Muller generator replication by Romerouk

Hi Rod,

Very good result!

Would be curious to know if you were to use a 1 Ohm high wattage rated resistor as the load, how the RPM would be affected if any? (It would be good to tune the 9 mH inductance by an equivalent capacitive reactance at the RPM frequency so that the load could be the pure 1 Ohm load resistance and not reactive. The cap could be either in parallel or in series with the coil, test should tell.) What is the input power to get that output?

Thanks, Gyula

Hi Rod,

Congratulations, great work.

So the ADAMS stuff is kicking in eh!

I picked up four of those inductors from Jaycar about 6 weeks ago.

Would love to know how you managed no drop in RPM

I changed the magnet size. from 30mm down to 10mm
and get the rpm up to 2000 and higher. its basically about timing where the magnets are with in the magnetic field when it changes polarity.
it only works at the correct load. I am studying this problem at the moment,

are you in Australia ?

From all the reading over at the other forum, I believe that's actually part of the solution, rather than a problem
If you have a 12V 20W bulb, then that would be the same as Romero's machine was tuned for. So, to my simple mind here, you want the 12V bulb as the load and to record another 0.98 ! Take the battery away and open a well deserved beer !

That fine tuning adjusting slide looks cool..a world of difference to my remelting of hotglue approach.

My Muller generator is repaired: ‪My repaired Muller motor generator‬‏ - YouTube
How do you recommend to wind my coils, currently they are about 200 turns of 2 strands of 1mm wires.

if you are winding new coils I would go with the slider coil setup.

just be mind full of coil to magnet ratio.

Hi Rod,

Yeah, I am near Parramatta, NSW.

Is the coil set at 6 O'clock the drive coil and the single inductor at 7 O'clock
the generator coil?

Also, the mags - you spec down to 10mm but 10mm x ???

What sort of power are you whacking into it ?

Circuit does not work

Hi toranarod
I follow you to provide circuit experiment
But it does not work,
Examination revealed: IRF9630 (G) and MJE13003 (E) 10K resistor connected between the cancellation and direct connection to work.
Please confirm the circuit belong to the right?
See attached images.
Thank you

I have checked the circuit. This is my lay out I will look over it some more

what is the supply rail voltage it was basically set up for 25 to 70 volts supply.
you must be above 20 volts for it to function properly.

[penno64]

Hi Rod,

Is that what is used for the setup at the top of this page ?

Hi toranarod
Thank you very detailed description of response.
My voltage is too low, Only 12V. 20V voltage regulator to work after, Circuit is working properly.
But: load (CFLs) are still only can intermittent flashes(flashing very fast), Not always continuous light.

How should I continue to the next?

just be mind full of coil to magnet ratio.

My magnets are 4.5cm in diameter and my cores are about 38mm in diameter. What is the slider coil setup?

Thanks

Hi toranarod
I noticed Muller replica circuit, In between Hall and the MOSFET driver, There is a 555 oscillator circuit, It seems the role is to produce more output tip - peak.

Hello to all,
I’m going to report my research for the last few days. I would like to point out that these are my observations and this data will require a lot more tweaking and testing before I can validate its complete accuracy but it is presenting some of the interesting results to date. I’m also planning on more changes to the design so I expect to see improvements and the configuration to look very different from currently.
The second thing I would like to mention is the similarity between my observations and the work presented by Romero, which I guess is a good thing as I am posting this under the Muller replica thread.
The major similarity seems to be that both motors reflect directly proportional parameters. Looking at the magnet to coil size ratio (in the photo below) there appears to be a direct relationship. I am using 10 mm magnets and they are facing the square core of 14 mm at a distance of 5 mm. This seems to be an ideal distance to get the best result. It is interesting how the working distance is half the diameter of the face of the magnets. Note that I am still working with over-the-counter materials so it is hard at this point to ascertain the correct iron core size but I am going to make and test a 10 mm core.
Other contributing factors include motor RPM and the correct amount of load on the coil. Coil load seems to be directly proportional to coil resistance, e.g. while a 1 ohm coil requires a 1 ohm load to achieve current draw with no apparent loss on motor performance, a 5 ohm load causes drag to the motor. I am yet to test these ideas sufficiently. With regard to the RPM as a contributing factor to the motor’s function, the magnet must move past the coil at a certain velocity to avoid drag. The RPM of my system under test today was (on average) 3200 RPM. If the RPM was not of sufficient speed a dead short across the coil would incur significant Lens drag.

Note to Penno64 – these are the circuits being used in the set-up.

Hi Rod,

Great work. Keep it goiing.

I was just unsure if the gen coil was the single 9mH inductor or some
fance footwork with the twin coil which at first looks appears to be drive coil.

Kindest Regards, Penno.
