ABSTRACT:
Ground coils for a magnetically levitated railway include non-flux coils with an upper coil having a main-winding portion and an intermediate terminal forming a shunt-winding portion of the main-winding portion. A lower coil having a main-winding portion and an intermediate terminal forming a shunt-winding portion of the main-winding portion. The upper coil and the lower coils are arranged one above the other and are null-flux connected at null-flux connection points. A first lead terminal is connected to one null-flux connection point and a second lead terminal is connected to the intermediate terminal of the upper coil and the intermediate terminal of the lower coil for connecting to a power source and/or for interconnecting coils on left and right sides to provide guidance forces to the superconducting coils on the vehicle.
