Opis

This book describes the current state of the art in the developing field of mechatronics. Present research efforts and various applications are reported and open questions are discussed in the contributions. The aim at the symposium was to establish a common information basis for people working on magnetic bearings, in order to point to promising areas and help facilitate decisions on research and development projects and on investments in applications.
