The forces are calculated via the volume integrals in the airgap.
Has anyone who has looked at the 3D model taken a look at how the air gap is discretized/meshed near the center magnet ring. In order to get reliable torque numbers, one would need at least 3-5 meshed triangles on each side of the middle of the air gap.
From using FEMM software, I know that if the airgap is not meshed fine enough, the torque numbers will be inaccurate.
Hoping that some one who has access to the software can post a picture of the mesh around the two airgaps at each side of the center magnet ring.
Secondly, the patent text mentions that when a magnetic field is emitted at an angle phi with the vertical, the force will be exerted at an angle of 2*phi. I was wondering if someone can provide a theoretical reference for this statement.
Thanks!
