    Abstract: Certain aspects relate to a continuous winding formed from a conductor of rectangular cross-section, the winding having a compound bend in the crowns connecting successive linear segments where the compound bend does not stress the conductor insulation to its failure point. The compound bend can be formed by applying force to the conductor in a first direction, thereby shaping a first bend in the conductor to form a u-shaped conductor having a crown and two linear segments, where the crown includes a v-shaped bend and two straight segments on either side of the v-shaped bend that each connect to one of the linear segments. A second bend can be formed by applying force to the conductor in a second direction perpendicular to the first direction. The shape of the second bend can depend on the desired radius of the winding when circularly wound and positioned in a stator.
