Abstract
A Lorentz force type magnetic bearing is introduced in this paper. It is intended for the magnetic bearing to reduce the rotating loss drastically. The rotor is composed of a ring type permanent magnet and back yoke which produce a constant magnetic flux in the gap. The stator is composed of four concentrated coils which are installed in the airgap. The bearing force is produced by the stator coil current in the constant gap flux. A simple experimental setup is made to confirm the operation principle of the proposed magnetic bearing.
