SWISSMETRO Combined Propulsion With Levitation And Guidance
Swissmetro is a MAGLEV Project between the main cities of Switzerland, designed for a speed up to 500 [km/h] in two tunnels under partial vacuum. Two propulsion variants are considered: the short stators of the linear homopolar motors are fixed with the tunnel tracks; the stator of the motors is on board of the vehicles. The levitation, the guidance and the transfer of energy are independent. T...
متن کاملSWISSMETRO Polarized Linear Motor Combined With Levitation Actuators
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 polarized (permanent magnet) synchronous linear motor. The thermal behavior is investigated using a numerical platform of the complete vehicle-tu...
متن کاملMulti-level Thrust Ripples Minimization of Linear Flux Switching Motors With Segmented Secondary by Combined Genetic Algorithm and Response Surface Methodology
Linear flux switching motors with simple passive segmented secondary, referred as Segmented Secondary Linear Flux Switching Motors (SSLFSMs), have low cost secondary and therefore are applicable to transportation systems like Maglev. However, it is shown that the SSLFSMs suffer from high thrust ripples. In this paper, minimizing SSLFSM thrust ripples besides maximizing its developed thrust are ...
