Radial and axial forces of a passive magnetic bearing

Active magnetic bearings require sensors, actuators and controllers, guaranteeing a specified dynamic behavior. Passive Magnetic Bearings, on the other hand, use simpler hardware, but do not have any dynamic control, therefore demanding improvements in the design and optimization process. This paper presents a contribution to the optimization process and dynamic behavior of PMB with permanent magnets. A single layer and two double layer configurations will be analyzed. Simulation and experimental results of static forces will be compared. Finally, experimental dynamic tests will be carried out.
