Slotless Permanent-Magnet Machines: General Analytical Magnetic Field Calculation

Yves Perriard, Pierre-Daniel Pfister

This paper presents a general analytical model for predicting the magnetic field of slotless permanent-magnet machines. The model takes into account the effect of eddy currents in conductive regions and notably in conductive permanent magnets without negle ...

Charge disproportionation in RNiO3 perovskites (R=rare earth) from high-resolution x-ray absorption spectroscopy

Marco Grioni, Joël Mesot, François Vernay

High-resolution x-ray absorption measurements reveal a rare-earth-dependent splitting of the Ni K edge in the insulating, charge-disproportionated state of the whole RNiO3 perovskite family. The splitting is five times larger for LuNiO3 [2.5(1) eV] than fo ...

Fixed bed reactor for solid phase surface derivatization of superparamagnetic nanoparticles

Heinrich Hofmann, Jatuporn Salaklang, Alke Fink, Benedikt Steitz, Andrija Finka

The functionalization of nanoparticles is conditio sine qua non in studies of specific interaction with a biological target. Often, their biological functionality is achieved by covalent binding of bioactive molecules on a preexisting single surface coatin ...

Sensorless position estimation of linear voice-coil transducers

Yves Perriard, Jan Persson, Christian Blanc

In this paper, a method for sensorless position estimation of linear transducers at standstill is suggested. The method makes use of current pulses, which is a common sensorless starting technique for 3-phase synchronous motors. Most transducers possess ho ...
