Hi Khwartz

Hi Marius

For now let's play with a driving coil and gen coil. I did tryed to short the driving coil when is not pushing the rotor but nothing intresting so far. Just more current drawn.

I see, you prefer to divide in 2 parts for now, and then se for harder stuff, right?

The caps are filling like this:
- 56uF goes to 300V in 20 sec.
- 22uF goes to 200V in 5 sec

Thanks, but did they start to fill at 0V to go to 300 and 200V?

Hi Khwartz

Hi Kone

you almost got the formula right - but at the very end of it you have f  2  - (cant make a small 2 on this keyboard like you wrote)

...but anyways it is how many discharges within one second that you times it all by at the end of the formula - you dont square the freqpencuy or anything like that jsut times it all by discharges per second..

Ok, if you say so Kone, I believe you! more seriously, you were right I was wrong indeed! I've checked the dimensional equation I didn't checked before and it fits perfectly without squaring the frequency because P [W] = 0.5 * C [F = A*T/V] * (Vmax²-Vmin²) [V²] * f [Hz = cycles per second = T^-1], when simplified gives: V * I = P

You cant measure current without resistance...if you have no resistance across a cap, then the cap fills up without current really - only resistance really is the cap itself then -
good thing is, to make anything resonate you need a cap, just like you need a violin body to resonate the vibrations of the strings...without a violin body, there would be no resonance, without a cap you cant resonate anything electically....so having a cap in system is good, filling it without any resistance is good, and when you hit aload with cap, disconnect the cap from its "source" when the cap hits load pretty simple eh - this way the "source" never sees the load.

I knew for needing of cap for resonating, but now, it's even clearer to me for what we try to do and yes, i'll remember that the load must not meet the coil at any time

I cannot  understand a single sentence that Tom Beardan writes sorry.....

hehe, it's ok! for me too, his language doesn't look to me very academic, and I'm surprised not having been able to find any true mathematical formula as any true scientist would be able to produce to make any other experimentator to replicate and even predict the results expected. but I didn't have so much read from him, ans surely with bad translations too, so... I don't know if he knew exactly what he was doing, but I think he has kind of "physicist intuition" about what's going on, that he express could be to simpler to realise he is right in his way

Hi Mariu
have you seen the video of the "stargate" motor - its a conventional DC motor and he stacks neomagnets around it, and it goes super super fast (but I bet the cores get hot, besides the bearing-sleeves):
http://www.youtube.com/watch?v=5Xv-req4U8U

Anyways, I'll take some pictures of my romero-variant machine, with all the magnets in place - I'm not so good with videos right now...
basically now that I installed two facing coils in series for about 6.4ohms in coils resistance, the motor goes around 250-300rpm wihtout any magnets and with magnets, it now goes 960rpm which is huge difference -  only magnets doing this increase in speed!....draw to motor while it goes 960rpm is 60ma and 12V ...which is really low draw plus I have 5 coils on each plate, with ferrite cores too...Ihave only 4 magnets in rotor, going to put in 4 more for 8.....

The theory about the magnets in his StarGet-Motor, is to place them in a way that the magnetic field of the motor is not allowed to get out so that it stay concentrated within the motor, while the power comes from this intensity of flux.
Other sources says that the magnetic field of his magnet could even add to the existent one of the basic motor, but M. says it more about to avoid leaking of magnetic-flux.
Thane HAINS has a similar result but not with the stator but the rotor, not with magnets, but just with steal looped paths, steal like used in transformers, still to concentrate and amplifier the flux by this loop.
If it could help you Kone...

Many pages ago, someone (i think konehead) described what happens in the coil at magnet flyby. Scope shots helped in understanding at which moment the electrons (officially ) are pushed inside the coil.
Let me recall (for a magnet travelling over a coil from left to right, magnet and coil diameter similar):
The first peak (let us assume a positive one) happens, when the right end of the magnet hits the left side of the coil windings. =>The electrons in the left windings are pushed and can travel without counterforce in the coil.
When the magnet is in the center position, the scope shows a "zero". =>The electrons in both sides of the coil are pushed in opposite directions (right and left end of the magnet pushing electrons in the coil against each other.
The second peak then happens, mirroring the first one, when the left side of the magnet pushes electrons in the right side of the coil windings.

Therefore it is a clue for me, why most of the builders use same width (diameter) for magnets and coils.

The obvious point: if the width of the magnet is smaller (lets say minimum half) than the width of the coil, you will have four instead of two peaks, because the magnet is not able to push the electrons in the coil against each other at the same time. =>double amount of electrons are pushed by changing geometry alone...

Please let me know your opinions.

Thank you,

Hi all
here are some photos of backing-magnets behind the cores in a "Romero-variant" machine I built...it had 4 magnet rotor, but added 4 more magnets for 8 magnet rotor in some of the photos....the configuration and strength of the magnets behind the cores is very hands-on in way to find what gives the best performance, and is very sensitive and touchy - as removing one magnet or adding one too many will kill the whole speed up effect...sometimes bring the motor to a stop.  Before the magnets, the motors went around 300rpm , after the magnets, it goes 1200rpm which is really dramatic difference and the draw remains the same too....you need to spend hours trying different numbers of magnets in the stacks, using an rpm meter to gauge any speed up to find the best configuration,,there is no rhyme or reason as to why the stacks look as they do for the particular motor you have to experiment with all the possibilities and find what the motor likes.
3 of the photos are of an 8 magnet-rotor version, 3 of them are for the 4 magnet rotor version...this is why some of the bottom and top plates show totally different stacks of magnets
