uggg   one more thing fora sense of direction..

lets say the litz 7 strand is 2ohm at 300 turns.

I dont have this wire.  But if you had all the strands in series, you should have 14ohm.  18v/14ohm=1.28amps

1.28amps x 18volts = 23watts   

Those numbers sound great to me.  Is this good watts err wut?  ;]   And thats if 18v is minimum with this config.

Night, sleep tight, dont let the bifi bite.  ;]

Its morning and i just reread this post.. My calculation was off here..    Was sleepy    lol

I was reading about Adams motors here http://www.free-energy-info.co.uk/Chapt2.html
and there are lots of similarities. I read:

" The drive coils should not be pulsed until they are exactly aligned with the rotor magnets even though this does not give the fastest rotor speed."

So maybe that's also a reason why Romero had no change in RPM.

"The rotor magnets need to be longer than they are wide in order to ensure the correct magnetic field shape and the rotor must be perfectly balanced and have bearings as low-friction as possible."

Maybe that's why Romero added a 5mm magnet on the 10mm rotor magnet, to get the right magnetic field shape.

"Collect the output power in large capacitors before using it to power equipment."

Already stated by Bold and others.

@ kEhYo77,
thanks for clarifying your results.
I think the three magnets on your rotor are located 120 degrees distant from each other.
2 question:
- can you tune the inductance of your inductor-coil by pushing/pulling the core in/out?

- the two connected generator coils, are those also located 120 degrees apart?
So that when one rotor-magnet is opposite of one generator coil, another magnet is exactly opposite of the other coil?
If this is the case, you may want to unmount one of the gen coils and slightly shift its location, so that the two generator coils are NOT located 120 degrees from each other.

reason for this: the current produced in coil A is delayed - because of the delay/impedance of the inductor -  and acts  as an accelerator in coil B. No?

So if you also "mechanically advance/delay one of the coils" , i.e. take it out of the 120degree position by a tiny fraction (halve the core diameter) - the acceleration effect should be enhanced.
Note: I presume, depending on the direction of rotation of your setup, the effect of the proposed change will either be acceleration or deceleration. So you will have to try both: shift the coil's location a bit clockwise from its present position and if that does not work, then shift it counter-clockwise.

I wonder if you can get more acceleration and electrical output if you do that.
Did you try that already?
Anyway, great setup. Thanks

here's the bearings we need http://www.youtube.com/watch?v=2R4QQmCY4JU&feature=feedrec_grec_index

I started a test rig a few weeks back by salvaging the head spindle and motor from an old SHARP VCR.  For those interested, the bearings in those are 696ZZ and are readily available.  They are used in many small, high speed, precision tools and appliances.

On a side note, I am able to drive that VCR spindle assy with the original motor quite efficiently.  This was with a lot of help from Gyula and resulted in very fine RPM control via voltage control to the drive IC and frequency control via a 555 that is also a required input to the drive IC.

Please note that I have disassembled other VCRs where it would be impossible to use the drum spindle and motor as I have since the motor was on top of the head and not underneath.
