Bearingless and Reluctance motors

Abstract

Review of developments of bearingless motors, those are magnetically suspended motor with combined magnetic bearing function and a motor function, will be presented. Early stage research and developments, principles of permanent magnet types, such as surface permanent magnet, buried permanent magnet, consequent-pole, and homopolar are included as well as   induction and switched reluctance bearingless motors.

In addition, research on switched reluctance motors and generators for automotive applications are presented.
