Title:
COMPOSITE MATERIAL, REACTOR-USE CORE, AND REACTOR
Document Type and Number:
Japanese Patent JP2017017326
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide: a low-loss composite material with a high saturation magnetic flux density; a reactor-use core comprising the composite material; and a reactor including the core.SOLUTION: A composite material contains magnetic substance powder and a resin containing the powder that is dispersed therein. The magnetic substance powder contains a plurality kinds of powders made of materials differing in the relative permeability. The composite material contains non-magnetic substance powder made of at least one type of material. In a particle size distribution of mixed powder made up of the magnetic substance powder and the non-magnetic substance powder, a maximum particle size with which a peak of the non-magnetic substance powder appears is smaller than a minimum particle size with which a peak of the magnetic substance powder appears.SELECTED DRAWING: Figure 1
