WOUND IRON CORE

摘要

PROBLEM TO BE SOLVED: To provide a wound iron core capable of suppressing a temperature rise at a corner part and a peripheral part of the corner part.SOLUTION: A wound iron core 10 includes an iron core body part 11 about which a plurality of iron core materials are wound. The iron core body part 11 is divided into a plurality of iron core material blocks 11A-11D along a lamination direction of the iron core materials, and the iron core material blocks 11A-11D have bending angles at a corner part 13, the bending angles being different from each other.
