Abstract
The paper presents a novel topology for a bearingless permanent magnet motor. This disk-shaped motor can be advantageously employed in delicate bioreactor processes. Both torque and bearing forces originate inside this magnetically levitated motor. Using 3D-FEM analysis, the optimal machine sizing parameters are evaluated with the goal to maximize torque while providing sufficient bearing forces to allow a stable operation.
