Les,
Were might I find these observations?
Checked under your login and didn't see anything yet you have 47 posts.

I have a lid but I know it is only first generation. It is 2 half circle arcs. One rests on the rotor magnets and the other rests on the top of the rotor. It has a simple balsa wood angle to push the stators down.
But I can't do that when my suports are falling off the stators

Hello,
Would someone create a flux diagram of this setup. Remove magnet 6 from the equation and reduce magnet 7's strength as it is not on the same plane.
TIA

If printed on a 297mm x 297mm this is almost exactly my setup.

"Hello Les,
I agree 100% with your statement about the fact the horizontal rotor magnet must have some length. This is so that stators can be lowered towards the middle were the flux is the weakest. If the magnet is to long it will change pole to n-s on the ends instead of inside/outside.

Say for a 4 inch length if you place a north face magnet stator withing the first 2 inches it will repel in one direction but if placed in the last 2 inches will repel in the opposite direction. movement of the rotor does compensate for this slightly. But there is a definite balloon effect around the ends of the magnet.

One thing that I notice most people try to do is use Neo magnets. I personnally think they are to strong to work in this configuration. The magnitude of the flux field is to great. You would have to move the stators a far greater distance awat\y from the rotor to get away from the balloon effect.

I also believe that 7 magnet stators is the way to go not 8. I am uploading a new pic of my layout. Almost 1:1, off a few mm. If you look at the way 7 magnets set to the rotor you can see it is always off balance especially as long as the magnet in from of the rotor is missing. I explain where I am working from.

I think you did very well with your tooling but again I would not use metal objects which again will effect the lines of flux more than orgainc or plastic will." - Emitremmah

Replying here to your post in the other thread so as to let that thread sink back down quicker.  I don't really have anything to add though.  I can see by your explanation why you need to redo the stators before anything else.  I think you're right about the magnet types/strengths and avoiding using a lot of metal in the construction, but I don't know that from first-hand experience or anything.  If what I said in the other thread about the Torbay design hasn't put you off, then by all means continue with it.  As I mentioned, yours seems to be the most accurate replication attempt so far, as far as I can remember.  I'm hoping that will make a difference in terms of the results you get, but at the same time, I don't want to encourage or discourage you.  I just want to see what you come up with.  Sorry I can't be more helpful.

Les.   

Well I have done some more.
I have routed grooves in some mdf to hold the stators. This meant that they are no longer the same height as the rotor. So I redrilled axle holes in the stators.
I have come up with the lid. It is from a ceiing lighting fixture. Heavy aluminum disk.
A video is on youtube.

This shows the action of stators without the lid pushin down.

In testing I believe that in order to lower the stators into line with the rotor will take more than is being delivered by the rotational energy. As a result I have now double the magnet face on each rotor attempting to increase the repulsive effect. I am in the  process of realigning and rebalancing the stators.

I have also started the cut on the aluminium disk.

I will need to bend this more appropriately but as a start it is not bad. The wheel it is attached to is about a 5kg spool of stitching wire for book staples. When properly balanced the single magnet faced stators can turn it fairly easily, though not as easily as without. I am thinking maybe the additional mass will help in a flywheel sort of assistance.

That's correct. And funny thing is it looks just like Torbays! except backwards. Stators above rotor magnet and down when no magnet.
It demonstrates that one does not have to be in contact with the top except when being pushed down.

The more I play the less thrilled I am becoming. 2 maganets per stator does not seem to increase torque. I actually seems to have reduced torque slightly. bit difficult to measure though.

Any ideas how to create a simple torque measure?

A spiral spring in the center perhaps that tightens as the rotor turns and a dial on the end of it. Something like that.  A bit of string attached to the edge then over a lever lifting a weight?  ....
