Traction2020, Ecoptine
Virginie Kluyskens

The aim of the project "TRACTION 2020 - Development of a high efficiency and high reliability railway traction" is the reduction of the consumption of electrical energy in railway traction. The hope is to improve by about 5% the efficiency of the traction chain, while also keeping in mind criteria like reliability, price and life cycle cost. In this context, our research concerns more specifically two components of the traction chain: (i) the electric motor converting the electrical energy into mechanical energy: a synchronous reluctance motor and (ii) the magnetic gear inserted between the motor and the axle of the boogie. Our objective is to propose the optimal electromagnetic design for these two components.

The aim of the project "ECOPTINE - Energy aCcumulation for Optimization of electrical Traction INfrastructure Efficiency" is to ensure an optimal (and renewable) source of energy for rail traction, thus allowing a gain in terms of cost and performance. It aims to design an energy accumulation and storage solution (via a flywheel) as well as a system for connection to the energy distribution network. In this context our research concerns the passive magnetic bearing system of the flywheel.


Development of self-bearing machines with hybrid magnetic suspension and PCB windings for cutting-edge applications
Joachim Van Verdeghem

The aim of this project is to propose and validate the first self-bearing electric machine that requires no sensors, power electronics and control specifically dedicated to the rotor magnetic levitation while operating both at low and high speeds.
