Abstract
A vehicle electric motor system includes an electric motor having a rotor. Multiple windings are mounted on the rotors individually having a coiled conductor including multiple conductor elements. A width of successive ones of the conductor elements is varied. At least one of the multiple conductor elements includes a continuous tapering body on the axis and alternatively at least one of the multiple conductor elements includes a smallest cross-sectional area having a first thickness approximately at a midpoint of the at least one of the multiple conductor elements and opposed ends positioned oppositely about the smallest cross-sectional area individually having a conductor element second thickness greater than the first thickness.
