Abstract:
A method for making an electromagnetic coil assembly, comprising:providing a flat strip comprising a bendable electrically conductive metal, the strip having opposite planar surfaces at least one of which is covered by a dielectric material, the strip having opposite first and second end portions; bending the first end portion of the strip about a bend axis that is substantially perpendicular to the planar surfaces of the strip through an angle of substantially 90Â°; bending the second end portion of the strip about a bend axis that is substantially perpendicular to the planar surfaces of the strip through an angle of substantially 90Â°; winding the strip about an inner hub having a central longitudinal axis such that the bent first and second end portions of the strip extend generally parallel to the central longitudinal axis of the inner hub, so as to form a coil on the inner hub with the bent first and second end portions of the strip forming inner and outer coil leads that extend axially away from the coil; and connecting an electrical conductor to each of the coil leads.
