Title: Don't lose your bearing on bearingless motors: introduction, developments and potentials

Wolfgang Gruber received the Dipl.-Ing. (M.Sc.) degree in mechatronics and Dr. techn. (Ph.D.) degree in technical sciences from Johannes Kepler University (JKU), Linz, Austria, in 2004 and 2009, respectively. Since 2012, he has been an Assistant Professor, since 2018 an Associate Professor and since 2021 Full Professor with the Institute of Electrical Drives and Power Electronics, JKU for Fractional-Horsepower Drives and Magnetic Levitation Technology. Since 2004, he has also been a Senior Researcher with the R&D company Linz Center of Mechatronics GmbH (LCM), Linz, Austria.

Prof. Gruber has developed the bearingless segment motor, reluctance motor, flux-switching motor, and PM Vernier motor. His research interests include new topologies for bearingless slice motors, their design, setup and control. Dr. Gruber was the recipient of the international Nagamori Award in 2015.
