In prospective applications for active magnetic bearings, apart from performance and reliability, system costs are a major concern. The design of the proposed five axes active magnetic bearing system allows low manufacturing and assembly costs. Based on a simple modification, a radial bearing of heteropolar or homopolar type can produce radial as well as axial forces. Radial and axial forces are generated by the same set of permanent magnets and coils. This simplifies power electronics design considerably. Simulation and experimental results demonstrate the characteristics of the proposed design.
