Research on Position Detecting Method for High-speed Train with Coreless Linear Synchronous Motor

초록

One successful application of coreless LSM (Linear Synchronous Motor) is Japanese Maglev system at the Yamanashi Test Line. Position detection of Yamanashi Test Line was realized by inductive radio system which consists of onboard receiving antenna and cross inductive cable. By analyzing amplitude and phase variation of inductive electromotive force from receiving antenna, position and speed information could be determined. However, coreless LSM is proposed for wheel-on-rail system in this paper not for suspension system. We are going to introduce a novel SM (Superconducting Magnet) coreless LSM, which will provide propulsion force for wheel-on-rail high speed train. Inductive cross-loop cable could also be applied for this proposed system, but considerations should be taken due to effects of tracks and complicated electromagnetic field.
