Document Type and Number:
WIPO Patent Application WO/2023/067870
Kind Code:
A1
Abstract:
A coil body (32) is provided with a belt member (34) and a plurality of coils (16). The band member (34) is annularly wound along the circumferential direction so as to form a plurality of layers in the radial direction. The plurality of coils (16) have vertical portions (36), are arranged at predetermined positions in the circumferential direction and the radial direction of the band member (34), and are bound by predetermined wire bound patterns. Further, the coil body (32) is provided with a vertical-portion laminate (56) formed by laminating the vertical portions (36) in the radial direction, in a cross-section obtained by cutting the band member (34) and the plurality of coils (16) in the radial direction. In the vertical-portion laminate (56), the vertical portions (36) having different potentials in a state of being energized through the plurality of coils (16) are adjacent to each other in the radial direction.
