A winding for a rotor for use in an electrical generator utilized in the power generation industry. The winding includes a plurality of axial sections and a plurality of transversely oriented end arc sections. An integrated leg section extends from each end arc section to form an associated corner section at an intersection of each leg section and associated end arc section. Each leg section is affixed to an associated axial section at a joint that is spaced apart from an associated corner section such that the joint is not subjected to stress concentration which occurs at the associated corner section.
