Patent ID: 8686824

Claim:
For an electromagnetic device, a magnetic core formed from steel laminations, comprising a plurality of core elements, comprising at least two legs, at least two yokes, the yokes being oriented substantially quadrature to the legs, such that abutting core elements are in substantially quadrature relation, a plurality of flux deflection zones defined in regions where flux flows from one core element to an abutting core element, the legs being formed from alternating interleaved laminate layers, at least one of the layers being composed of grain-oriented steel, and the remaining layers of the core elements being composed of non-grain-oriented steel, such that a plurality of flux deflection zones are each composed substantially of non- grain-oriented steel layers from a leg extending substantially over an entire region where the flux changes direction in the core interleaved with non-grain-oriented steel layers from a yoke extending substantially over the entire region where the flux changes direction in the core, the plurality of flux deflection zones thereby being composed substantially of non-grain-oriented steel, whereby flux flowing in a direction of a grain orientation in the at least one layer composed of grain-oriented steel changes direction to flow through the abutting core element in the flux deflection zone composed of non-grain-oriented steel.
