Superparamagnetic anisotropic elastomer connectors exhibiting reversible magneto-piezoresistivity

Thomas Maeder

An anisotropic magnetorheological composite formed by dispersions of silver-covered magnetite microparticles (Fe3O4@Ag) in polydimethylsiloxane (PDMS) displaying electrical conduction only in one preferred direction is presented. A set-up for applying and ...

Magnetic Model of the CERN Proton Synchrotron

Mariusz Juchno

In this thesis, we present development of the first magnetic model of the main Proton Synchrotron magnets. The operation of the machine and conducting research on increasing its performance require a significant amount of the magnetic field data for the op ...

Electromagnetic Analysis and Validation of an Ironless Inductive Position Sensor

Yves Perriard, Alessandro Danisi, Alessandro Masi

The ironless inductive position sensor is a linear position sensing structure, which exhibits intrinsic immunity to external magnetic fields since it is characterized by air-cored windings. This new solution may be of major interest for applications where ...

Experimental validation of a coupled magneto-thermal model for a flat-parallel-plate active magnetic regenerator

Didier Albert Simon Vuarnoz

In this study, a flat-parallel-plate active magnetic regenerator made of gadolinium is investigated. The coupling of a one-dimensional thermal model with a two-dimensional magnetic model is presented. The thermal model takes into consideration the magnetoc ...

Development of an identification method of pressure anisotropy based on equilibrium analysis and magnetics

Wilfred Anthony Cooper

We evaluate the fluxes measured by the magnetic flux loops installed in LHD by using a three dimensional MHD equilibrium analysis code, ANIMEC, which enable us to directly determine the calibration function between the anisotropic pressure and the measured ...

Modeling of Inductive Contactless Energy Transfer Systems

Pascal Meyer

In the domain of electronic devices and especially desktop peripherals, there is an industrial trend which consists in removing the cables that pollute our domestic and professional environments. In this sense, wireless communication protocols are already ...

A Practical Solution to Mitigate Vibrations in Industrial PM Motors Having Concentric Windings

Dimitri Torregrossa, Luc Burdet, Christophe Espanet

Industry applications involving torque brushless dc motors require high efficiency over a large speed range. In order to achieve such specifications, flux weakening is necessary, which could lead to relative high electromagnetically induced vibrations and ...
