Muller Dynamo

[mondrasek]

It's ok about the caps no problem at all.But your results seems really weird. A lot of questions appeared in my mind about your test results. I need more data to answer them but i don't want to bore you with my questions. I think the time has come to make my own dynamo.I'm gonna make horizontal type as soon as my ordered items come. Thank you for your attention about my thoughts. I hope the idea of using voltage difference between capacitor and coil as a switch will lead us to a selfrunner device. We need more experiments, more calculations, according to these we need to change some variables as constants in our design.

One last thing that i can't stop myself asking to you is that do you have 180 degree phase shift between your voltage and current wave form? According to this question i will demand a circuit diagram of how you measure these wave forms.

Thank you and good luck with your work 

I agree that the results were very weird.  I was hoping they would mean something to you because they did not tell me much at all.  But definitely not what I could have predicted.

One thought:  The system is not very acoustically stable and may not be giving good linear results wrt RPM.  There are some passive coils mounted at all times and they have ferrite cores.  I adjusted the inductance of each coil with the ferrite so they have slightly different amounts of core projecting through and closer to the rotor.  There are 3 pairs of single filar coils mounted 120 degrees apart for balance.  But the one bi-fi pair is all by itself.  Also, the ferrite in the bi-fi is projecting about twice as far through the coil end facing the rotor and will be the ones that crash if adjusted too close.  As the system is adjusted with the coils very close to the rotor now, the rotor magnet to ferrite interaction is quite high.  A lot of cogging due to this interaction on even the unloaded coils.  And with these asymmetries, there are a lot of different vibration frequencies in play.  The system screams through many different acoustic resonant states as it winds up and down in RPM.  So where it settles may be slightly affected by the mechanical resonant frequencies of the build.  Plus my bearings may be grumbling through all the abuse as well.

Here is the schematic you demanded and a shot of the scope as it was set up and recording again.  I will not be using the scope or changing any setting for awhile in case you have any questions about the setup there that you cannot see in the picture.  I plan to tear down the mechanicals next to remove the bi-fi coil and set up again with the balanced three pairs of single filers.  Then I can test for COP with different loads and RPM to see if I am even greater than 1 as the cap switching theory suggests.  I figure with the correct load I must be able to achieve at least a COP of 1.334 if I want to have a chance to loop by adding the additional 2/3 of the coil pairs.  This is still questionable with my existing low wind count coils in my mind.

One errata correction:  The load in the previous cap tests was 390 Ohm and not 330 Ohm.   

All:  Please note that the FWBR is not drawn correctly below.  It has been corrected on the next page.  (I hope) (Sorry)

Thanks,

M.

Hi Mondrasek,

your voltage and current "looks" 180 degrees out of phase because one of your scope probes is not connected right.

Try flipping over your probe 1 ground and probe leads, and you will be in phase, as it should be.

I reckon it is way past time to jump ship

I wish wattsup could employ his skills and gather the detail need to replicate this -

At least it seems more realistic.

Just cant for the life of me figure how Romero got more than a couple of volts from his gen coils. I've obviously
used all the tricks I know of and short of using multifilar coils to raise the voltage, I just can't get there.

p.s. That totallyamped site is excellent - very understandable.

@Penno & Itsu:

I have experimented with serial and parallel resonance in the generator circuit.
Like Itsu i observe a 90 degree phase shift of current and voltage, but i did not observe a big voltage rise.
I believe that Romerouk has hit resonance on his generator coils to reach the required charge voltage for the dump cap.
It may be that the calculated resonance frequency is not correct.
In Itsu's serial resonance video, the voltage seems actually higher when the motor was running above the assumed resonance frequency and drops in value when he slowed the rotor down by hand to reach the assumed resonance frequency again.
Maybe i expect the voltage rise too much to be like in gotoluc's video here:

What are your thoughts?

PS: That argentinian motor may use the LC principle too:

and one last neodymium ring that functions as a magnetic oscillator, self-excited by a stage of captors. This captors commutes the magnet's polarities

Or maybe it's a translation mistake and he rather means that the caps feed
the i/p again.

Thanks Itsu.  I had not paid much attention to the fact that it "looked" 180 out of phase since I was more interested in how it was displaying the "cap switch" phenom. 

Sorry to anyone that those scope shots may have confused.
