A winding for a transformer or coil includes a ribbon electrical conductor and at least one ribbon insulation material layer fitted thereto or applied as ribbon material thereto. The conductor and the insulating material layer are wound to form turns around a winding core along a winding axis. The individual turns of the winding have a predetermined winding angle with respect to the winding axis. A number of turns are located axially alongside one another form one layer, and at least two radially adjacent layers of turns are provided. A first layer of turns is radially adjacent to a second layer produced by changing the winding direction by folding the electrical conductor and the insulating material layer. The total angle, which is produced by the folding, between the longitudinal direction of the ribbon insulating material in the first layer and the corresponding direction of the second layer corresponds to twice the winding angle.

Winding for a transformer or a coil and method for producing the winding

A presently-preferred process for manufacturing a magnetic-induction device comprises stacking a plurality of laminae to form a winding leg, a first yoke, and a second yoke, and fixedly coupling a first end of the winding leg to the first yoke. The presently-preferred process also comprises winding a length of insulated conductive cabling on the winding leg to form a phase winding after fixedly coupling the winding leg to the first yoke, and fixedly coupling a second end of the winding leg to the second yoke after forming the phase winding. Alternatively, the length of insulated conductive cabling may be wound on the winding leg after the second end of the winding leg has been fixedly coupled to the second yoke.
