Electrodynamic Bearing 3D

Application ID: 14485

This model illustrates the working principle of a passive electrodynamic bearing. An electrically conducting rotor rotating in a magnetic field produced by a permanent magnets induces eddy currents on the conducting rotor. The eddy currents, in turn, produce a magnetic field that opposes the magnetic fields by the magnets and induces a force that opposes the motion of the rotor. The radial displacement of the rotor is always balanced by the repulsive magnetic force, thus the rotor is rotating at the center with a uniform gap. The magnetic force is calculated as a function of radial displacement.
