ABSTRACT:
A damper for an electric machine (10) includes a shaft (20) and at least one shaft segment (26) concentric about the shaft (20) and operably connected to the shaft (20). The at least one shaft segment (26) includes a plurality of shaft slots (38) extending through a wall (40) of the at least one shaft segment (26) to increase torsional compliance of the at least one shaft segment (26). A driveline mounted electric machine (10) includes at least one rotor (16) located at a central axis (18) of the electric machine (10) and a damper. The damper includes a shaft (20) in operable communication with the at least one rotor (16) and at least one shaft segment (26) concentric about the shaft (20) an operably connected thereto. The at least one shaft segment (26) includes a plurality of shaft slots (38) extending through a wall (40) of the at least one shaft segment (26) to increase torsional compliance of the at least one shaft segment (26).
