Leakage Flux Modelling in Magnetic Fluids Test Bench

Yves Perriard, Yoan René Cyrille Civet, Cécile Gisèle Aimée Jeannine Cuchet, Christophe Espanet

The proposed paper discusses a new methodology to monitor the B-H curve of magnetic fluids, which have low relative permeability. The set-up consists of a magnetic circuit which encloses a sample. A first coil allows creating a magnetic field into the samp ...

SWISSMETRO - Polarized Linear Motor Combined With Levitation Actuators

Marcel Jufer, Patric Hagmann, Christophe Espanet

SWISSMETRO is a MAGLEV Project, designed for a speed up to 500 km/h in two tunnels under partial vacuum. The authors investigate new possibilities to combine the propulsion and levitation. Polarized inductors for the levitation are studied, implying a pola ...
