Mesh density influence on eddy current calculation in the magnetic bearings

摘要

In this work, the nonsymmetrical 12-poles (AMB12) magnetic bearings have been analyzed. The 3D Finite Element Method (FEM) was used for the magnetic field computations and the nonlinear boundary problem was investigated. We describe the discretization process for the AMB modeling, [5]. The adaptation meshing method using the high-order finite elements was employed.
