Abstract

This work presents the design and control of an 8-slot radial flux magnetic bearing. Design of magnetic bearing is carried out with coupled magnetic equivalent circuit model and finite element analysis (FEA). The magnetic design is verified with 2D FEA and good agreement between the two is obtained. Designed magnetic bearing is assembled into a system and fuzzy logic control is applied to the magnetic bearings to adjust the currents in order to balance the system shaft. The control is performed at the equilibrium position under different disturbances and detailed information about the working space of the designed magnetic bearings is provided.
