Abstract
Abstract An inductive reactor is described comprising an outer core body having a plurality of planar laminations of low magnetic reluctance material and a center leg spanning the hollow interior of the core body. A winding surrounds the center leg. The center leg is comprised of a plurality of parallel elongated sections extending along the length of the outer body and spaced from each other to form parallel nonmagnetic planar gaps. Each section is comprised of a plurality of elongated parallel planar strips of low magnetic reluctance material perpendicular to the planes of the laminations and the planes of the gaps.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
145 words
An inductive reactor, comprising, an outer body of low magnetic reluctance material forming an elongated hollow structure, said outer body being comprised of a plurality of planar laminations arranged parallel with each other, a center leg spanning the hollow interior of said outer body and extending along the length thereof, and a winding on said center leg, said center leg being comprised of a plurality of elongated parallel sections extending along the length of said outer body, said sections being in the shape of rectangular hexahedrons and being spaced from each other to form a series of nonmagnetic planar gaps, said sections each being comprised of a plurality of elongated parallel planar strips of low magnetic reluctance material, each of said strips extending the full length of said outer body and being perpendicular to the planes of said laminations and the planes of said gaps.
Claim 2
Dependent Claim
145 words
An inductive reactor, comprising, an outer body of low magnetic reluctance material forming an elongated hollow structure, said outer body being comprised of a plurality of planar laminations arranged parallel with each other, a center leg spanning the hollow interior of said outer body and extending along the length thereof, and a winding on said center leg, said center leg being comprised of a plurality of elongated parallel sections extending along the length of said outer body, said sections being in the shape of rectangular hexahedrons and being spaced from each other to form a series of nonmagnetic planar gaps, said sections each being comprised of a plurality of elongated parallel planar strips of low magnetic reluctance material, each of said strips extending the full length of said outer body and being perpendicular to the planes of said laminations and the planes of said gaps.
Claim 3
Dependent Claim
18 words
An inductive reactor in accordance with claim 1 wherein each of said laminations comprises a generally rectangular frame.
Claim 4
Dependent Claim
49 words
An inductive reactor according to claim 2 wherein each frame includes a pair of projections aligned with each other and projecting inwardly from opposite sides of said frame, and wherein a nonmagnetic support structure is provided supporting said center leg, said support structure engaging said projections on said frames.
Claim 5
Dependent Claim
36 words
An inductive reactor according to claim 3 wherein said support structure comprises a pair of parallel walls and a plurality of shelves extending perpendicular to said walls for separating said elongate sections of said center leg.
