FEMM simulation showing COP 3 and 7

Hi Vidar,

Interesting setups, I like them, although at the moment I cannot see how torque may develop between rotor and stator magnets, if you mean this is a motor setup?  Can you sometime test it with your magnets?

Thanks,
Gyula

Put a magnet inside a ring magnet, if aligned like shown it will be pushed to the center, fairly standard.

Vidar,
I like the second concept, maybe you could add to it by having the rotor repelling like you are on the first half, but then attracting on the way back in also. Just a mirror of the repelling area, but working in attraction. If you get what I'm thinking.

I thought I was going to be very busy this weekend but UPS will not be delivering until next week so I may find some time to run a few 3D models in Maxwell. I should quit work since it always interferes with my hobbies.

True, but the magnet must rotate to approach the center - because the magnet are rotating eccentric to the ring magnet.

Lucky for me I work with two of my hobbies: Loudspeakerdesign, and graphics (designing product catalogs, ads, flyers etc.) At home I spend my time at overunity.com, and flying RC planes and helicopters. My life is a hobby - except my wife. She tells me do do things all the time...

Here is a new design which use the very same, and promising, principle as the initial design in this thread. However, I have now designed a dual rotor motor.

To separate the shields at correct places, a cam from the rotors can control this. There must be a 1:1 gear which connect and sync both rotors (not shown in the drawings).

I hope this looks interesting. The attached pictures have a explanations in them.
