Duplicate. Too much NSA and the like re-routing, one suspects. Makes the board a bit screwy. Happens quite often on this board.  Go figure.

Well the 5mm * 20mm Rod magnets arrived.

So knocked up another Rotor with 5mm slots.

Well atleast there is another configuration to try

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?

Hi Rob

Using 8mm Polycarbonate this end, but to increase the Mass I was going to cut another blank one and join them together if needs be, hence why I used a long Axle Shaft.
But also have sourced some 20mm HDPE now, which is not too bad a price.
So will try a few combinations, especially now AL has a theory about the plastics used help create the effect.

Nice find on the magnets btw. I am hoping mine will come next week now from the states, but if I get too inpatient, I might try some of those

Cheers

Sean.

Hi OC,

Thanks for the apology.

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.

He's put a lot of thought into things like the placement of bearings for greatest strength, to avoid wobble.  All his parts: magnets and bearings, will be arriving today.

I stopped by his shop last night, and he showed me the clear plastic he will be cutting the rotor and base from, so one can see through it to see that there are no cheater devices attached anywhere.  He got the $2,000 sheet of clear 1/2-inch plastic for just $250.

As I was looking at his drawings, he leaned back and pointed back to a carburetor sitting on the table behind him.  He's been working on the gun engine, coming up with a way to retrofit engines with that technology, which results in dramatic improvement in mileage.  He said: "Engines are so complicated. I've been thinking that we [also] need something more simple [to solve the energy crisis]."

After this initial open sourcing phase of showing people exactly how to build one of these things, I would encourage those who are able to work on improvements which they can then patent and take to market.  Doug will likely be one who will do that.  I anticipate that Doug will also help us in the initial phase of characterizing what is going on: testing such things as magnet size, distance, position, etc.

As I was leaving last night, he told me that it would be easy to scale this thing down and get it ready to mass produce for selling as a grown-up toy.  He owns and operates his shop, which has all the necessary components for such mass production.  He has several injection molding machines.  He said it would take about two months to ramp up for such production.

Feel free to post this report at the Steorn forum.  I'll post it to the OU forum.

I'll not pass your email to others.  There is one person I previously disclosed it to: the guy who was interested in helping us build a clear and complete set of plans.  I disclosed it with the caveat of "confidential."

Sterling

Sterling,

If that is in fact the case, then I apologize. After
my submission (which I did on 2 occasions, sorry I
can't remember the dates), I thought I monitored your
site pretty closely. I missed that entry somehow. And
apparently nobody took notice anyway, or someone would
have pointed it out to me.

Regardless of that, neither Al nor I was really
prepared for what happened last week. When that video
was posted, there were about 300 messages in our
development thread, which was our primary means of
communication. It tripled in size over the weekend. We
were forced to start up several other threads to help
deal with all the traffic.

This has been an engineering effort, primarily between
2 virtual people, with some synergy from the Steorn
forum community. It has worked out well in the end.

There are many replications going now. I'm sure at
least some of them will be successful. There will be
plenty of people to interview. And I'm sure you will
have much to report.

My goals have almost been met. In fact they have most
likely already been met. I simply wanted the idea to
get some serious consideration from some qualified
people. That did not occur in response to the
information you posted on your site, but finally did
happen thanks to a fortuitous discussion in the Steorn
forum.

I'm not looking to gain anything from this other than
a potentially brighter future.

This has all been a dream. Now I want to move on and
try to pick up the pieces of my normal life. If you
have any concern for my well being, you will keep this
email address strictly confidential. There are only a
handful of people that know it, and I ask them to do
the same.

Everything I'm willing to share is out there in the
Steorn forum. In fact, probably more than I really
want to share.

I will be posting a copy of this apology in the Steorn
forum for all to see.

Regards,
OC

"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.

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.
