The technology of electric propulsion as applied to tracked levitated, high speed ground transportation vehicles is discussed. A brief review of the linear induction motor and its associated power conditioning is presented. The electric power and propulsion systems of selected vehicles currently under development and test by the U.S. Department of Transportation are discussed. The electric propulsion characteristics of several vehicles currently under development by the U.S. Department of Transportation that utilize linear induction motors are given. The linear induction motor research vehicle (LIMRV) is a 250 mph research vehicle whose prime mission is linear motor research. The tracked levitated research vehicle (TLRV) is a 300 mph, air cushion levitated vehicle whose mission is research in high speed propulsion and in track levitation. The prototype tracked air cushion vehicle (PTACV) is a 150 mph, air cushion levitated, 60 passenger prototype vehicle for intra-urban application. The LIMRV uses an on-board power source consisting of a gas-turbine-driven alternator providing variable-frequency power to the LIM. The TLRV and the PTACV both pick up three-phase electric power from the wayside. The LIMRV and TLRV use power conditioners rated at approximately 1 mph/Hz, the PTACV power conditioner provides variable- voltage fixed-frequency power control.
