Abstract:
A rotor for an electric machine includes a shaft that is rotatable about an axis and defines a first diameter normal to the axis. A first core portion defines a first aperture having a first aperture diameter that is larger than the first diameter. The first core portion is positioned adjacent the shaft to define a first space. A second core portion defines a second aperture having a second aperture diameter that is larger than the first diameter. The second core portion is positioned adjacent the shaft to define a second space. A damping member is positioned in the first space and the second space. The damping member at least partially interconnects the shaft, the first core portion, and the second core portion.
