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.
Claims12
A reactor comprising a core body including at least three iron cores composed of a plurality of stacked magnetic plates, wherein
- the core body includes an outer peripheral iron core composed of a plurality of outer peripheral iron core portions,
- the at least three iron cores are connected to the plurality of outer peripheral iron core portions,
- coils are wound around the at least three iron cores, and
- gaps are formed between one of the at least three iron cores and another iron core adjacent thereto, through which gaps the iron cores are magnetically connectable, the reactor further comprising:
- an end plate and a pedestal which are coupled to the core body so as to interpose the core body therebetween, and
- an unevenness absorbing member arranged in at least one of a region between the end plate and the at least three iron cores of the core body and a region between the at least three iron cores of the core body and the pedestal, for absorbing unevenness in heights of the at least three iron cores in an axial direction of the core body.
