@MK1

I'm confused. Is it not.........

clockwise going up  =  counter clockwise going down  (same thing)
clockwise going down = counter clockwise going up  (same thing)

wattsup

PS: There are only two ways to wind a coil but there are four ways to describe the wind.
             

No its not only because of the magnet ... I will make a video to show you this weekend if i have time .

Hi all,

Still on vacation and I am writing from my phone. 

I believe romero fed back the dc output to ALL of the gen coils to produce a static bias on the coils.  I believe you want repulsion.  Only one mag sees one coil pair at a time.  Also explains high input current from romero.  Repulse.  Send one direction on bottom coil and opposite on top coils.  Coils a and b must repulse.

Cheers,

Bruce

@ Bruce. Enjoy your vacation.
If you have a reference to where Romero said he biased the coils statically, please reference that if you will. There is enough stuff on this thread we don't want to go on a wild goose chase if unsubstantiated. We already know one driving coil pulse mutually exclusive from the other because of the Hall switches relative to the magnet positions and spacing. The question I really like to know is why the 1A current with no load? Answer this if you know for sure.
Thank you.

cheers

Have a look at the other replications. Most of them are around 8 to 15 watts depending how fast they spin the rotor. You going to draw a lot more current at 2500 rpm  compared to many only doing 1200 rpm. I don't think 12 watts is excessive for this pulse motor setup. If you REALLY want low power i/p then RV can run at 3000 rpm spin a rotor  twice as large as anyone has made here with huge puck neo magnets on just TWO watts using H bridge inverter driving 5 hp 3 phase induction motor....most efficient motor in the world using off the shelf stuff. This is not a baby toy its  man's tool and can produce hundreds of watts or even a  couple of Kw's OU  which is why Romero is scaling up for much more powerful generator.  There is nothing OU about the pulse motor coils its just a method to spin the rotor nothing more.

Thanks Bolt. At no load and 2 drive coils at 12.2V IN, it sucks 0.48A and my rotor spins very well with no noticeable wobble at 1420 RPM. (VCR bearings). I've almost identical specs. to Romero's spec. list although my coils are 500 turns and measure twice the ohmic resistance.

sorry if my 90 degrees out of phase thing was wrong I dont know if it was or wasnt and basically was repeating in my own lousy translation Bolts theory on how to get these to work  maybe it is 180 degrees really since the fields are run series-cancelling....magbye it is 90 degrees and I was right, and the idea is to jam each coil 90 degrees over so it comes out 180, and then everythig is backwards in first place and so it resonates (thats sort of what I thought Bolt was getting at) But I dont know....

Putting theory into practice, today I tried hooking up two facing coils in O-volts genratore/cancelling series, with rotor magnets passing between them,
then shorted them out with continuous short, and tried to get a speed up effect with different size series AC caps - nothing worked...

also tried to get SOME volts into a bridge and cap with the two coils hooked up like this in the "un-shorted" condition too, also by throwing in the sereis AC caps - I was hoping for someting to happen here  - but also nothing worked didnt try too long got a little discouraged with it...very counter-intutitive its all backwards like this making nothing at all at first, then trying to make something from it and I couldnt make anything at all but maybe next time...

also  am confused by the term bucking coils everyone is using in these mullergens - since there are different ways to look at "what is" bucking - to me this means to energize top coil in certain polaretioy with DC, and drive that magnet away (repulsive) and then do same thing with bottom magnet, drive that magnet away...so that is "bucking" to me, (with magnet inbetween) and also could be calle repulsive-mode too...(this is MOTOR COILS)

in generator coils with rotor magnet passing between them,  the term bucking (to me) would also be this same wiring direciton of coils but they are not being energized, but instead induced by rotor magnets.


BUT the relationship between the two coils thenselves, if no magnet between them, is now attractive actually, since the coils would pull to one another if the rotor magnet was not there....

so you can say the coils are bucking to one another, or the coils are bucking to the common magnet they both react to....

and one way is opposite wind direction than the other so anyways just thought to bring that up since when someone says they wired their genrator coils in their Romero relpica to be in series and bucking, I am not sure how they did it...is it the coils to themselves bucking or the coils to teh common magnet bucking?

while wirting this jsut made me think of something - wire the coils up so with no magnet between them they would push against one another type of bucking if both are excited by a DC pulse....

thinkgin motor coil mode right now to explain...

then run rotor magnet between them with coils hooked up like this - the top magnet will want to push and bottom magnet will want to pull rotor magnet so its going to hardly move the rotor at all, if at all.

BUT NOW distance lower coil twice or three times the airgap as top one...now the top magnet will do all the work and maybe lower coil would be "overwhelmed" at certain point and have no  opposite-rotation-pulling effect at certain distance,
maybe with help of helper magnets behind the coils, start to push rotor same direction as top magnet even though they "shouldnt"...adapt all this to gernator coil instead of motor coils....anyways another theory and thing to try out...
