ABSTRACT:
A coil for a two or multi-layer winding of an electrical machine includes twisted subconductors in each coil side and an end portion connecting the subconductors of each coil side. The degree of twist in each coil side is less than a full turn of 360.degree.. If the subconductors in the end portion are parallel to one another, the direction of twist in each coil side is the same. If the subconductors in the end portion reverse their positions, the directions of twist in the two coil sides are opposite.
