Total Claims: 9
Claim 1
Independent Claim
148 words
A transformer comprisng: a magnetic core formed of a stacked array of laminations defining a magnetic flux path including first and second leg portions and first and second yoke portions; a plurality of conductive coils encircling at least a part of said first leg portion; a plurality of additional leg laminations, interleaved between selected ones of said stacked array laminations in at least a part of said second leg portion; and a plurality of yoke spacer laminations interleaved between selected ones of said stacked array of laminations in direct correspondence to said interleaving of said additional leg laminations, to minimize voids created between said core laminations by said interleaving of said additional leg laminations, said yoke spacer laminations having a dimension orthogonal to said second leg portion which varies between a maximum at the approximate center of said stacked array and minima at the extremes of said stack.
Claim 2
Dependent Claim
148 words
A transformer comprisng: a magnetic core formed of a stacked array of laminations defining a magnetic flux path including first and second leg portions and first and second yoke portions; a plurality of conductive coils encircling at least a part of said first leg portion; a plurality of additional leg laminations, interleaved between selected ones of said stacked array laminations in at least a part of said second leg portion; and a plurality of yoke spacer laminations interleaved between selected ones of said stacked array of laminations in direct correspondence to said interleaving of said additional leg laminations, to minimize voids created between said core laminations by said interleaving of said additional leg laminations, said yoke spacer laminations having a dimension orthogonal to said second leg portion which varies between a maximum at the approximate center of said stacked array and minima at the extremes of said stack.
Claim 3
Dependent Claim
48 words
A transformer as set forth in claim 1 wherein said yoke spacer laminations each define a first edge adjacent said additional leg lamination and a second edge most remote from said additional leg lamination and wherein said second edges of said yoke spacers in each layer are colinear.
Claim 4
Dependent Claim
29 words
A transformer as set forth in claim 2 wherein said lamination of said core, said additional leg laminations and said yoke spacer laminations are all fabricated of grain-oriented steel.
Claim 5
Dependent Claim
16 words
A transformer as set forth in claim 3 wherein said transformer is a shell form transformer.
Claim 6
Dependent Claim
16 words
A transformer as set forth in claim 3 wherein said transformer is a core form transformer.
Claim 7
Dependent Claim
112 words
In a magnetic core in which a plurality of laminations are combined in a stacked array to form a magnetic flux path including first and second leg portions together with first and second yoke portions and in which the cross-sectional area of said second leg portion is increased relative to said first leg portion by interleaving a plurality of additional leg laminations between selected ones of said laminations, the improvement comprising: a plurality of yoke spacer laminations in said stacked array having a dimension orthogonal to said second leg portion which varies between a maximum at the approximate center of said stacked array and minima at the ends of said stacked array.
Claim 8
Dependent Claim
112 words
In a magnetic core in which a plurality of laminations are combined in a stacked array to form a magnetic flux path including first and second leg portions together with first and second yoke portions and in which the cross-sectional area of said second leg portion is increased relative to said first leg portion by interleaving a plurality of additional leg laminations between selected ones of said laminations, the improvement comprising: a plurality of yoke spacer laminations in said stacked array having a dimension orthogonal to said second leg portion which varies between a maximum at the approximate center of said stacked array and minima at the ends of said stacked array.
Claim 9
Dependent Claim
28 words
A magnetic core as set forth in claim 6 wherein said plurality of lamination, said additional leg lamination, and said yoke spacer laminations are formed of grain-oriented steel.
