Rotor Position Measurement for a Magnetically Levitated 500'000 rpm Permanent Magnet Machine
(2011)2011 IEEE Energy Conversion Congress and ExpositionIn this paper, we propose a DSP or FPGA based transversal flux eddy current sensor position measurement technique for rotors in high-speed electrical drives using active magnetic bearings. Compared to the state-of-the-art demodulation technique using analog mixers or rectifiers, the published method shows a lower circuit complexity and allows fulfilling the high bandwidth needs of highly dynamic systems as well as the improved accuracy ...Conference Paper -
Optimizing repulsive lorentz forces for a levitating induction cooker
(2014)2014 International Power Electronics Conference (IPEC-Hiroshima 2014 - ECCE ASIA)In this paper we study a novel way of induction cooking. Traditionally, an alternating magnetic field is used to induce currents in a ferromagnetic pan to heat foods. We use non-ferromagnetic materials and optimize the design for high repulsive forces in order to levitate the pan while simultaneously heating it and its contents. Our approach is simulation-based to study the influence of different parameters and to perform multidimensional ...Conference Paper -
