Muller Dynamo

[toranarod]

I've built a lot of Mullergenrators and done a lot of coil shorting on them too
before I get into how to do it, I think you guys should first copy the Romero mcahine as it is, and really take a close look at those helper/biasing/regauaing magnets behind the cores.
See if you can get the geneators coils to hit a load wihtout "reflecting" extra draw to the mtoor part of it (or make motor run on lower draw when coils hit load even) using only those magnets behind the cores first..

Anyways, with coil-shorting subject, you sould use BIDIRECTIONAL mosfets, since these switch AC (thanks Gyuala) ....simply hook the gate and source together with two mosfets, and the swtiching occurs between drain #1 and drain #2.
If you dont do this, you will catach only half the possible energy when coil shorting.
Also your mosfets must be high-amperage, very low resistance type or the extra resistance kills everything - using a solid state relay, or a SCR, are a couple of swtiches that will not work with coil-shorting since their resistance is too high...put mosfets in paralell to lower resistance even more if you want (Ismael trick)
this is why using a reed switch to do coil shoritng works so easy - they will swtihc AC, and they have very low resistance....but they also will blow up very easily too, so stick with bidirectional mosfets.
Also important thing, is to not put the extra-power/voltafge you make with coil shorting "directly" into the load...this will also kill all the big gains in power/voltage -

instead put what is made from coil-shoritng into a DC "collector" cap, after going through a FWBR....AC legs of FWBR across the coil-leads being shorted.
Then knock theis DC cap into you load - but do it at the same time the "source" (the coil bieng shorted) is disconnected from the DC collector cap - so there is no way the cap hitting load will affect draw to the primary.
this is called a two-stage output, and also this is confirmed with Ismael too, that this is way to extract power from coil-shorting.

Finally, you "should" have the short occur at the peak period - if AC, then peaks of pos an neg sine, if DC pulsed, at the peak of that DC peak you see on scope.
Woopy brings up very interesting idea - why not short all those out-of-phase gernator coils "at once" and forget about having each one have its own bidirectional mosfet and halleffect and bridge and cap - just treat all the those 18 out-ot-phase gernator coils like one big coil and short it see what happens - sounds like a lot of fun to me - this coil shorting thing is something I discovered by accident many years ago using reed swtich on 32 magnet mullergen and voltage in coil would go up from 20 to 240V in bilnk of eye so I knew it was something important,  but I couldnt do it "soild state" for years until Ismael told me to use very low resistance mosfets, and maybe 4 or 5 in paralell too - THEN it worked for me (that was last summer) I know Woopy and Romero did some youtube videos using reed switches and also Ovi has really nice reliable shorting-coil solid state circuit that he uses in motorcycle ignitions and did great video of getting 900V or so into cap and so Ovi knows all about it too (and has known for years too)...but really its all new-territorym the coil-shorting, and  nothing is set in stone - for example Ovi doesnt worry about the peak pereiods to short in his circuit while Ismale and I think its veryimportant...and now woopy talks about shoring 9 out of phase coils at once....so try eveything you think up - Laurents idea of shorting all coils at once sounds like great idea its simple might work excellent. 
In the past, I have run all out-of-phase coilsin series and used them as "one big motor coil" before and it worked very great making a mullergen into a motor (my "boat motor") - and pulling backemf made the motor run twice as fast too...very strange...
also you can run all those genratorcoils in series, and take out power like one big coil too why not and forget about all those rectifiers - another route of experiments!...and so might as well short them all at once too see what happens like Woopy did.
Romero is rectiffying them all at once, and also "regaugning" theire cores all at once with magnets behind the cores all at once too...

What is trying to be acheived here is a "no lenz" generator"  - get power out from it without affecting draw to motor...coil-shorting is one way to do it - lets see if those magnets behind the cores will do it too first... and then combine the techs later make gobs of power from nothing and lets get Romero back on the ball too once he has an army of looper-mechanics behind him to protect him and everyone else working on free energy machines...

Thank you konehead

this is information we can use this is what this forum is for. Well done.
I will give this a good try.

Hi Stephan

yes this video

betrween 2.14 and 2.24

at 2.24 you clearly see the red wire going from the FWBR positive to somewhere under the device .

And if you follow the Romero driver shematic it is clear that if you want to short the gen coils,  you have to connect the positive of the parallel FWBR to the emitter of the PNP transistor (that is to say to the driving coil of the bottom stator) and the negative rail to the collector ,that is to say the input negative.

I have tested and the shorting works. Now the tuning of all this is another story and is to be made.

Will go on this way to see what happens, because without this possibility i am stopped ,as i have tried almost all what was available without succes(always no litze wire arrived yet)

As a remainder, i got max 35 % efficiency, And Romero shows a cop 2 and more(because the lost in the DC-DC converter) . So something giant must happen here or it is a fake.

As i am only at the beginning of this road, please don't ask me too much scope shot. I need some reflexion here.

Perhaps other replicator could try this ,in order to see if it is OK

good luck at all

Sorry to hear no success so far but don't give up Laurent.  It's all in the details.  At this point you may want to ask yourself what details are different in your setup from Romero's.  Since we are dealing with something 'out of the box' here and not traditional EE we can't know for sure at this point what might be the one detail that makes it or breaks it in terms of success.  I know you already know this.  I just don't like to see the word 'fake' being thrown around because success has not found it's way into your build yet.  It may be the Litz wire you have yet to try or some other tiny detail.  As Stefan said the coil directions may be a big deal and I don't think we had much discussion on that with Romero before he left.  We do know if the flood of questions he didn't get every detail 100% correct.  There are lots of variables still to try.  Best of luck!

  BTW for the best price I've seen yet on acrylic sheets (on sale now even!) is www.freckleface.com  - silly name but good prices.  12" x 12" x 3/8" = $7.95 and 12" x 12" x 1.2" = $9.88.

Here are a couple of Romero's Posts regarding firing.
Why is it some of you guys want to start making stuff up? 

my apologizes if this has already been noted, I've only read this thread once through.

on the timing of the hall on top.
Romero's rotor has the magnets on the rotor facing north up, yet his hall is south firing. this must mean the hall is firing in interferometer mode yes.
so just as Romero mentions, this one fires after the magnet passes.
because of this invisible south, the hall could also be firing/triggering more than once before the next magnet.
Those w/ a working model must already be noticing this.
when taking the interferometry into account, the magnet strength and proximity to one another as well as the location of the hall (toward center of rotor or toward outer edge of rotor) plays a big role in the tunning.
the other thing that will play a big part is the location of the biasing magnet closest to the top Hall sensor.
these will bias the hall as well. you can strengthen or weaken the signal to the transistors base this way.
there is also a lag time from when the hall passes and when the power coil receives its juice.
these are just small points, but can be frustrating when tunning if they are unknown.

[toranarod]

this is my drive circuit.

I think this is a form of coil shorting you are talking about just the effect takes place as well in the drive circuit.
I have alway notice the motor runs faster when switch 1 is closed. remember I use a multi stage pulse.

OMG I get it ?

the answer has been there all the time.

will post if I am right or wrong
