ABSTRACT:
A magnetic core is disclosed comprising a plurality of stacked laminations of metallic glassy ribbon. The laminations are arranged in groups of at least two laminations, with the laminations of each group being arranged to compensate for cross-sectional non-uniformity present in laminations comprising each group, thereby producing groups having substantially parallel top and bottom planar surfaces. The groups are then stacked in partially overlapping relationship to define a closed loop magnetic core. Cores formed from such groups of laminations exhibit reduced core losses as compared to prior art stacked cores.
