Muller Dynamo

...

Simple Example:
we have a rotor with NSNS and 2 coils, one to drive the rotor and one to collect.
the collector coil must have a core, any type but not air.
run it and measure the output of the collector and current going into the input coil
now to the end of the collector coil attach another core same type with the one used for the collector coil, same lenght too.
check the in and out - any change? good or bad?
check attaching only half lenght core - measure again
what about longer core.... measure again...
what about larger...?

Hi Romero,

I had tried this on my replication a few days ago and noticed the rotor does not slow as much as a dead
short load. But at the time I thought nothing of it because my collector coils are approx 1ohm, and substituting
a 1ohm resistor resulted in a similar rotor speed. Your suggestion however prompted me to return to the
experiment and document some interesting info.

First I found the no load rotor speed of 2287rpm.
Then with a 1ohm resister load, speed changed to 1530rpm @ 0.75A AC current draw across the resistor.
Then with a single collector coil as the load, speed changed to 1650rpm @ 0.77A AC current draw across the collector coil.

This is great news. We can draw more current from the load and/or at least decrease the rotor drag with a
collector coil in series with a load!

I then wanted to increase the core size as you suggested, but my cores are glued in, so I simply placed the
collector coil ontop of some pliers. To my surpirse, the rotor speed increased again to 1912rpm @ 0.67A AC
current draw across the collector coil.
Interesting how the rotor increased speed, but the load current draw decreased also. No real gain there I guess?

I then took it one more step and pulled out some Metglass C cores I had lying around from past experiments.
They already had approx 1ohm of 0.63mm wire coiled around them - perfect!
With a single Metglass C core as a load, the speed changed to 2220rpm @ 0.36A AC current draw across the Metglass C coil.

Finally, still using the Metglass C core as a load, I pressed the other half against it to complete the core
shape, and the rotor speed changed to full speed of 2287rpm @ 0.01A AC current draw. Amazing how the
load vanished completely, but so did the load current draw!

At this point a light bulb in series with the full Metglass C cores goes out completely. However the same
light bulb in parallel will light to the same brightness as if it were the only load. The rotor speed is the same
with or without the Metglass cores in parallel with the bulb. Interesing, but no real gain..??

Guys, please keep the photo and graphics  attachment size limited to 600 pixels horizontal.
This helps reading on small devices.

I did this during the experiments and the current remains the same.

OK, thanks for that confirmation.
So, what you basically say is that the extra capacitor does not matter with respect to performance.
At least, not the value you used.

oh yes, the capacitor value is very important.
Knowing the voltage and the coil inductance we can easily calculate if not exact but aprox value of the right capacitorto be used.
I will stop posting here as we are only talking about OU principles and ideas to be implemented not the Muller dynamo.
I will be posting in the other treads not related.

However, the most wild thing about this particular circuit was the input and output values that were observed. I set the load resistance to 20Ohms with the input voltage being 300V (assumed to be the open-circuit output voltage of my pulse motor's coils at 6000 RPMs). With these settings, the input power was only about 20-30W peak while the output power across the 20 Ohm load was close to 1.7 kW. Of course, I was quite skeptical of these results and attempted to reproduce the schematic in Multisim to confirm the results that I was seeing. I took a screenshot of the setup (Attached below).

Excellent work!  Now of course your are dealing with simulators but in real life once the power factor is maintained in this fashion the ambient will pump real joules into the coil so long as you can maintain a near prefect VSWR of infinity. There are several methods to keep the PF in the desired phase including switching on and off the load in synchronous mode, coil shorting, passive tuned, Sine clipping using zener triggers, bucket brigade delay lines and using several PF tuned stages to cascade the COP or in other words provide greater and greater source to load isolation.

Or you take steps to cancel the BEMF using bifilar coils or out of phase coils back to back.

Remember there is no in phase current presented to the source and therefore no lugging yet is capable of producing a very powerful magnetic flux opposite to that usually created by a BEMF event so this actually pushes the rotor faster just as the rotor passes TDC. This is the basis of rotorverter technology and the point being you do not have to have diodes in the circuit to have this effect it will work in pure AC as well as conversion to DC.

See Newman Motor runs on just a few PP3 batteries. There is hardly any current taken by the load yet it turns several hundred pound iron motor and most important observation is the magnetic flux generated by the motor coils is  so powerful it spins a magnet violently  over 12ft away from the motor!!  From my experience the conversion factor from VARS to WATTS  is about 10% thus your 1.7kw example is in effect ready for driving a 170 watt OU load minus 30 watts i/p power = 140 watts nett = COP 4.66
