Working Magnetic Motor on you tube??

[ken_nyus]

One thing I would like to mention in light of Lumen's theory of operation for this device...

When I went back and read through all of the conversations at Steorn, I noticed OC several times asking Al to please change the stator rotors to ceramic bearings.

Al did not respond to this point at all. He completely ignored this request. Who am I but just another idiot on the internet, but I feel that Al held something back about the stator bearings, and it may be the effect proposed by Lumen.

But I think Lumen's theory turns the device into circular version of Newton's Cradle/Pendulum, with energy being shuffled back and forth between the rotor and the stator with very little loss. This was also mentioned by someone a few pages back here.

I'm not sure how Lumens theory accounts for acceleration, I can see how it accounts for energy transfer between stator and rotor, but not for acceleration. In other words it does not explain a source of energy, but only a mechanism for transferring it from one place to another.

Why would Al ignore an obvious flaw in a magnetic device (steel bearings 1/16" away from a very strong magnet), and why would the physicists at his job just chuckle and smile when they see a device like this?

One explanation is it is just a non-obvious Newtons Cradle.

Just some random, paranoid internet thoughts here.

In other news I did get most of my raw materials delivered today (HDPE, Delrin, Alum, bearings, etc.) so my build moves forward slowly as the saga unfolds!

Has anyone seen a graphic representation of this anywhere??


per Al - "But if you look at the later ones, you will see a 3.5 mm shaft instead of the 1/4-20 brass screw, and the 1/2 in hole in the rotor has been "plugged" with a Delrin insert to adapt to this shaft. The shaft is mounted in a dual ball bearing holder with a spring compression end-play eliminator, and the holder in turn is mounted on the base, in lieu of the brass screw. The rotor now simply slides on and off the shaft. For upside down runs I secure the rotor with a little retaining collar with a setscrew."

Thanks!

I have not seen any graphic, but I tried to follow any more info on this, and if I remember correctly, Al tried to explain it further, and also mention that this was a mechanism he took from the capstan(? or some other part) of an old reel-to-reel tape recorder.

hmmm can't find it...
I'm still trying to get a quote for parts machining but this part is stumping SPM...    (I see CLaNZeR's rig,) What's everyone else doing to support the rotor, what kind of bearings? how high etc?
is there a stock part(s) available somewhere?

Thanks

No one seems to be using a tapered bearing (conical bearing), but that would be my choice for the rotor, because both axial and radial forces are present.

Al mention that he could make the stator sync at 4:1 and 12:1, and that fits nicely with this theory.

If I remember correctly the 12:1 was gearwise synchronization.

I think it was in AGW locking 4:1 and 12:1

guys,

I was looking at the stills and videos of Al's unit again and it seems to me that some of the rotor magnets are not centered, or so it seems. can some one take a look and confirm this? I was wondering if this "imbalance" of the magnets may be a key.

I agree they appear offset
