Patent ID: 7271695

Claim:
An electromagnetic apparatus comprising: (a) a magnetic material arranged in a core structure; said core structure establishing a first flux path set and a second flux path set; said first flux path set comprising a first middle flux path generally oriented about a first axis and two first side flux paths generally parallel with said first axis; said second flux path set comprising a second middle flux path generally oriented about a second axis and two second side flux paths generally parallel with said second axis; said second axis being generally perpendicular with said first axis; said first flux path set and said second flux path set cooperating to establish a plurality of open spaces; each respective open space of said plurality of open spaces being bounded by portions of two respective flux paths from each of said first flux path set and said second flux path set; and (b) a plurality of windings for conducting electrical current about said magnetic core structure; said plurality of windings being wound around one axis of said first axis and said second axis on both sides of the other axis of said first axis and said second axis.
