ASSEMBLED WIRE, METHOD OF MANUFACTURING ASSEMBLED WIRE AND SEGMENT COIL

WIPO Patent Application WO/2019/176254

A1

Provided is an assembled wire having a substantially rectangular cross section, and is formed by assembling a plurality of strands 7. Each strand 7 has a conductor portion 11 and a strand insulating layer 13 covering the conductor portion 11. At least a part of the assembled plurality of strands 7 in the longitudinal direction is covered with an outer insulating layer. The strand 7 is formed as follows. First, the strand insulating layer 13 is coated on the outer periphery of the conductor portion 11. At this time, a large number of voids 8 are formed in a resin 12 constituting the strand insulating layer 13. From this state, the strand 7 is formed, for example, by collapsing the strand insulating layer 13 by heating and pressurizing. At this time, it is possible to uniformly collapse the strand insulating layer 13 by crushing the internal voids 8. Therefore, the voids 8 in the strand 7 are crushed and flattened in the thickness direction of the strand insulating layer 13 over the entire periphery.
