Each coil has a double strand of wire, motor consumption is 100 mha. the speed is about 7000 rpm

What do you think?

Thats amazing !!!  ;D

i believe its an electric fan motor style.  ;)

I added the english translation of the spanish description from the video.

I hope its not a hoax :), if hoax the 2 like opposite magnets at the bottom are a hidden battery, but I dont think so, we weed to list all material we can see from the video and make one ;)

Hi All,

I posted this in the other thread, but it looks like a hybrid of a compulsator, if there are no hidden batteries. :)

http://en.wikipedia.org/wiki/Compensated_pulsed_alternator

What I find most interesting with the compulsator is this statement:

"...the compulsator could be used in non-pulsed mode to drive a tank with electric motors for limited periods as a kind of "quiet mode"..."

Now if this can be brought up to speed and run electric motors for a tank in short durations, it should have no problem with pulsing itself to keep the flywheel in motion.

Looks like he is using a gyroscope rotor as the flywheel and bringing it up to speed with the Dremel. He is also using tiny coils for low inductance. I don't see how the switching is done between pulse and collect through the diametric magnet.

Pretty interesting design for such a small device.

Some more info:

Iron-Core Compulsator

TIn the mid-1980’s, the first compulsator built for the U.S. Army electric gun program was successfully demonstrated. Named the "Iron-Core Compulsator" (ICC), the device is a 6-pole, rotating field machine which stores 40 MJ of kinetic energy at 4,800 rpm, and can repetitively deliver ten 1 MJ, 2 ms pulses. The ICC generates an open circuit voltage of 2 kV and operates at a peak current of 1 MA, resulting in a peak power rating of 2 GW. After fulfilling its stated contract goals by firing a burst of railgun shots at 10 Hz, the ICC has become a reliable CEM laboratory power supply for testing other components including high power switching for newer compulsators, and advanced railgun barrels.

Looks to me like he is using a Piezo crystal between two magnets, and he is actuating movement into the crystal with pulses from the coils. The crystal separates the two magnets and changes the overall field. These pulsed magnets then push on the bottom rotor magnets to drive it.

Just a guess!

I think you got it, I remember long time ago someone telling you can change the magnet polarity with current but I never saw one replication of this, if the crystal is the key that could be it

So the bottom magnets are changing polarity and make spin the rotor while the 2 coils are generating the current to power the crystal and generate extra current

Would you like to ask him, what he is going to do with this invention: to patent it or to start production for example. Making it only for the purpose of Youtube presentation makes no sense; looks like a hoax.

Hi All,

I do see something that seems a little odd. After re-watching the first video (http://www.youtube.com/watch?v=gECwKzRw-gs) at 2:01 he says it is putting out 4 amps? from those tiny coils?, something doesn't add up there. I have a large 1" diametric magnet and can get 8amps@120mv from a 10gauge coil @20krpm. So 60v*4amps = 240watts, from tiny coils, doesn't make sense.

I think he should replace the small lithium cell with a capacitor before we make any conclusions. The design looks very simple, and should be easy to replicate for those with a little more than average skills in electronics.

miniturising energy source, impressive!!!  ;D

nothing, i just want to induce this in your brain  :D

What I dont understand from his video his he talk about batteries, even show one but dont use them at all...

You mean that one side is magnet and on the other side its a small lithium cell?

Two magnets with something glued in the center between the two springs?

I would guess that its either a battery or a piezo.

It is quite clear that there is a battery cell the blue one on the bottom side in the first video (In the second video it is obvious that it is a lithium cell between the two springs). A regular lithium cell used in small cameras. On the top there is a cylindrical neodym magnet often used in brushless motors for RC planes. The flywheel is also from a brushless motor - probably an E-Flite brand motor. On this flywheel, there is magnets - if the red and blue colour is indicating South and North. There is pickup magnets on the top with very many windings, so the voltage will rise to 70V after the bridge rectifier and the charge capacitor. This is as far as I understand a clever design, but not overunity. The proof lays in the part where he by accident sort circuit the capacitor on the top. The RPM decrease, and never rise. A true OU device would increased RPM untill the friction prevents it to go faster. This device does not.

Because he uses a high RPM (Dremel) to start, it could be the start RPM is above the "friction" point you mention, so you could be right and wrong at the same time!
