Patent ID: 8638016

Claim:
A electromagnetic structure, comprising: a rotor assembly comprising: a circular magnetic structure comprising a magnetizable material that is printable, wherein said circular magnetic structure has opposing first and second surfaces that extend around a peripheral boundary region, said peripheral boundary region having a plurality of printed emission sources, wherein each printed emission source on said magnetizable material presents poles having opposite polarities of a first polarity and a second polarity, wherein adjacent printed emission source have alternating pole orientations such that each printed emission source having said first polarity is between two printed emission sources having said second polarity and each printed emission source having said second polarity is between two printed emission sources having said first polarity; and a rotational element for rotating said circular magnetic structure about a rotation axis that is perpendicular to said opposing first and second surfaces; and at least one stator assembly comprising: at least one core element that extends from said first surface around to said second surface to magnetically couple said poles of opposite polarities of each respective printed emission source of said plurality of printed emission sources when said rotor is rotated about said rotation axis; and at least one coil winding wound around the at least one core element.
