Wire, Litz wire and winding

摘要

PPROBLEM TO BE SOLVED: To provide a litz wire improved in flexibility. PSOLUTION: The litz wire (101) has a plurality of strands (1) stranded around a core wire (10). The core wire (10) is a wire which has a flexible material of cross-sectional circular shape, and has a plurality of depressions (11) applied with a predetermined spacing in line length direction, wherein the depression (11) goes one round around the core wire (10). When the core wire is bent, the depression (11) is opened on the outside of bending, and the depression (11) is closed on inner side. Accordingly, since the core wire (10) can be bent easily, its flexibility is improved to easily use the litz wire (101) for a winding. PCOPYRIGHT: (C)2009,JPO&INPIT
