuning. scoping will be one of the last tools I use. don't want to take the chance of boxing myself in. scope did that to me on the window motor.

PS - Romero said this is the start, then think of easier ways to do it. (paraphrase - not going to bother to look it up)

Hi Rod /ALL

This guy apparently got a result on one coil

Just a question

Let me see if I am understanding what is going on.

By correctly timing a quick direct short across the generator coil, the Lenz effect is derailed long enough so that the Lenz effect can not recover in time before the magnet has passed the generator coil.
Causing sort of a one way magnetic check valve situation at the generator coil.

The Lenz effect current from the generator coil during the quick, properly timed short, is fed as a pulse to the drive motor coil.
This way the rotor does not slow down when a load is connected to the generator coils.

The quick, correctly timed shorting out of the generator coil(s), is fed back to the drive motor coil(s), causing a over all gain in the power output of the generator.

Please correct me if I seemed confused here.

Thanks Steve 220

Ash,
what result did he get, all I saw him do was spin it up. did I miss something?
Zero sure is thorough w/ his build so far.

Redrichie made a nice find, shorting coils w/ an AC cap right on the pickup coil
