Model order reduction techniques can be used during the operation phase of a product to generate virtual sensor outputs and enable diagnosis monitoring systems. This contribution shows an approach with example active magnetic bearing. The reduced model is calculate non-measurable physical quantity (here force) uses measurable (temperature) check for plausibility. As test case, dynamic force res...

Abstract A novel inverter supply for bearingless PM-synchronous motors with magnetic suspension allows the reduction of number power electronic switches. Hence, all six motional degrees freedom AC machines may be controlled via 3-phase topologies. In this paper, instead a motor consisting two half motors, one an additional radial active bearing is treated. Bearingless cylindrical rotors in cont...
