Lumen,

What RPM range are you working in in your video?

[blue_energy]

Hello Blue,

Thanks for the Link.  It will be good for our European friends.  I need a U.S. supplier.  K&J do not carry N35's.

If you find another, post it up.  Thanks!

OK - here you go, Bruce.  It took getting extra serious with Google advanced search, but I found them for you.  These two pages are selling .25"x.5" N35 cylinder magnets.  That means that they will *apparently* be slightly shorter than Als, but exactly a quarter inch in diameter.  Plus, they're both shipping from the US:

The RPM is controlled by a tiny motor from a constant voltage source so it's not very accurate. I do know from my homopolar disk tests that it will spin up to about 11,000 RPM.
I never tried running this up that fast and never calculated how fast the magnets would be going at 11,000 RPM but the thought of one flying out and hitting the back of your hand or some other bony part (I can't even think eyes) would probably leave a mark!

I have a new IR tach coming and should be here Friday. (cause I do calculations all day at work so I try to avoid them at home)

It will keep the AGW lock down to about 200-300 RPM. As it spins faster the waveform reduces in size as expected but way less than I thought would be the case.
In the video I would guess about 800-1000 on the rotor but wait for the IR tachometer.

Hi guys,

I started checking this forum after I saw Al's video on youtube, and i've been following the progress of the replications this last week. Keep up the good work and good luck with your rep's!

I editted Al's video to slow motion and altered the zoom/contrast a bit, thought some people here might be interested to see.

I fixed up CLaNZeR last video [http://www.overunity.com/index.php/topic,3871.msg70590.html#msg70590] and put it up here.
[http://ou.whipmag.googlepages.com/]
I stabilized the video so it doesn't shake as much. Also tweaked the brightness. If anyone has a vid that people think everyone here should see, upload it here [http://www.sendspace.com/] and i'll mess around with it then put it up on the googlepage. If its a successful video, i'll put it up on youtube as well.

Henry Absolutly brilliant,

one can see the stators shift and stall.

going for another look!!!

How can one save?

Hey Lumen, I looked your video over.  Interesting idea but there's one part I couldn't grasp.  Now let me make sure I'm understanding your experiment.  You're using a coil based tachometer to produce a signal that your feeding into the scope.  You then use an optical tachometer to drive a transistor that shorts the coil/tach at a precise time, correct? 

If I've got all that right then the part I'm not sure about is the signal coming from the coil/tach.  The signal you're showing on the scope is the change in magnetic flux from the stator, not the stator's acceleration/deceleration.  Speed information is a mathematical function that needs to be processed/calculated from the output frequency and amplitude of the signal - when processed it would look more like steps on your oscilloscope, not sine waves.  The signal from the coil/tach in the video is definitely raw unprocessed data.  You should get the same data by placing any small coil near the stator as it spins.  Shorting the coil as the signal starts to increase means your allowing current to flow as the north pole of the stator approaches the tachometer coil.  This will put a load on the stator magnet and cause it to slow down - taking energy from the system, not increasing it as what appears to happen when you get a latch. 

The lower frequency oscillation you can see on the oscilloscope is most likely the rotation of the rotor.  Since the coil/tach is in close proximity to the rotor, it should see two changing magnetic fields.  A low frequency signal (rotor) mixed with a much higher frequency signal (stator) will produce the same modulation your scope sees.  What would be interesting to investigate is what the two signals are doing when you have a good latch like in Al's setup.  I bet they are some kind of harmonic (n), octave (2^n), or triple octave (3^n) of each other - maybe even a standing wave pattern.

If this is not a hoax, as it is appearing every day not to be, then I would say all you fellows working on this have stumbled upon the mechanism in which the universe uses to create energy.  I've theorized that energy is created when two fields, being spatially 90 degrees apart and of the same make up (i.e. both magnetic fields, or both electric fields, or etc), interact without any reactionary force.  I'm working on a project to prove this theory but my setup would not be something easily found in nature.  I've often wondered how the universe would do it, I think this motor (again if it's real) explains it quite nicely.  As a matter of fact, I would venture to say that the latch should occur when the counter-spinning stator's center point (the half way mark between north and south) is in alignment with the north or south pole of the rotor, and vice versa.  If this is the case, then you guys will need to bring the two other gear-spinning stators closer to the counter-spinning stator....  and make sure that the gear-spinners are facing south when the rotor magnet closest to the counter-spinning stator is facing north...  hehe it might improve your performance 

Off to bed,
Charlie

Doug continues to be delayed in his replica by some unfortunate developments that he's had to attend to.

Meanwhile, he has been making slow progress in his 1.5-scale replication.

I've posted some photos and such here:

In the video I would guess about 800-1000 on the rotor but wait for the IR tachometer.

 

Several of us got this sub rev tacho meters that is giving a timestamp 720 times or more per rev. If we could get a sub rev tacho on the stator and then use an index mark on the rotor, we should be able to find the exact position of the stator when it is running in the AGW locking. Then we will see the acceleration part and the braking, and later if we help the rotor up in speed until we losses the grip, we can see how it was lost, and then modify the rotor or stator for a better match.


Yes, I know I should do it. I have all the equipment and the rotor -stator that lock in AGW direction, but I am swamped in work at the moment an hardly got time to follow this development, so until I get more time, I hope someone will look into this.

hi lumen and everybody

I'm a now studying for my masters degree in physics, and although everything I've learned says this can't work, I'm feeling optimistic. i have been following the developments over the last week, and i think what you have done, lumen, can be very enlightening. but i have some remarks.

i don't know how your tachometer is built, but I'm assuming it contains an electromagnet and a diode bridge rectifier. if it is so, the picture your are seeing does not indicate what you think. you would expect the same (or almost the same) signal from a magnet spinning in a constant speed.

so, from what we see on the scope, we can say that for every two "hills", the stator magnet makes a turn. so we can calculate its rotation frequency from that. it would be interesting to see the main rotor frequency as well, it might not be what we expect, in relation to the stator frequency.

i think a good way to look at it, is to look at the gaps between the magnets on the main rotor, instead of the magnets themselves. we can clearly define a "north" gap (a gap to whom the magnets on both sides point their north pole) and a "south" gap. now it is clear that the south part of the stator magnet is attracted to the north gap, and so on.

it might be interesting to try to connect the stator magnet to the main rotor with two gear wheels, so that it would turn in the frequency we set, and trying to give a different phase each time to the stator magnet in relation to the main rotor.

Congratulations on the good work so far! keep posting to keep us up to date.

Rather than using gears, maybe better to drive the Rotor and Stator with Stepper motors to adjust the phase relationship between them?

[xumed]

To try understand why there may be acceleration, please look at the principal discovered by the researchers of Inductrack.
https://www.llnl.gov/str/Post.html
http://en.wikipedia.org/wiki/Inductrack

Once a certain speed has been exceeded the drag coefficient reduces significantly. In the case of Inductrack something like 200:1.

With the rotor being spun AGW, as long as it exceeds the threshold speed the drag would reduce in a non linear way and so would be expected to accelerate.

The same may happen if spun GW fast enough

anyway just something i remembered from awhile back. Might help, might be totally BS in this case

[Discworld]

In all attempts of creating a pm motor I have seen up to now there is either the attempt to trigger it by an electic impulse or mechanically hiding a part.
When I saw this thing one thing came back to my mind. Most of you have seen it and came to the conclusion that this is nonsense
like this (sorry couldn?t find the video): http://keelynet.com/gravity/hamag.htm (just ignore the paranormal bull**** on the site)

Of course it only works because the hand is not fixed but exactly this is the trick. Know what I mean?
