Your welcome.

One thing that really needs to be addressed is the energy involved with the rotor spinning.

Lets say that your setup were solid state and used just electronic triggers, no rotor, and you got the same results. Now factor in the rotor. Did we get the rotor to spin for free?  ;]

Mags

That's why i made this rotor with little magnets.  I want to ''explore'' the bemf to see how much can i pull out from the same coil

Hi Mariusivic
Looks really good to me - more speed with less draw and you are doing something with that backemf now it wont wear out the switching with its "destructive transients' as some engineers call backemf spikes...obviously in the RomeroUK machines, you could slam that backemf into that opposite motor coil circuit tha could be runnig off a cap too...and then the oppostive motor coil circuit goes back into the "first" motor coil circuti too....maybe you can try this out with your test rig - so pull off backemf from the three small black coils an put it back into the "primary coil'....you might need to SWITCH OUT your backemf in order to do this (see below).
One way to swithc-out backemf/recoil is to take out the powerr from that first drive coil circuit (and 2nd too if you want as mentioned) with a FWBR having tis AC legs on the source and drain of the mosfet/transistor...then DC of FWBR into 12V battery (a battery her eas example fro easy experiment to be used as the load if you want to charge battery) .
run the motor on 24V....so you dump twice the voltage (plus backemf spikes) into 2nd 12V battery...this is fun to do as it does a hefty charge to battery, and can make the motor really race up in speed when you find sweet stop in timing - - -
for "timing" that is, put a AC-switching "bidirectional mosfet" (two mosfets connected at gate and source) on just one AC leg of the FWBR - so this bidirecitonal mosfet SWITCHES OUT the backemf into that battery - and you can play with the timing to find the really good sweet spot where it speeds up while hitting that battery...
substitute very large cap with that 12V battery to charge, or some sort of resistive load too like a light or something...(something like 2nd motor coil circuit like you are doing already eh!...)
OK there is something to try someday - other thing hate to say like broken record, is SHORT AT PEAK that drive coil after you do the switch-out FWBR AC leg style recovery...you dont have to use a FWBR - you could swtihc out with singel diode too...
On scope you will see the drive pulse, you'll see the spike dissapear when the backemf circuit works, you will see the turn-off point of the backemf switching too.....then along comes that NEGATIVE FLIP OVER peak period (not really a spike but when the coil reaches maximum negative voltage, then starts to climb back up to zero volts before next motor-coil pulse)...that is a perfect point to SHORT the motor/drive coil into caps....
anyways backe to subject of switching-out the backemf:
look for timing of around 5 degrees retarded for the "FWBR backemf swtich-out" to get a dramatic speed up - it works like an echo I think is what it does not sure why for sure though...you dont necessarily need to use a FWBR - just switch-out the backemf "somehow" into caps or load or 2nd motor coil circuit - dont just leave in "ON" all the time is idea here ....turn it ON only when needed, and/or when it causes a speed up...
also other reason for swtiching-out backemf, is that when you loop circuit back to another, you can do it wihtout everythign blowing up, since when the swtihc is OFF that circuit is isolated from the circuit that is ON so its a poor-mans way to do a "two stage output circuit'
swtihcing single backemf "steering" diodes will probably work bettter for looping one circuit back to another thant a fwbr but both ways might work fine depending on this and that...

Hi konehead!
Those 3 little coils produce little bemf...i can't use it. If i change them with another coil ( like the primary coil ) will affect the input current and less rpm.
I'm still trying to loop bemf from the primary into the battery with a simple circuit. The only way i can think of it is by using a solid state relay but again , i dont have one and they are expensive. Also dont know how fast they can switch on off.

hi Mariu
Maybe if you fill up a DC cap first, before pulsing your three small coils, there will be more power from them happening, plus you would get some decent bemf from them then too...(fill cap then pulse cap but dont fill cap same time as the pulse hits the coils - such as coil paralell to cap "all the time")
those three small coils must be wiping out the backemfspikes really quick with their resistance - there should be some really good uf value in cap to fill from the backemf/recoil of your primary that will not affect load and recieve/store practically all of the backemf/recoil....just guessing maye 220uf (pure guess)...then the size and ohms of the three small coils (or just one you would wind to accept this pulse from cap that size (somehow
also when charging RUN battery, or 2nd battery - fill cap first, and discharge cap to battery and ldook for arond 23V in cap on meter across it while it is doing its charge if chargne 12V battery (also dont forget  cap is disconnected from coils that filled them up in first place when the caps discharge to battery)
o in your circuits you tested, maybe try filling cap "in-between" the motor/drive pulse cirucit and the output circuit...
