Just cause I think you guys are on the right track  (from romero's site) -

The real clever man is Vladimir Utkin who explained that for all.
We also need to understand the influence of each turn to the other turn/turns.Constructing  a coil must take into consideration many other aspects, not only the usual standard ones.
In your recent experiment 1+1 does not equals 2 . I have seen 1+1 equals much more and you will see it too with further investigation.The coil can also act as an amplifier when properly built.

Romero

Sadly, I have gone back to work (teaching) and will have little if any time for more experiments
till next holidays.

Good luck guys,

Quick update:

All my generator coils are bifilar now.

Adding biasing magnets to the drive coils make the input current drop (up to 40% if placed on both sides). But only if they are repelling the rotor magnets.

Didn't observe any effects with the biasing magnets on the generator coils so far.

@ M

Well, it is theoretically the same thing, but as i said i can't get any measurable signal out of that coil as can be seen in Plengo`s video.
If i put the scope across one i/p of the coil and the center point that connects the
two coils then i see the in-phase currents from one coil.

I wonder why Plengo sees any currents/voltages at all, because
if he had a mismatch of 0.001H between the 2 coils, he would only see millivolts induced.

It must be about the magnet being inbetween the coils and of course the windings carrying the opposite currents not being physically close.
As i understand it Plengo has his top coil clockwise and his bottom coil counter-clockwise wound. The flux direction that each coil sees is the same (in theory)

One thing is for sure the bucking coils ARE capable of creating a magnetic field individually (as Naudin showed) (during the Lenz establishment for example)
My bifilar coil CANNOT create a magnetic field. That is the major difference that i see.

Lol!  Excellent post!  You had me going right up to your final line and then I LAUGHED!.

Thanks for that. 

Everything in your post is really interesting.  Do you have an references to this that I can read?

Thanks again!

M.

PS.  I too have considered the possibility that I have only an RF receiver.  I guess testing will tell.

hi Mo

thanks for your interest in this info

there's quite a bit about this old system on the web, surprisingly - here's a link to the Wikipedia page:

   link-->http://en.wikipedia.org/wiki/Alexanderson_alternator

from your results, i'd hazard a guess to say that your system is acting more like a transmitter than a receiver, but i have very little HF knowledge, so i'll leave the final analysis to people who know

my guess is based on the data shape - your graph appears to be approaching one half of a resonant system response

however, the 'sharpest' peak (which i think is probably best considered as a 'dip') is now showing as you decrease the 'antenna' and the rotor is slowing

this means that the system is losing more of its energy - and IF that extra energy is NOT transferred to your intentional load then it must be output via the antenna (your other load graphs will show if extra energy is transferred to your intended load at the same rpm)

as you continue to shorten the 'antenna' then the RPM  MAY perhaps reach a minimum value and then start increasing with further reduction in the 'antenna' wire

it will be interesting to see if this happens - if so, you can see if the minimum matches some feature on your other graphs

this will be a natural resonance condition for the whole system

at some point after making these tests, it would be good for you to try using biassing mags (& washers) on your stator cores, like Romero did

i found that just this step increased my single gen coil o/p by 100% under load (my test photos & scope traces way back on the 'M Dynamo for experimentalists' thread)

but what you're doing now is very interesting, please continue what you & neptune have been discussing - it's great to see you all you guys doing some solid testing on your rigs (i've got a little side-tracked with the Prof Jones circuit, so my rig is waiting patiently for some brass rod and some more coils!)

in addition to what neptune recommended about getting the frequency checked by Radio Ham, you could also try placing a domestic radio nearby your 'antenna' wire when the rig is running, and sweep the 'dials' to listen for the loudest interference - if possible use a radio with AM, SW & FM bands (& LW if available) - the volume can be left pretty low so that usual stations are not heard so well - your signal (if present in a band) should be stronger


hope i haven't butted in here - you see i made sure to wait 'til neptune went off to bed!! 


hope this helps - keep up the good work!

If the two gen coils are wired in series-canceling and every coil parameter is perfectly matched between them, there should be perfect cancellation of the two generated emf's.

If any one of the several parameters (coil resistance, no. of turns, bias mag strength, core mu etc.) is not matched, then there will be a net emf across the two coils. The emf amplitude will depend on how great the mismatch is. In an extreme case for example where plengo is using a bias magnet on only one of the two coils, there will be a relatively large measurable emf.
