Bearingless drives integrate the functionality of magnetic bearings and an electric machine into a single device. While this integration allows the realization of very compact drives offering all advantages of magnetic levitation, the design process becomes significantly more complex. This work deals with the numerous topological and geometric design decisions which need to be taken for such a bearingless drive. Additionally, the definition of suitable optimization targets for the electromagnetic design is outlined. The proposed guidelines generate a complex relationship of different dependencies which is then fed into an optimization process of a high speed bearingless disk drive which allows verifying the optimization results with measurements at two prototype drives
