should be able to do the same concept with these:

Hallo friends,

in the links for you a new OS concept for an PMM under;

I need help for re-calculation in a full version of QuickField.
An calculated factor of 1:3 made in the FEEM-Simulator is
absolutly not normal.  Thanks!

All the best!

Simulation I did in FEMM shows that this design does not work. The fluxlines looks different also because S and N attract eachother regardless of which side of the triangles. I made a circular model with 24 stator and rotor magnets, and simulated in 1 degree resolution. The result is 0 torque.

Do magnetic fields really bunch up at a point like this? The whole
purpose of a magnetic field is to spread out evenly. The first thing
someone should try is to show that this actual happens in using a
triangular magnet and one of those iron filing screens or iron filing
liquid. Magnetic fields don't self focus. It seems they would bunch
up on the trailing edge of the triangle.

This is how a simulation deals with this typ of shapes. All poles are N up, S down. Flux lines looks pretty different compared to the PDF's in the first post. Instead of repelling, they clearly attracts from both sides. No surprise really.
