About the Torbay concept (and I do mean concept)

[emitremmah]

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.
