The Gabriel Device, possible COP=8

kk on the vortex winding.

We need to get a discount from Magnetec.  We are a group membership.
We are buying many cores, we deserve some discount for doing concerted business with them.  I will ask, I have done lots of R&D work and have managed this before.  I want other energy forums to join us in this general grouping so we may have better recognition of our purchasing power and then we warrant group discounts due to quantity buying.  If you have bought a core call back and let them know WHICH energy forum you are with.   I will call them tomorrow at the NJ office.

Hello I have tried building this device, but i am having a couple problems.

Nanocrystalline Core perm u= 20000
250 turns secondary 18AWG

3" Donut mild steel 2mm thick
150turns primary 18AWG

I am using a audio amplifier to vary the freq.
The results i get are, at 19hz to increase current

IN   25V @ 19hZ
   5.5A
   137W
OUT   10V
   0A no load
   0.2A load
   2W

I have attached photos of the build and scope photos.
In the photos red (input) yellow (output).

The two donut halves are insulated from each other on the centre , but the outer are connected.

What am i doing wrong?

Thanks
Matt

1) For mine the best result was when I don't saturate the inner core...
2) In your scope your current is highly distorted so PF is not equal to one even if your current/voltageare in phase. Harmonics are reactive in nature.
3) Try different load: too much load = very low output, too light = very low output also...
4) If not try to wind more turns at secondary for having higher EMF...
5) Good luck.

A very impressive looking device, Matt -- thanks for your careful work.

1. When you say, Vin = 25 V and Vout = 10V, is this the RMS voltage?
This result is surprising to me since you have 250 turns on the secondary and 150 turns on the primary -- so that one might expect Vout/Vin >1, when you find Vout/Vin<1.

2.  Do you have the "multiply" function on your scope?  If so, recommend that you take V(t)*I(t) and show that waveform, the instantaneous Power waveform.  This would be helpful and may provide insights (my scope has this function).   V(t) is the voltage drop -- the input or output voltage-- and I(t) is found from the voltage drop across a 1-ohm resistor, or an X-ohm resistor (then the Power is divided by X, the resistance in ohms.)

3.  As I mentioned in an earlier post, I think we need to vary parameters, do experiments in an effort to first UNDERSTAND how variations affect the Pout/Pin ratio (and Vout/Vin).

4.  I agree with SRM that you might vary the load and take measurements -- but I also suggest that you vary the FREQUENCY.  From 19 Hz (which is low) to say a few hundred Hz, and record results.

Again, the first step for me would be to  plot the Power waveform then evaluate it -- can you do that?

The graphs show voltage across the coil in the primary and the secondary
The currents weren't graphed , i used a multimeter
The voltages are peak to peak voltages .
At higher frequencies the current reduces as you increase frequency. The voltage at the output is not distorted at higher frequencies,
I have gone from 19hz to 20khz .

Also I switched the input to the secondary , and got a better transfer to the primary then in the normal case. The voltage was much higher

Mavendex said there should be no transfer to the primary if done this way

I may have to put a resister is series with the input to measure current and also the output .

Any ideas would be appreciated thanks
Matt
