Loss Analysis of a Bearingless Flux-Switching Slice Motor
Sprache des Titels:
ISMB14, 14th International Symposium on Magnetic Bearings, Linz, Austria
The bearingless flux-switching slice motor is a recently developed motor concept combining the magnetic rotor suspension of a bearingless slice drive and the topology of a flux-switching drive. In comparison to state of the art bearingless slice motors this concept introduces a magnet free rotor and relatively high torque generation. This offers advantages in industrial and medical applications which require regular rotor replacements and high temperature working conditions. This work will describe the working principles, prototype design, implemented control theory and measurement to determine the losses and evaluate the efficiency.
