Abstract: A reactor according to an embodiment of the present disclosure includes a reactor main body including cores and coils wound on the cores; and a base having a polygonal shape extending outside the reactor main body, configured to support the reactor main body. In at least two sides that are not opposite each other, of a plurality of sides of the base, a plurality of notches are formed inwardly from each of the sides, so that axes of fasteners to temporarily secure the base to an installation target object pass through the notches.

Abstract: A core body of a reactor include an outer peripheral iron core, at least three iron cores arranged in contact with or coupled to an inner surface of the outer peripheral iron core, and at least three coils wound onto the at least three iron cores. Gaps, which can be magnetically coupled, are formed between the at least three iron cores. The reactor further includes a protection part which at least partially protects projection portions of the at least three coils which project from at least one end surface of the core body.

Abstract: A reactor includes a core body having at least three iron cores composed of a plurality of stacked magnetic plates and an end plate and a pedestal which are connected to the core body so as to interpose the core body therebetween. Gaps are formed between the at least three iron cores, through which magnetic connection can be established. An unevenness absorbing member is arranged at least one of a region between an end plate and the core body and a region between the core body and a pedestal, for absorbing unevenness in heights of the at least three iron cores in the axial direction of the core body.

Abstract: A reactor includes a core body having at least three iron cores, an end plate and a pedestal fastened to the core body so as to interpose the core body therebetween, and a plurality of shaft parts which support the core body between the end plate and the pedestal in the vicinity of an outer edge of the core body. Gaps, which can be magnetically coupled, are formed between the at least three iron cores. At least one of the plurality of shaft parts is used as a ground wiring terminal on an upper surface of the end plate.
