Study on electromagnetic force in conical axial magnetic bearing

This paper presents two models of a single coil cylindrical electromagnet with a conical shape. The point of interest is focussed on the electromagnetic force, features and limitations of a such models. The calculations were realised with the support of COMSOL Multiphysics software. The 3D models allowed to expand knowledgebase about the electromagnetic force components not visible in the 2D axisymmetry mode.
