COMPOSITION DE RÉSINE ET FERRITE MAGNÉTIQUE DOUCE, CORPS MOULÉ EN COMPOSITION DE RÉSINE ET FERRITE MAGNÉTIQUE DOUCE, ET DISPOSITIF DE TRANSMISSION D'ÉNERGIE POUR SYSTÈME D'ALIMENTATION ÉLECTRIQUE SANS CONTACT

摘要

An object of the present invention is to provide a power transmission device for a non-contact power feeder system which has high power transmission efficiency and high impact resistance. The above object of the present invention can be achieved by a soft magnetic ferrite resin composition molded product comprising a filler and a binder, in which the filler comprises soft magnetic ferrite particles having an average particle diameter of 5 to 35 µm, the binder comprises at least one material selected from the group consisting of a thermoplastic resin and a soft polyolefin resin, and the soft magnetic ferrite resin composition molded product has a molding density of 3.2 to 4.7 g/cm 3 and a magnetic permeability of 5 to 15, and a power transmission device for a non-contact power feeder system which comprises the above soft magnetic ferrite resin composition molded product.
