Basic Approach for the Design of Bearingless Motors

In this paper a basic approach for the design of bearingless motors is presented. The particularity is, that the rated values for radial force and power must be attained for the same air gap area. Starting from the known design of AC-machines the reduction of the utilization factor C by the radial force generation is considered. By an iterative sequence a reduction factor is varied until the rated values of output power and maximum radial force are reached.
