Abstract:
A electromagnetic device comprising:one or more electrical conductors shaped into windings of an electromagnetic device in a substantially cylindrical configuration, wherein each adjacent conductor of said windings is electrically insulated from each other adjacent conductor; a cylindrical body comprising a plurality of radially compacted powdered magnetic material particles bound together due to compaction, surrounding and solidly enclosing said one or more conductors therein, said cylindrical body being electrically insulated from said one or more conductors, said cylindrical body circumscribed by a continuous substantially cylindrical interior surface and a continuous substantially cylindrical exterior surface substantially concentric therewith, a first axial end surface connected between one edge of said continuous substantially cylindrical interior surface and one edge of said continuous substantially cylindrical exterior surface, and a second axial end surface connected between the other edge of said continuous substantially cylindrical interior surface and the other edge of said continuous substantially cylindrical exterior surface, said second axial end surface being opposite to and substantially parallel to said first axial end surface, a plurality of electrical connector leads beginning outside said cylindrical body and passing through at least one of the surfaces of said cylindrical body, said plurality of electrical connector leads electrically connected to said one or more conductors.
