I get a big speed up with no cores underneath the magnets, and no coils  - just magnets postioned in their postiions where eventually they speed up the rotor

Hey Kone, I can confirm this. I once attached a magnet to one side of the bearings housing and the rotor speed would climb. When I added more magnets the speed would increase further up to a certain amount.

Hi guys
I have speedup with the magnets around the rotor  but in my case , the magnets are reducing a lot the vibrations and this is why i got speedup Isn't this your case too?
I'm exploring the potential of my new build and all i get is lenz from the gen coils  .
But the interesting thing is happening with the magnets behind the driving coils. It speeds up with a load on the gen coil.
Below are shots of the signal over the driving coil with and without magnets
I also remember that Romero said  all the gen coil are becoming driving coils and that only two pairs of driving coils is enough to make it self run.

Hi Crazycut
For sure it felt like a backemf/recoil spike, BUT there was no "electircal" connection between me and the coil, or the switching...so seems like it came from the CORE which is interesting thing.
I didnt have a backemf "steering" diode connected -  so the spike was there, ready to go somewhere - I guess it took a route through the core (ferrite and its non-conductive so tha tis interesting) then it hit a conductive-route of going through the flat steel washer. through the nickel plating of the neomagnet stack, into my hand and up my arm until my heart worked like a capacitor (just kidding but then again probably where it ended up)

Hi Mariu
Yes when it speeds up there is lots less "vibrations" and also sounds better but I dont think getting rid of vibrations is what the "speed up" magnets do - its more of fact that is what happens "from" the speed up - its not the cause of the speed up.
My romero-variants sounded super-sweet and smooth and quiet when I finally got it to reach 1800rpm @ 200ma draw but didnt film that...this was with all coils and magnets in place and it was very touchy moving a magnet a1mm this way would make the rpms drop...
I dont think there is need to put magnets "directly" behind the generator coils - but do think there is need for putting them directly behind the MOTOR coils, since this works as "regauging" the cores of the motor coil's core...so motor ocil and gernator coils are seperate things and behaviors to backing magnets and cores etc...
Seems to me the placement of the GENRATOR coils is one "entity" and the placement of the "stator speed up magnets" is seperate entity. (on generator-coil subject, not drive-coil subject) 
I got message from the mr R yesterday who said that he got speed up with AIRCORES, and flat washer only (no cores) on the generator side of it too...so this means the STATOR MAGNETS "behind" the generator coils, dont really react to the cores there, maybe not to the coils either, (!)  is my theory - it is sort of  a huge speed up you get when you put in place all the stator magnets, then the genrator coils go in "afterwards" and just dont put them in so close to the rotor magnets so that the lenz-effect will dominate - make the stator-magmet speed effect "dominate" (!) keep the genrator ocils and the power they make WITHIN the domination and "rule" of the speed up magnets....that last video I show, if I stick that genrator coil to close to rotor magnets, then lenz "takes over" but keep them a bit further away , and the speed up of the stator magnets dominates...
So maybe that statement by romeor was a bit confusing, saying the generator coils will "work" as drive coils....I bet actually the generator coils jsut generated power, but the MAGNETS that HAPPENED TO BE behind those generator coils is the "DRIVE" part of it - and because of fact Romeor "happened to have" his magnets behind each of his genrator coils,  he was assuming thats where they needed to be, to "react" to their ferrite cores....but in fact I bet if he had more time to experiment he could of got lots more power with new placements and strengths to those "backing magnets" behind the generator coils on the stator plates and in fact didnt even need the cores there, in the generator coils too,.....
motor coils is other story - I think cores needed there, and magnet right behind too...maybe magnet abit this way or that way too...
try taking out all your generator coils, get it to run on the motor coils only - use backing magnets on the motor coils too as you have now...
Then take a bunch of  magnets, and start sticking them on top of flat steel washers around you stator plates, in general vicinity of where the gernator coils were....stack the magnets up, to make more strength to them....somewhere you will find a speed -up point on stoator plate  - then stack more magnets on that stack, unti lit speeds up more and so stack more and more on that one point.....keep stacking until it slows and that is far as you can go, in THAT position...
then do it again - now using same stack size as you just found worked best jsut to give yourself somewhere to start at in "stack-size"... move this 2nd stack of magnets around stator plate until THEY give more speed up too...then jsut keep going like that - think of yourself as being taken over by ghost of Howard Johnson....1mm this way or that way can give dramatic speed up, or nothing at all...
what you are trying to create is a "hybrid"  Permanent Magnet Motor, with all the stator magnets you put down,  reacting to the rotor magnets and finve the huge speed up....but using the drive coil as means to keep it going while you discover where to put the stator magnets (the hybrid part of it)...
then put genrator coils in afterward, and dont let their lenz effect dominate - let them be under the dominion of the PMM forces....this is what I am seeing right now....impossible to say put the magnets here and there on stator plates of this and that strength and polarity too,  you have to experiment adjust and test but that is fun eh..

Hi Konehead
I still cant ''see'' how the backing magnets would help spin the rotor. Anyway, I'll remove the gen coils and cores and try to get some more speed with the magnets. I'm also interested about the  strange spikes in the midle of the pulse that occourse only with the magnets behind. It's not bemf couse this spike is in the midle of the pulse. Now i'm running the rotor  with romero's driving circuit couse is simple  but i'll try the  mosfets circuit.The driving circuit has a diode that recovers some power and send it back to the battery. I have disconnected the diode and connected a 4700uF cap and filled up to 20V. This is strange couse the pulse is only 12.5V
