Claims

[Scope of Claim for Utility Model Registration] (1) An iron core comprising a main leg formed by alternately stacking core packets and void forming materials, and two yokes arranged at both ends of the main leg in the axial direction. , a reactor including a winding wound around the main leg, in which rectangular magnetic plates are radially laminated to cover at least a part of the axial end face of the main leg and a portion extending outward from the end face. An iron-core reactor characterized in that an additional packet is provided between the yoke and the winding. (2) In the utility model registration claim described in paragraph 1, the central part of the additional packet is also used as the core packet, and the dual-purpose part and the surface of the additional packet other than the dual-purpose part on the side opposite to the yoke are on the same plane. An iron core reactor characterized by being placed on top. (3) In the utility model registration claims described in either paragraph 1 or 2, the additional packet is a yoke or a yoke extending outward from the end surface in the axial direction of the main landing gear. An iron core reactor characterized in that a magnetic material is arranged except for the part facing the extension part of the reactor.
