Muller Dynamo

[mikestocks2006]

Hi Mike!
In this experiment i didn't short the coil. The led lights only from the BEMF and couses de increase of rpm. Becouse I'm using a reed switch i can't measure the input power( my metter goes crazy).If i remove the bolt, the rotor doesn't want to spin(maybe becouse the coil is to far from the rotor. I have noticed that when the led is conected the spark in the reed diseppears. I know that this is not the romero setup but with this rotor i can do more experiments that leads me to the understanding of his muller dynamo

Hi mariuscivic,
In your video http://www.youtube.com/watch?v=EmNuZ0UIk5Q
It appears the prime mover (driver) are the black appearing coil(s) on the left.
Is that correct?

If yes, then, there should be a rotational speed without the “red” coil/bolt in place.
I’m only  inquiring about the rotational speed indication on your meter, without the red coil/bolt in place..
I’m not asking for power numbers.
So whatever the setup is in this video, just let it spin, and remove completely the red coil/bolt away from the rotor. Then what is the speed indication on your meter?
Thanks again
Mike

Hi Marisuvisic

those reed switches will crate sort of a double-pulse, like a "bipolar" hall effect as compared to a "unipolar" one, in that the leading edg of the trigger-magnet will trigger the reed, and then the trailing-edge too, so you get a quick double pulse (usually)

anyways the speed up from the backemf into that LED could be that the pulse-width is greater, and sort of now it has two motor-pulses, instead of one - this caused somehow by that LED (?) - and if so, then your draw would go up too, and so that speed up would be caused simply by more amps-draw from longer or double pulsing so nothing amazing "if so"

however if there is no extra amp draw to motor coil whern that speed upoccurs, and in fact shold be less amp draw if you have got the "backwards forces" of the backemf/recoil out of the motor coil circuit and into that light out of the way of things, then this would be really great thing so you need to know if the motor coils acclerate rotor because of more amp draw, or fact  the backemf doesnt hinder rotation anymore and all you need to know is what is the amp draw wiht LED light with backemf into and without...seems like yoru genrator coil with steel bolt is not "involved" right now, even though it might be shorted, and makeing some extra rpms like it does?

Hi everyone!

The more i play with the rotor , more things i discover  .

Tell me what you think:    http://www.youtube.com/watch?v=EmNuZ0UIk5Q

Hi mariuscivic,

use you meter on AC to measure the current between the 220vac and you transformer. First measure how much current the transformer uses or wastes (not connected to motor) then start motor to calculate how much it uses and then connect LED and diode to see if current goes down. Please also remove all the other coils so we know they are not being used. We don't need to see if the motor accelerates since we can hear it.

Please also tell us the DC output voltage from your transformer when the motor is operating.

Please do this new test; remove the LED and see if you get even more acceleration using only the Diode. I believe you will as I have also found 2 year ago that if you recirculate the flyback (BEMF) back in the coil there's a better push on the magnet.

Please make a video of the new tests.

Thanks for sharing

Hi guys!   

Thanks a lot for your comments. Tomorow morning i will try to measure the input power of the transformer with and without the LED; also i'll remove the coils that are not used becouse it creates some confusion. Next week i'll rebuild my rotor; i'm going to put 10 magnets on the same rotor size and the coils will be bigger. I have a theory that is being in my head for a while and i have to try it.

Hi mariouscivic,
Ok, this is really a very simple thing to do.

You have a meter that measures the RPM. You have red coil/bolt that is not connected to the driving coils, and also you have the driving coils.

What I’m asking is very simple:
Just remove the red coil/bolt completely away from the rotor and tell us what the RPM readout is.
That’s all.  No power measuremets or added components needed etc.

Thanks again
Mike
