Title: Linear motor drive for train - with drive force controlled by speed of on-board pole wheel
Inventor: VOIGT HANS DIPL PHYS DR
IPC: B60L15/00
Filed: 1974-05-15
Abstract: The track forms the active part of the linear motor and is fed with a fixed frequency magnetic field, which has a set propagation speed along the rail.
