Abstract

PURPOSE: To reduce the cross section of an insert iron core and enable compact design by using a high-quality iron core as an insert magnet leg for coils and molding the other core portion of a mixture of a binder resin and a magnetic material consisting mainly of iron powder.
CONSTITUTION: An insert magnet leg 3 for coils 2 is made of a high-quality iron core, and a mold iron core 1 is formed of a mixture of a binder resin and a mgnetic material consisting mainly of iron powder. The high-quality iron core consists of silicon steel plates or the like. The magnetic material consists of iron powder mixed with or without proper amounts of powders of cobalt, nickel, and aluminum. The binder resin consists of epoxy resin, polyester resin, phenol resin, or the like. Split primary and secondary coils are easily aligned with the leg 3 as a shaft, the cross section of the insert core is reduced, and the coils and the transformer are made compact.
