MagLev Cobra project: Superconducting levitation for public transportation

Abstract

This work presents the main properties of the MagLev Cobra Project, currently in development at Federal University of Rio de Janeiro. One presents the basics on magnetic levitation technique, highlighting the advantages of the proposed method faced to wheel/rail systems and light rail vehicles. The history of the project is presented. Technical details, such as the line of permanent magnets, the cryostats with superconductors, the linear traction motor, are discussed. Finalizing, the sustainability of the project is highlighted, considering its economic, social and environmental impacts.
