Reactive power - Reactive Generator research from GotoLuc - discussion thread

[Farmhand]

I put together this crazy two phase generator setup.  With a bit of maintenance on the motor it will be much more efficient. I was thinking i could do some experiments with it since the universal motor can be powered from a Battery with DC or with AC from the wall socket via a power meter and variac. And with two phases I could compare differences between two separate outputs at the same time. It can do 50/60 hz or even up to 80 or 100 Hz maybe. Voltage traces of the two phases is shown on the scope. It's not as loud as it sounds on the video.

I put together this crazy two phase generator setup. 

Is there anywhere I can see how that thing is constructed?

I could not hear and understand anything you said.  Is that tight bearing really the only component responsible for that racket?

I am a high school student and surely don't have that much knowledge as most here have.
I have seen a video where gotoluc shows how he uses capacitors for having an overunity transformer, I drew a picture of how I explain it simplfied, is this correct?

I'd need to know more about the theory of operation of this circuit, such as the mutual inductance coefficient and the relationship of the primary LC tank resonance frequency [ 1/2π(LC)^0.5 ] to the AC power supply frequency.  I did not read this thread from the beginning.

This appears to be a simplified version of of Itsu's experiment.  It is different though, because Itsu forms a parallel LC tank with the primary winding and a series LC tank with the secondary winding.  Your drawing shows only a series LC tank formed with the primary winding. A series LC tank achieves minimum impedance at resonance.

The way you had drawn the flux seems to be correct conceptually, but you must understand that 3 separate fluxes do not really form inside the ferromagnetic core.  Also windings that do not cover the whole core, create a flux leakage that looks as in the illustration below.  The opposing action of the secondary winding (due to Lenz law) actually expels the flux from under the secondary and aggravates the flux leakage outside of the core.

P.S.
What country are you from?

Hi Gyula,
I followed your instructions, but i do not see a clear point where the right bulb starts to decrease while getting both coils closer together.

Did you ever do this measurement below?

If Itsu had searched for the precise primary LC resonance frequency (f_P) under load  - while the secondary winding was connected only to the output bulb (no cap),...

Did you ever do this measurement below?

I did, and in response i wrote this:

Ok, i toke a quick shot at trying to get a flatline response on the parallel (left) bulb during resonance by manipulating the cores inside the coils.
This should also manipulate the inductance like decreasing the capacitance as mentioned by verpies, but its not working as expected.

I am lost now what was "not working as expected" (to many things going on  ), so i will retry your suggestions.

Regards Itsu
