Bearings are pervasive in modern electric and mechanical. In my diploma work after the
presentation of the various types of bearings superconducting bearings detailed
presentation will take place. The main characteristic of superconducting magnetic
bearings is the levitation force between the permanent magnet rotor and the
superconducting stator. I will show levitation force characteristics of the SC-PM and the
upper PM-PM bearings. Knowledge of levitation force will be able to determine the
exact location of rotor and thus the stator can be in fix position.
