Magnetic Stiffness of an Axial Magnetic Bearing in 3D

Application ID: 27761


The model illustrate the technique to calculate the magnetic stiffness in a 3D geometry of a permanent magnet axial magnetic bearing. The Magnetic Fields physics is used to model the bearing and compute the magnetic forces. The Deformed Geometry and Sensitivity physics are used to compute the magnetic stiffness.

This model is featured and explained in much greater detail in the following blog post: Modeling Magnetic Bearings in COMSOL Multiphysics.

This model example illustrates applications of this type that would nominally be built using the following products:
