Initially, linear motors have been particularly dedicated to transportation systems. Nowadays, linear motors are meant to replace a system using a rotating motor and a transmission to realize a linear movement. With linear motors the performances increase ...
High speed rotation of small rotors is needed more and more in many industrial applications. Classical examples are compact devices like scanners, gyroscopes, centrifuge units and so on. The key to achieve high rotating speeds is to have contactless bearin ...
Worldwide high speed Maglev (> 400km/h) developments refer to Maglev such as the Japanese JR-Maglev MLX, the German Transrapid and the USA Inductrack Maglev. Other world projects exist such as the Japan HSST (< 300km/h) and the China HTC. The JR-Maglev, th ...
This Master project concerns the electrostatic motors and focus essentially on the transverse force producing the torque. A study of this force is done with a glass sample and an electret sample under different input parameters such as the applied voltage, ...
Using 3D finite element method (FEM) modelling, the present work investigates the coupling effect between two finite superconductors through a resistive matrix. This effect, related to the finite length of the conductors, is typically three-dimensional and ...
Electromagnetic levitated and guided systems are commonly used in the field of people transport vehicles, tool machines, frictionless bearings and conveyor systems. In the case of low speed people transport vehicles, the electromagnetic levitation offers t ...
This paper addresses the design and optimization of a small-sized linear electrodynamic actuator. This actuator is aimed to be inserted under a computer key in order to produce a force feedback to the user. Replacing the current rubber dome supporting the ...
n large cities, due to expensive land price, high-rise buildings are built, in which the space dedicated to the elevators is considerable and reduces the rented surfaces. To decrease these lost surfaces, a Multi Mobile System is proposed. It consists of se ...

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 ...
