Abstract
The U.S. DOT Federal Transit Administration (FTA) launched an Urban Maglev initiative in 1999 in order to create designs suitable for urban transit. MagneMotion, EarthTech, TPI Composites and others formed a team and, with cost sharing support from FTA, have developed an urban maglev system called M3 that is suitable for a Maglev People Mover (MPM). The M3 Maglev People Mover was designed with a system approach focused on providing cost effective, fast, safe and environmentally friendly travel in an urban environment. Features of M3 are: (1) Small, lightweight vehicles operate at speeds up to 60 m/s (134 mph) with accelerations up to 0.2 g, (2) a guideway-based control system with Linear Synchronous Motor (LSM) propulsion allows short headway for capacities to 12000 pphpd, (3) ElectroMagnetic Suspension (EMS) provides lift at zero speed eliminating the need for wheels, (4) permanent magnets provide key magnetic forces with high efficiency and a magnetic gap of 20 mm, and (5) lightweight guideways provide excellent ride quality at minimum cost. This paper discusses the M3 suspension, propulsion and guideway designs and is a companion to another paper which discusses vehicle design and system control.
