The new generator no effect counter B. EMF part 2 ( Selfrunning )

Hi Luc,

Have been thinking on the induced waveforms you have shown. I assume you tried to apply the same speed for all the 3 cores by your hand, right?

Thank you Gyula for taking the time to write your thoughts and comments.

Yes, I did my best to keep the movement at the same speed for each test.

When I first saw your scope shots, I recalled Naudin's test with two orientations for a coil, where he moved a magnet in front of the coil, then tangentially to the coil, see here: http://jnaudin.free.fr/images/magconfig.gif  from his site The Mini-Romag explanation ?
I think the right hand side setup shown in the picture gives a similarly shaped induced voltage you received, even though there are certain differences, I think the tendency is similar.
What I mean on similarity is that all 3 induced voltage waves of yours start with a small (negative) peak which suddenly goes up and peaks in one or two (positive) peaks, then suddenly goes down and change sign again and ends in a small (negative) peak. The order of the peaks (negative) and (positive) could be upside down, depending on the NS or SN placement for you parallel magnets, just like in case of Naudin if he had used a South pole up instead of the North up, his waveform would have started with a small positive polarity first as the S pole moved from left to right.

Yes I agree, it is similar waveform to JLN test but a much quicker change in my test setup as you have noticed.
The waveform reverses by moving the core in the other direction.

For your U core and the wide core the 'split into two peaks' of the single positive peaks comes about, I think, because these two cores are able to bridge directly the two magnets with overlaps and the flux of the perm magnets (mainly in the top part) would prefer closing via the appearing U or wide cores when they are just above the magnets symmetrically and most flux on top is "sucked" away from the coil core and goes through the moving cores. This is not so for the moving thin core that cannot form a shunting bridge for the facing magnets.

Yes, I would agree with your observations on why the difference of waveform when using the thin core which cannot bridge the gap between magnets.

Which waveform would make a difference in a generator, you ask. I would prefer the U shaped core but with its thickness matching the length of your magnets (now the U core thickness is less than the magnet length if I see it correctly). The U shape gives the biggest flux change out of the three I think and perhaps you wish to consider moving an U core under your magnet-coil setup too, now you show the U core moves only above the setup of course. This way the flux change could be even higher in the coil core. I mean two U cores moving alltogether as a rotor, sandwiching the stator magnets + the coil whenever they pass but then the total setup would become 'clumsy'...   Cheesy  surely a mechanically better setup could be devised.

Gyula

Actually, what I was trying to ask is, do you think any of these waveform would make a difference if this was a generator output and if so,  why?

The magnets distance is exactly the U core distance (center to center) The width of the magnets happen to also be the width of each core leg.

I agree, if we had U cores on each sides it should double or more the output.

Here are a few more tests... but not the Batman kind TK is looking for LOL!

The difference is, I separated the magnets so the U core can only cover one magnet to coil core and also tried it with a long solid core. The pics should explain the test.

It's the Batman Waveform!

Someone want to tell me why TK & Batman are never seen in the same room at the same time? Yeah thought so

@ kEhYo77
  in your setup could be very strong cogging

I've been working on this project for the last few days and wanted to share my progress.  My build is based on UFO politics cad drawing.
Please note that some of my design choices were based on surplus and scrap items in my shop and not necessarily the best engineering design.
My iron is not laminated but the cast steel should still give some results in testing.

For those of you who are in the energetic forum I tried to post it there but my account as VTOL is not activated yet.
