Working Magnetic Motor on you tube??

[Omnibus]

Hi Sean,

I was just gonna tell you about using HDPE to be close to the original. Mine is HDPE, as Jason has it as well in his drawings. However, now that you have it why don't you try it with the plexiglass as well.

Hi Sean,
You are getting too good at making rotors. Cannot wait until you get your stator magnets!!!

What thickness of acrylic are you using for the rotor? 
The reason I ask is that 20mm, even 15mm acrylic is relatively expensive, but 12mm is so much cheaper.
It looks like 10-12mm from the above photo.

Stator magnets: I did want to say this until I won the auction, but I managed to get some diametrically magnetised 12mm dia.  x 6mm thick neodynium disk magnets from the UK, not rings, from ebay, hope to have them early next week.
I searched for:
Neodymium diam*



and found these with an alternative spelling:

Have you tried mounting a 12mm rod magnet (horizontal) on a bearing for the stator magnet and try this while you wait for your ring magnets?

I tried this and found that it locks up the all steel magnet, maybe a SS or non magnetic bearing would have better results. Although this was expected.

I meant bearing

Just posted this over at Steorn after reading AL's Reply Stating:
********
But I do not recommend using polycarbonate (Lexan )for any part of the machine--it's in the wrong place on the triboelectric series, if one of my theories is correct.

Nor do I recommend acrylic plastic (Lucite, Plexiglas, Perspex?) for the rotor, if the base is acrylic. Different materials should probably be used. I used HDPE which at the opposite end of the plastic tribo series from acrylic."
********

So where does polyethylene fall into the materials. Being in the States I was using this stuff
http://www.samsclub.com/shopping/navigate.do?dest=5&item=372450
since it is cheap and just down the street. I got some shop time last night and got the Rotor machined out of this material. I already started on the base. Maybe the material really does not matter.

I should mention also that Doug Furr, the Ph.D. Mechanical Engineer who built our 1/4-scale Perendev Magnet motor (with Brady's permission, but which we couldn't get to work) http://video.google.com/videoplay?docid=6189540769300973039, expects to finish today his replica of your magnet motor design built by Al.  He's sticking to the design as illuminated by Jason O, except he's going 1.5-scale, and his stator magnet is proportionally a little larger.  He's not using the Delran sleeve around the stator magnet either, so he'll be able to approach the perimeter more closely (in the process of characterizing the effect) after the initial replication is done.

Sterling,

Al seems to think the plastic materials might have
some influence on the system. He advises to use Delrin
or HDPE. If things don't seem to work quite right for
some reason, you may want to conside using the
recommended materials.

Here's hoping that doesn't make a difference and by
tomorrow there are several replications able to
reproduce the "Alsetalokin Effect".
