Abstract
A spirally-wound inductor having a tapered conductor. The height of the conductor increases from a smaller height near the center of the inductor to a greater height at the outer edge of the inductor. A spherically-shaped inductor and methods for manufacturing the spherically-shaped inductor. The spherically-shaped inductor has a series of coils that increase in diameter from each end toward the middle.
Claims24
An inductor, comprising:
- a conductive material spirally-wound about a center to form a plurality of coils arranged concentrically, wherein the conductive material has a height that is tapered over a portion of its length so that an inner coil has a shorter height than an outer coil.
An inductor, comprising:
- a conductive material spirally-wound about a center to form a plurality of coils arranged concentrically, wherein the conductive material has a height that varies over its length so that each coil of the plurality of coils has a greater height than its adjacent inner coil along a radius extending from the center.
An inductor, comprising:
- a conductor adapted to form a plurality of coils, wherein the plurality of coils has a generally spherical shape.
A method of manufacturing a spherical-shaped inductor, comprising:
- disposing a malleable conductor over a spherical form;
- and
- removing the spherical form from inside the spherically-shaped inductor.
A method of manufacturing a spherical-shaped inductor, comprising:
- cutting a conductive material with a pattern, wherein the pattern forms a pair of adjacent spirals in the conductive material;
- folding the conductive material at a midpoint between the pair of adjacent spirals;
- and
- displacing each center of the pair of adjacent spirals outward from the midpoint to form a plurality of coils having a spherical shape.
An inductor, comprising:
- a conductive material operable to produce a magnetic field when an electric current flows therethrough, wherein the conductive material has a height perpendicular to the magnetic field that increases with distance from a region where the magnetic field strength is greatest.
