TLDR
This publication gives a comprehensive overview over different concepts of magnetically levitated motors with slice-shaped rotors that differ in their construction and the way the bearing and drive forces are created.Abstract:
This publication gives a comprehensive overview over different concepts of magnetically levitated motors with slice-shaped rotors that differ in their construction and the way the bearing and drive forces are created After a description of the technical principle of the topologies the motor concepts are then compared by different criteria such as the acceleration behavior, the compactness and the complexity of the control The qualitative comparison is supported by performance measurements on the laboratory prototypesread more

Basic characteristics of a consequent-pole-type bearingless motor
TL;DR: In this paper, a consequent-pole bearingless motor is described, which has buried permanent magnets polarized in the same radial direction, and the results indicate that there is decoupling of the radial suspension forces from the drive torque when eight or more poles are used.

Classification and synthesis of permanent magnet bearing configurations
TL;DR: In this paper, a synthesis of passive bearings allowing original structures is presented, which allows to get passive permanent magnet thrust or radial bearings, but most existing devices are based on the same two or three structures.
