The bearingless flux-switching slice motor is a compact magnetically levitated drive featuring no permanent magnets in the rotor. In this article the working principle of this novel bearingless motor topology is studied and its operational behavior is evaluated using performance factors for bearing and torque generation. Three dimensional finite element simulations are performed to optimize a promising motor variant, showing encouraging results, that will be verified in the future with the help of a prototype.
