BOBBIN FOR RACETRACK-TYPE SUPERCONDUCTOR FIELD COIL

摘要

The present invention provides a bobbin for a superconductive field coil in the shape of a racetrack. According to an embodiment of the present invention, the bobbin around which the superconductive field coil in the shape of a racetrack is wound includes: a straight winding transformation part which includes a transformed area formed to be convexly extended in two directions and makes the superconductive field coil in the shape of a racetrack be wound in the curved shape; and a curved winding maintaining part which makes the superconductive field coil in the shape of a racetrack be wound with winding tension higher than that of the superconductive field coil in the shape of a racetrack wound around the straight winding transformation part.
