Abstract
The magnetic core of an inductive device is formed of a plurality of wires that extend through the inductive device, and beyond the electric winding. The ends of the wires are formed around the electric winding, meet, and are connected together enveloping the magnetic core and windings forming a complete magnetic circuit. The inductive device may be a transformer with two or more windings, a choke coil with only one winding, or other inductive device. The electric windings may be wound directly onto the wire magnetic core, or may be formed separately and then placed on the magnetic core. A mounting post or the like may be bound into the core and used as a mount for the inductive device; and, cooling tubes and/or large rods for support may be incorporated into the core.
Claims29
An inductive device comprising:
- a magnetic core including a portion of a plurality of wires;
- and
- at least one electric winding extending around said magnetic core,
- wherein each of said plurality of wires substantially encircles said at least one electric winding, and wherein said plurality of wires include wires of different diameters arranged to increase the density of said magnetic core.
A method for making an inductive device, comprising:
- providing a magnetic core including a portion of a plurality of wires, the plurality of wires including wires of different diameters arranged to increase the density of the magnetic core;
- winding at least one electric winding around the magnetic core;
- and
- configuring each of the plurality of wires so as to substantially encircle the at least one electric winding.
An inductive device comprising:
- a magnetic core including a portion of a plurality of wires;
- and
- at least one electric winding extending around said magnetic core,
- wherein each of said plurality of wires substantially encircles said at least one electric winding, and wherein said plurality of wires include wires of different cross-sectional areas arranged to increase the density of said magnetic core.
