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 prototypes.
