Abstract: Magnetic core structure of the stacked type having outer legs (11, 12), at least one inner leg (13), and top (14, 15) and bottom yokes (16, 17) formed of a plurality of stacked groups of layers of metallic laminations. The yoke and leg laminations have their ends cut diagonally to provide a closed magnetic circuit having diagonal joints between adjoining ends of the yoke and leg laminations. The length dimensions of the inner leg laminations are uniform from layer to layer within each group, while the junction of the diagonally cut ends of the inner leg laminations are offset from the centerline thereof from layer to layer in a step pattern that progresses an equal number of steps on each side of the centerline of each group of layers of inner leg laminations to be step dependent. The configuration of the outer leg laminations and the top and bottom yoke laminations are uniform from layer to layer within each group to be step independent. A method of stacking the laminations in groups is disclosed and there is also disclosed a method of making the center or inner laminations of the magnetic core structure in two parts where the width of the laminations is greater than the commercially available lamination material.
