Fig. 2. Magnetic bearing made of two cylinders and two rings.
The bearing presented in Fig. 2 produces forces
between cylinders and rings in both directions, axial and
radial. Additionally thickness of non-magnetic barrier
influences on forces. Characteristics of radial forces vs.
axial shift between rotor and stator at three different
thickness of barrier are shown in Fig. 3. Respective axial
forces of barrier are shown in Fig. 4.
