This paper provides a comprehensive overview of different concepts of magnetically levitated slice motors with ring-shaped rotors that differ in their construction and the way the bearing forces and drive torque are created. After a general classification of magnetic bearings and the description of the technical principle of the topologies, the design(More)
Future application areas for bearingless pump systems will demand for highly compact and cost effective designs. This trend mainly has a major impact on the power electronics part of these systems. Up to now, full-bridge converters have been used in order to independently control the phases of the active magnetic bearing and the drive system. With the use(More)
