Reactor with core gap spacers
First Claim
1. A reactor comprising:
- a pair of coils;
a pair of first iron cores disposed in parallel and respectively extending through said coils, each of said first iron cores being formed of laminated electromagnetic steel plates;
a pair of second iron cores abutted against said first iron cores, via core gap spacers, such that a square-shaped magnetic path is formed, each of said second iron cores being formed of laminated electromagnetic plates;
wherein one of said first and second pairs of iron cores constitutes an outer pair of iron cores and the other of said first and second pairs of iron cores constitutes an inner pair of iron cores, and said inner pair of iron cores is sandwiched between said outer pair of iron cores;
wherein each of said iron cores of said outer pair of iron cores is a trapezoid-shaped iron core having four contiguous straight sides, two of which are parallel to one another;
wherein for each of said trapezoid-shaped iron cores, one of said two parallel sides is a short parallel side and the other of said two parallel sides is a long parallel side which is longer than said short parallel side; and
wherein said long parallel side of each of said trapezoid-shaped iron cores is disposed between said short parallel sides of said trapezoid-shaped iron cores, respectively.

Abstract
Two sets of a combination of an iron core formed of laminated strip-shaped electromagnetic steel plates and a coil are arranged in parallel, and these are abutted via core gap spacers against two iron cores formed of laminated trapezoidal electromagnetic steel plates, so that a square-shaped magnetic path is formed. Two outside iron cores of the four iron cores are coupled and fixed with metal fittings. With such an arrangement, the coil is divided into two, with increased surface areas of the coils and therefore an improved cooling characteristic. Further, since the electromagnetic steel plates used for the iron cores can be formed into simple shapes, electromagnetic steel plates of various sizes can be easily manufactured, so that iron cores of optimum dimensions can be provided, optionally depending on the type of the reactor.
