Larskro's magnet motor video was a fake - he admits on second video

Hi Ben,
nice to see you back experimenting.

What would happen, if you used IRON wire for the coils ?
Then the magnets would be attracted to the coils on its own
attraction and generate already induction which you could store via a diode in
a cap and when the magnets will be Top Dead Center you could
use the stored cap energy to pulse some additional copper coils around the iron coils
to get the magnets to escape from the iron wire attraction.

I guess it will only work something like this, if at all...


Regards, Stefan.

Hi Stefan,

Yes, if you used insulated iron wire for the coil, you could do away with the iron core but
if you charged up a Cap. via a diode, you would loose .4 to .7V as a drop across the diode
depending on the type of diode used. (you could use a reed relay here for no loss but it wouldn't make any difference as you would
slow the rotor down more!) You would also have increased losses in the higher resistance in the wire/coil.
You would have the drag or repulsion on the rotor charging the Cap. when in this generator mode.  You simply can't get away from the
generated EMF that causes repulsion in the approaching rotor if you use it or short it!  With the loss in the steel wire, the voltage drop
across the diode and then the resistance losses in the repulsion iron and copper coils, it would probably not fly. Over the last week
or so when I was directed to both videos, I threw basic theory to the wind and jumped in with both feet!  Immediately the
scope showed me the error of my enthusiasm and after a hundred different variations on the theme, I had to get back to reality. 

As to the size of the AA battery, they also make AAA nicads/metal hydride, etc.  Also N size if you really want to play around
with the illusion.  My hats off to two really nice pulse motors.  On the first original, just unscrew the two small screws holding
the coils on after removing the MuMetal base screws and show that the wood base is solid and the bolts are indeed solid. 
Pop off the heads on the "replication" and show the batteries inside immediately after showing it run.  That would clear up a lot of questions. 
I also don't understand the "tap" on the coils in the second replication.  The quest goes on!

Stefan, I never was away, just didn't have anything constructive to input.  As I get older, I watch more, read more and post less.

Nice to see you guys picking up on Adams motor

Just all of this thread screams to be pointed into Bedini SSG, with reed switch isntead of coil/hall sensor.
There is alot to be exploited in BEMF/radiant area from collapsing electromagnetic field, as those pulses act differently than conventional electricity. For example, if you have 2 generator coils winded on top 2 driving coils and try attach single diode to each when other side of those coils are common ground, when you try to catch BEMF spikes ant rectify them the diodes do not work as intended and act as short wire for BEMF... So you get current between 2 diodes cathodes. I tried this setup once more in my rewinded stepper mottor what got now generator coils on top of driving coils and clearly can see this effect.

P.S> The BEMF pulses are much higher voltage than initially (up to 10-20 times) with very low current usually.

Cheers!

The YouTube user http://www.youtube.com/user/skycollection has produced a video with the name
TETRAHEDRON (http://www.youtube.com/watch?v=aEjA8jlOOa0 )which seems to depict a motor (2 coils, reed switch, LEDs feed back generated electricity) similar to Larskro`s. The rotor turns for minutes and the claim is "no batteries". He promises in the video to add a third coil in a future experiment.

I could never get any information from skycollection, may be others (e.g. Spanish speakers) have more luck.

The contraptions built by skycollection are just beautiful, I wish I could build like that.

I know that is your understanding and a lot of people believe that, but in fact it's not true.

The BEMF pulses are much higher voltage than initially (up to 10-20 times) with very low current usually.

That's also another misunderstanding.

There are some people around here that may be able to help you and explain this to you.

Also, please note that it can be very difficult to describe schematic diagrams in text.  A simple diagram is worth 1000 words!

And it appears to be accelerating, with no batteries (or any other external input)?

Nice built as always.
Thanks for posting the link.
