    摘要: When an outer core that is to be mounted on a reactor is seen in plan, the outer core is a compact that has a plan-view shape in which a side of the outer core that is opposite to a facing side of the outer core, which faces the inner cores, has a smaller dimension in a width direction, which is parallel to a facing surface, than the facing side of the outer core. A method of manufacturing such an outer core includes a preparing step and a compacting step. In the preparing step, coated soft magnetic powder including multiple coated soft magnetic particles formed by coating soft magnetic particles with insulating coated films is prepared as raw-material powder of the outer core. In the compacting step, a compacting space 31, which is defined by a pillar-like lower punch 12 and a tubular die 10A, is filled with the coated soft magnetic powder and then the coated soft magnetic powder in the compacting space 31 is compacted by the lower punch 12 and a pillar-like upper punch 11, the lower punch 12 and the tubular die 10A being movable relative to each other. In the compacting step, the facing surface of the outer core is pressed by the upper punch 11.

    摘要: Provided are a green compact from which a low-loss core can be formed, a method of manufacturing the green compact, and a core for a reactor using the green compact. Parts of outer circumferential surfaces of green compacts 41 and 42 are molded with an inner peripheral surface of a through hole 10hA of a die 10A, and the other parts are molded with an outer circumferential surface of a core rod 13A that is inserted and disposed in the through hole 10hA. A raw-material powder P, which is a coated soft magnetic powder, is fed into compacting spaces 31 and 32 and pressurized by using a lower punch 12 (first punch) and an upper punch 11 (second punch). Then, the green compacts 41 and 42 are removed from the compacting spaces 31 and 32 by moving the die 10A with respect to the green compacts 41 and 42 without moving the core rod 13A with respect to the green compacts 41 and 42. An area that is on the outer circumferential surface of each of the green compacts 41 and 42 and that is molded with the core rod 13A does not rub against the core rod 13A, and thus a complete insulating layer is maintained in the area. Therefore, a core using the green compact 41 or 42 can reduce eddy current loss.
