Working Magnetic Motor on you tube??

[g4macdad]

A reminder to the replicators from the original thread.

Seecond, not all magnet/bearing pairs will produce the effect. I have 15 of the magnets, and 13 of the bearings. I have not tried all possible combinations of these, obviously. But of the 13 assembled magnet/bearing pairs, 3 don't seem to work at all, 2 are fairly easy to get started, and the rest are somewhere in between. Even the "easy" ones usually require several tries before successful engagemen

Third, the relative height of the stator and rotor magnets seems important. I don't know if it's because of my particular geometry or whether it is critical to the effect itself, but the magnets shouldn't be in the same plane--that is, I am getting best results when the rotor magnets are rotating in a plane that is just slightly higher than the tops of the stator magnets, rather than down and centered vertically

So, by "working" he understand successful AGW engagement, not so much the appearance of the effect, right? I remained with the impression that the successful AGW latching guarantees the appearance of the effect. What do you think? If that's so I for one am in a good shape, I can achieve AGW quite readily. What remains is to get magnets with the proper magnetic field ratio.

I believe the answer to that question is on that same page I linked at the bottom of my post.

My intention, though, was to point out that even with the same bearings and magnets he could only reproduce the effect with a small few. AL also mentioned the importance of keeping everything quite rigid early on in that thread.(I noticed how people have been using wild variations of his original design.) I think keeping things as close to the AL's as possible is critical in replication.

My 200 cents

Presumably we have all played with magnets and felt how when poles of the same type tend to 'slide' in a elliptical way away from the magnet held stationary. It also feels like there is some 'give' as the fields? come together or a 'bouncy' feel. Since most of the ways we take measurements of fields is static there is a tendency to think this that the 'give' between the poles is due to the magnetic gradient.

However we could theorise that not only does mass have inertia but so do magnetic fields.

Ok it is a mad idea and appolgise for posting this speculation here.

Hi Bill,

I ordered my Abec 7's yesterday afternoon.  I pick them up tomorrow from Mike.  They will cost just over $6.00 each.  Ordered for the stators.  They are the best.  I also have him pricing some non magnetic types for us. 

Hey Bruce,

Where are you getting ABEC7 bearings for $6? can you share a link or phone #?

Ask for Mike.  He is very aware of our project.

Cheers,

For those wishing to experiment with added mass in their stator assembly, one way to do it might be to add the mass in the bearings themselves.  This company sells ABEC 7 steel, sealed, skate bearings for $1.32 each:

They also claim to sell ABEC 7 ceramic, sealed, bearings for $4.69  ea.

Here in the bleachers, I'm not at all convinced that more stator assembly mass is the way to go.  There was a test published here several days ago that seemed to indicate that low mass stator assemblies (including bearings) actually allowed the effect to occur.  According to it, they facilitate quicker accelerations and decelerations, which help the stator be in the optimum position to achieve rotor acceleration - and the least optimum position to achieve rotor deceleration.  More mass would mean more consistant rpm, which would cause it to be easier to achieve AGW latching, but harder to achieve OU.

But... maybe that was wrong.  If so, these seem to be relatively very good prices for very high precision bearings.
