Abstract:The overall objective of this program is to develop magnetic levitation technology that is a cost effective, reliable, and environmentally friendly option for urban mass transportation in the United States. Maglev is a revolutionary approach in which trains are supported by magnetic forces without any wheels contacting the rail surfaces. The Urban Maglev Program is sponsored by the Federal Transit Administration and funded under the Transportation Equity Act for the 21st Century (TEA-21). An innovative approach for Urban Maglev has emerged that involves an entirely passive, permanent magnet levitation system with an efficient linear synchronous motor powering the guideway to provide propulsion. The system is unique in that operates with a large air gap of 25 mm with no feedback control required for stable levitation; furthermore, the packaging of the levitation magnets allows the vehicle to accommodate a very tight turn radius of 18.3 m. The studies show that the General Atomics Urban Maglev system offers many attractive benefits, including very quiet operation, the ability to operate in challenging terrain with steep grades and tight turns, all-weather operation, low maintenance, rapid acceleration, and the potential for high speed.
