Muller Dynamo

[chrisC]

Hello all
I have many measurements watts current
I will share all measurement. I need some time to put them into a comprehensive format.

I have run the motor on 1 coil and 2 coils. On 50 volts, 12 volts 24 volts.
collected back emf. tried PWM timing, tried diffident coils may types of magnets on top under neath.
have seen some amazing results watched it do things I did not expect. I will make a video very soon.
after watching  CLaNZeR video I could see the RPM and Currents and volts. It was a very similar sight.  The High currents at those voltages are a worry.
if output can pass input it doesn't matter.

It has something to do with phase shift under load. I moved the phase by few  degrease by adding capacitance. this increase the output voltage by 35%
but the timing is still an issue I need to construct more electronics to run more test on this subject.  I think pulling current out at this right moment will
be an interesting experiment.     

the other point is there are still many test to do and configurations to try. its not over by any means. I work on.

I would like to hear from others with there results. Not theory and conjecturer black and white
recoded information.

Hi Rod:
Thanks for sharing your results. Looking forward to your comprehensive data. btw, when you run with one generator and one pickup coil pair using one hall sensor, say at 12V input what voltage did you get out at the rectified output? Can you let me know. I'm just about wired to test the coil pairs and I need some points of reference.

cheers

Just thought I would put in my opinion of what Romero might have been doing

The coil shorting video showed no extra parts.

Romeros email said he found one part that worked well for coil shorting.

After Romero left Stephan traced all the wires in his self run video and stated it looked authentic .......as I remember the only parts connected to output coils were bridges......modified bridges.

Could  a simple bridge be the part he talked about  in his email?

If I understand what goes on with a bridge....... it seems to me that it could be used to tune the overall impedance of the output.

If your coils are putting out 100 V and your bridge is connected to a 1.5 V battery you will have a very low impedance circuit.

If you connect the same bridge to a cap charged to 95 V you will have a very high impedance circuit

The bridge will act like an open switch until the pulse voltage passes the voltage on the output of the bridge......at that point any additional voltage will be "shorted" through the bridge



What I am saying is that the coil output voltage and the battery voltage have to be matched for best power transfer.

Edit

I forgot about the power supply he used to close the loop...
I thought he mentioned an input voltage but I do not remember what it was.
I do remember that the power supply was stepping down the voltage.

Resonanceman, That is a very good observation, and very correct, in theory.

This should show how "Tuning" must be matched to load, in order to get that "Switching" to occur correctly.  View the current through a diode to a cap from any "AC" or Pulsed DC source, and that situation becomes obvious.  This is where my "Fun" has been leading me, as I'm testing the coil arrangement without a moving rotor.  Far too confusing for me to make any definitive statements about what the heck is really going on.

To put it simply, "I don't know a thing!", Yet.  (Still working on it.   Paralleled diodes reduces the "Shorting Resistance", doesn't it?  How about reverse switching time?  See, lots to test, for me at least.)

With the excellent builds here, I am far too, well just say I can't begin to compete.  This prevents me from putting any of my garbage out for comparison.  I'll stick with MEG type work until someone proves anything either way.  (Yeah, I'm still caught up in building a "Replica", but am not nearly as far, nor near the quality of what's already here.   Fantastic work, guys.)

I cant compete with the building skills of most of the people here either...........but hopefully I can add a little insite  here or there.



My questions about why Romero did things the way he did  is leading me in another direction.....away from a Muller type motor
If I turn out to be right about a few things I may have to start a new thread.

Resonanceman, The video DID show those extra parts for coil shorting hanging under the table... @ 3:16...

My questions about why Romero did things the way he did  is leading me in another direction.....away from a Muller type motor
If I turn out to be right about a few things I may have to start a new thread.

Just thought I would throw out there one of the questions I have been thinking about.

Romeros Muller motor is N N

Someone else here has an older Muller motor that is N S

A     N S rotor should be better for use as a generator .....but it prevents you from using the magnets to reduce the sticky spot.

WHat if you used a N S rotor and added 2 extra rotors ....(.also N S) and timed them so that the magnets on them would come into play AT the sticky point.?
It seems to me that if timing was also used the size of the magnets would not be as critical ........and it looks like it might  be possible with strong tuning magnets and stubby cores to actually switch the mode of the core from attraction to actually repelling a little bit.

The timing would be important....... the dwell time would be important too.
If you are running in attraction or repulsion mode you want the same mode until the magnet hits the center of the coil (top dead center )......at that point it needs to change modes
Romero used 1 magnet on the edge of the rotor.....it looked like about 1/4 inch ......to small in my opinion.....dwell time about half what I think would be right.
He also used one of his main rotor magnets to  trigger his other coil..... to much dwell time in my opinion........but together they averaged out .

I say the timing magnets should  be half your   rotor magnets diameter

This is just theory.........but it makes sense to me.
