Synchronlage-Ermittlungs-System für einen Zug mit linearem Synchronmotor

摘要

A synchronous position correction system for a self-controlled linear synchronous motor train includes a position detector for detecting a positional relationship between a propulsion winding provided on a track and a field pole provided on the train which is formed by a plurality of cars. A synchronous operation of the formed train is performed at a phase which is obtained by correcting a phase detected by the position detector on the basis of a difference between an average phase of the whole of the formed train and the phase detected by the position detector, at a phase which is obtained by correcting the phase detected by the position detector on the basis of a difference between the phase of a speed electromotive force of the whole of the formed train and the phase detected by the position detector, or at a phase which is detected by the position detector in conjunction with the position of a central car of the formed train. As a result, a propulsive force is prevented from being deteriorated due to a phase shift caused by an error in train length and it is possible to operate the formed train at an optimal phase at which the best efficiency is obtained.
