Abstract:
1. A reduced stress rotor, the rotor comprising: a shaft with a shaft axis; a pole extending radially outward from the shaft; a coil winding positioned on the pole; the pole having a planar pole face and a planar overhang face, the planar pole face oriented orthogonally with the planar overhang face, the planar overhang face oriented orthogonally with a radially outward force exerted by the coil winding, the coil winding oriented orthogonally against the planar overhang face by the radially outward force; and an intersection region between planes of the planar pole face and the planar overhang face comprising: wherein the coil winding directly abuts both the planar pole face and the planar overhang face.
