ELECTRIC TRACTION SYSTEM FOR HIGH-SPEED GROUND TRANSPORT Russian patent published in 2004 - IPC

FIELD: transport engineering. SUBSTANCE: invention relates to high-speed ground transport with linear synchronous traction motor. Proposed traction system contains running gear on bottom of which superconducting coils of electrodynamic suspension system are arranged, and on side walls, superconducting coils of linear electric motor excitation system. Track bed is made in form of chute on vertical walls of which linear motor stator winding coils are found. Winding is made of electrically non-coupled sections. Discrete track structures of electrodynamic suspension system are located on bottom of chute. Coils of stator windings are provided with screen made of conducting nonmagnetic material at butt joint of two supplied section arranged at beginning of section of stator winding onto which running gear runs on. EFFECT: reduced energy consumption when running gear transfers from one supply section to the other owing to reduction of traction force at transfer. 2 dwg
