Electrical winding and method of making the same

摘要

A generally rectangular electrical winding 30 is formed from a continuous length of laminated foil ribbon with each turn being generally planar and four-sided. At each corner of the turn joining a pair of adjacent orthogonally related generally straight sides, the ribbon is creased and rises out of the plane defined by the adjacent sides so that a continuous edge 38 of the ribbon defines an interior opening of the winding. Each successive turn overlies the preceding turn.
