"Self Running 900 Watt Fuelless Electrical Generator" Is this new?

@EMdevices,

No I have not tried resonance yet. What I initially was building was a high speed Bedini charger.
My motor coil has three windings. I soon discovered that (for some unknown reason) I could
not get out much back emf voltage from the third coil. The motor ran at breath taking speeds
but the output was very low. So I added a second coil to slow down the motor a bit. This coil
did charge my batteries. Then I got the idea of the closed loop magnetic field motor generator
and added a third coil with a Iron laminate from coil 1 to coil 2. This coil did ALSO produce
an output. So I guess that my idea of closed loop magnetic path in a motor does work.
It has not given me free energy so far though.

your system is actually optimal for trying the resonance,  and that is because it has a closed flux path, and high inductance.

what you probably have to do is to add another isolated coil for the motor function,  and leave the 3 coils you now have as they are.  You actually want to connect them in series to get lots of turns  (inductance goes up)  Or perhaps connect only two of coils in series and use the third to extract energy, etc..

Then get lots of capacitors and connect them in series with the higher inductance coil and speed up the motor to try and hit resonance.    Your small design might have problems though.   A larger diameter wheel will have a higher frequency for the same rotation if you can fit more magnets on it.

just some idea to try...

@EMdevices,

Attached is a drawing of the initial motor. The four Neos is flush with the Iron rotor in the center. The rest of the rotor
is plastic and the magnets is secured with a lot of glue inside the plastic. The rotor is 63 mm in diameter and 15 mm
thick. I use 8 Neo magnets 14 mm x 8 mm stacked two and two thus making a NSNS rotor. As I said before, the
output from the L3 coil is disappointing low. I think the main reason is that the motor coil is very effective when driving
the rotor. Another reason is that the transistor does not completely shuts off since the rotor is so small and the rpm is
so high. Just a theory.

I'm not able to test out more coils on this motor right now. I have run out of magnet wire and ferrite cores.
But I see no reason for others to try. The rotor is from a AC fan with the fan blades removed. I have also
removed the fan coils and laminates. This leaves a great double ball bearing rotor with a round laminated Iron
rotor in the center, One then glue on magnets to get a pulse motor. The modifications one have to do on a AC
fan of this type should not take more than 10 minutes.

The exact type of fan used is: NMB Model 4710PS-23T-B20, 230VAC, 1Phase, 50Hz or 60Hz, 9 Watt at 50Hz 8 Watt at 60Hz.

Here's some usefull equations:


To find the electric frequency given an RPM:


f = [RPM rot/min] x [1 min / 60 sec] * [N ecycles/rot] = ecylces/sec = Hz

where, N is the number of magnetic poles on the circumference of the motor and each produces one electric cycle (ecycle).  Remember, each pole, whether "N" or "S", will create one cycle of +/- voltage swing in a coil.   As the flux increases in the coil, the coil repels it by lenz's law, then it reaches full strength and the d phi/dt is zero, so no voltage induced, then as it retreats and decays, the coil tries to maintain the flux (again Lenz's law) so reversed polarity occurs.

Example:

RPM = 6000,  N = 10

f = [6000 rot/min]  x  [10 Ecycles / rot]  x  [1 min / 60 sec]  = 1000 Hz = 1 KHz

Now the trick is to create a resonant tank at 1KHz, by adding capacitors.

Assume the motor coils have an inductance L = 10 u H = 1e-5 H

We can calculate the capacitance we need as follows:

C = 1 / [L * (2 PI f)^2] = 1/ [ 1e-5 * (2 * 3.14 * 1000)^2] = 2 530 uF


Now, if you hook up that much capacitance to the coils, and spin the motor at 6000 RPM, you will have a matched condition where resonance will start to build up.  Watch out, energy galore !!!

P.S.  that's nice drawing groundloop. I recognize the old Bedini circuits I played around with. I'll have to think about how to integrate the motor and the resonace capacitor in the same unit so I won't have to use an external motor.

P.S.  it should be aparent that it might be beter to increase the inductance so the capacitance is smaller.  wire tends to be cheaper      also a closed magnetic path will increase the inductance considerably.   And finaly, the capacitors need to be AC,  not electrolitics.  I know the temptation is there to use electrolitics, but they are meant for DC and will overheat and blow up or bust and vent.

@EMdevices,

The biggest problem is to find the Henry value of my coils since I do not have a meter for measuring inductance.

To find the RPM is easy, just hook up the scope to the motor coil and measure the pulse repetition time.
Then I use f = 1/t. Knowing that my circuit will only fire on the North magnets passing I then
divide that value in two and then divide by 60. This gives me the RPM.
