Title:
GROUND COIL DEVICE FOR MAGNETIC LEVITATION RAILWAY AND METHOD OF PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2008/020626
Kind Code:
A1
Abstract:
A ground coil device for a magnetic levitation railway, in which a bush (3) for fixation having an installation hole (3a), which is in parallel with the center axis of an annularly wound coil conductor, is placed inside the annular shape of the coil conductor and the coil conductor and the bush (3) are integrally formed by using a thermoplastic resin, thus forming an outer cover (4) for the coil conductor. The thickness of the thermoplastic resin of a connection portion for connecting between the bush (3) and the coil conductor is set less than the thickness of the coil conductor, and reinforcement ribs (4b-4i) integrating the connection section and the outer cover (4) are formed with the thermoplastic resin in a radial pattern laid from the bush (3) side to the coil conductor side.
