Document Type and Number:
WIPO Patent Application WO/2019/235368
Kind Code:
A1
Abstract:
This reactor is equipped with: a coil which has a winding section; a magnetic core which has an inside core part and an outside core part; and a holding member for holding the outside core part and the end surface of the winding section in the axial direction. Therein, the holding member is a frame-shaped body having a through-hole therein through which the end section of the inside core part in the axial direction is inserted. The inside core part or the outside core part is a hybrid core configured from a compressed powder molded article and a resin core which is molded around the outer periphery thereof, while the other is a hybrid core or a resin core. The resin core of the inside core part and the resin core of the outside core part are connected to one another via the through-hole in the holding member, and the magnetic core comprises a single seamless body. The compressed powder molded article is a magnetic body obtained by compression-molding a starting material powder which contains a soft magnetic powder. The resin core is a magnetic body obtained by molding a composite material of a soft magnetic powder and a resin.
