SOFT MAGNETIC FERRITE RESIN COMPOSITION, SOFT MAGNETIC FERRITE RESIN COMPOSITION MOLDED BODY, AND POWER TRANSMISSION DEVICE FOR NON-CONTACT POWER SUPPLY SYSTEM

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/cm³ 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.
