Abstract :
A six-month feasibility study has shown that magnetic repulsion bearings (MRB) possess the load capacity and stiffness required by future high-performance turbine engines. The fundamentals of MRBs are presented, and the method of analysis used to determine bearing feasibility is described. It involved a magnetic finite-element analysis on a linear magnetic bearing, the results of which were applied to a radial geometry
