Magnetic levitation transportation system ground coil unit and manufacturing method thereof

摘要

In a magnetic levitation transportation system ground coil unit in which inside an annular coil conductor that is annularly wound, a mounting bush 3 including such a mounting hole 3a as to be parallel to a central axis of the coil conductor is disposed, and the coil conductor and the bush 3 are integrally molded using a thermoplastic resin to form a casing 4 of the coil conductor, thickness of the thermoplastic resin of a connection part that provides a connection between the bush 3 and the coil conductor is made smaller than thickness of the coil conductor, and a plurality of reinforcing ribs 4b to 4i that are formed using the thermoplastic resin are provided radially from the bush 3 side toward the coil conductor side to be integral with the connection part and the casing 4.
