Federal Transit AdministrationUS Transportation CollectionA propulsion prade study was conducted as part of the Colorado Maglev Project of FTA's Urban Maglev Technology Development Program to identify and evaluate prospective linear motor designs that could potentially meet the system performance requirements of the Colorado Dept. of Transportation (CDOT) Project, and be applicable to other urban maglev transit corridors. The study focused primarily on the performance of the linear induction motor (LIM) propulsion system of the Chubu HSST (CHSST) that had been selected as the baseline technology for that project. Potential near-term improvements and modifications to that propulsion system have been considered and appear feasible. This report compares the relative advantages and disadvantages of that linear induction motor and mature linear synchronous motor options for urban and suburban maglev transit systems.85
