Title: Coil apparatus for a linear-motor railway system

Abstract: A coil apparatus for a linear-motor railway system comprises six superconductive coils mounted on a bogie of a vehicle at a predetermined pitch such that N and S poles are alternately formed; ground coils disposed on either side wall of a guide, each of the ground coils providing propulsion, levitation, and guide functions, and each set of three ground coils corresponding to a pair of adjacent superconductive coils that form N and S poles; and a feeder circuit connected to the ground coils. The coil apparatus can decrease the number of ground coils in order to decrease man-hour required for installation, and to facilitate inspection and maintenance of contact points through reduction in the number of the connection points.
