Study on radial active magnetic bearing for flexible shaft

This paper presents the results of selected analysis realised for the flexible shaft with a solid rotor and 8 pole heteropolar active magnetic bearing designed for a such configuration. The calculations were realised with the support of COMSOL Multiphysics software. The 3D models allowed to expand previous analysis with eigenfrequencies and electromagnetic force calculated for a complete bearing as well for deviated rotor (as simulated orientation for flexible mode).
