The Master Of Magnetics "Steven Mark"

Dutchy,

I remember Mannix pic, what I am saying is you can clearly see in the videos that we have coils at 90 degrees.  From what mannix said, thats just something he drew as an idea.

From what I can see, its just a step down transformer.  20 turns and 1 turn or something.  You could have the length of the 20 turn one and send the right frequency down it to the be the right wavelength. I have already tried this using 100 meters of wire coiled up and send 3Mhz pulses down it with a single loop inbedded in it to be "squeezed".  I saw nothing strange.

Dave.

To be precise he said it's not Stevens, he didn't say it was his, but that don't matter.
I think the drawings aren't from mannix at all......
3 Mhz seems far to low as a frequency to obtain waveadding. Remember those waves go round at lightspeed! If you look at the example given its more like 300-900 Mhz to achieve the wavefront adding. The wavefront adding and timing is crucial. And I agree as long as you haven't got the right frequency the wave adding doesn't happen and you will only have a step down transformer.
I'm at work, haven't got the drawing but if you do have a look at the example calculation.

Dutchy, it depends on the length of your wire.

Light travels at 300,000,000 meters per second.  My frequency was 3,000,000 Hz so my wire is 100 meters long.  How else will the wave fronts be aligned so they can add?

Mannix was the length he needed in the example for the frequency he had.


Dave.

It's not about the length of the wire but about the circumfence of the coil!!!! so instead of 100 meters it is about 1 meter (roughly), hence 300 Mhz and not 3 Mhz.

I have most of the later posts saved.

This what you looking for?

Dutchy, I must be dumb!

Mannix says the wavelength of one turn is 1 meter.  His chosen frequency is then of course 300Mhz because light travels at 300,000,000 m/s?  What did I miss?

The max frequency my gen will go to is 3Mhz, so I made a length of 100m.  The width is not important, the width is just whatever it happens to be after you coil one wavelength up.

All it means is I only get one set of wavefronts.

Read it again!


D.

At the risc of being slaughtered by your knowledge , here is how i see it:

He's trying to put one (or more) wavelength in each loop op the coil. Not one wavelength in the whole coil. So to get a wave in each loop you need  lightspeed divided by 1 meter = 300.000.000 Hz . This then needs to be very precisely timed so all those waves are on the same position at the same time to add up. That is exactly what the example shows too: a coil with circumfence of 1 meter needs 300 mhz pulsing (no matter how many loops there are and how long the wire is)
Hope I made myself clear, else have a look at the drawing.....

Dutchy,

By the way, your comment about about sluaghtering you, derogotary or otherwise, I dont mean to appear all knowing since I certainly am not, as I have said before, I have qualifications in electronics and radio, but I am just a hobbiest, same as you, looking for FE.

Dave.

I know I was just kidding, I noticed you have a very wide range of knowledge. But on the other hand I know my share and if I wouldn't I would shut up. (unlike some others....)
Is it easy to get a 300 Mhz oscillator where you are?

Dear Stephen,

... To further our discussion, the reason you can not use small transformers within or at close proximity to your unit is because of the leakage fields of magnetic flux. They induce currents into nearby circuitry and most likely cause frequency changes in the operating point of the control unit. Remember when you inject even a small frequency component into sensitive frequency dependant equipment you can have a disaster. That is exactly what I believe is occurring when you try to use a transformer close to your units.  There will be all kinds of harmonics present within this field extending past the radio frequency range. If I were to compare the two I would say that toroidal transformers would be more susceptible. This may be contrary to common thought. Toroidal transformers have all their flux aligned with the grain of the steel used in them. This is the reason for their reduced size as compared with E I cores. When operated at higher flux density you can permit a smaller core. Toroids will always saturate quickly, however, E I transformers ramp up to saturation levels slowly. If anything, I would suggest you work with E I rather then Toroids. In either case I believe you will find that you will have to place the inverter well outside the collector coils.
