Zusammenfassung: The demands on bearingless drive configurations concerning performance as well as costs are high. The proposed concept of bearingless motors consists of concentrated coils in a symmetrical arrangement, which generate radial forces and motor torque simultaneously in interaction with a permanent magnet excited disc shaped rotor. Owing to the nonlinearity of the plant, the use of linear control design methods alone is not suitable for achieving a high operation performance. This paper introduces a general approach of a new radial position and motor torque control algorithm based on the theory of feedback linearization for bearingless slice motors. Experimental results demonstrate the effectiveness of the proposed approach.
