ABSTRACT:
A primary coil assembly for a superconducting linear induction motor is provided which is arranged opposite to a secondary conductor for exerting a relative thrust on the secondary conductor when energized. The primary coil assembly comprises a plurality of coil units, each including a nonmagnetic and nonconductive bobbin, an alternating-current superconducting wire wound around the bobbin, and nonmagnetic and nonconductive spacers interposed between adjacent turns of the superconducting wire being adjacent to each other in an outward direction with respect to the axis of the bobbin or adjacent to each other in the width direction of the bobbin, for providing a clearance therebetween. The coil units have substantially identical structure and shape and are spaced at a predetermined distance from each other.
