1. A method for forming a stator coil, the method comprising:
forming a first turn from a conductor having two or more layered parallel strands with a first part of the first turn on a first side of a folding axis and a second part of the first turn on a second side of the folding axis, the first part and the second part of the first turn interconnected with a first inversion region;
forming at least one additional turn from the conductor coupled to the first turn and including a first part formed on the second side of the folding axis and a second part of the at least one additional turn formed on the first side of the folding axis, the first part and the second part of the at least one additional turn interconnected with a second inversion region that forms a stack with the first inversion region; and
folding the first turn and the at least one additional turn at the first inversion region and the second inversion region, respectively, around the folding axis.
