Abstract
An electric machine includes a stator formed from a plurality of stacked laminations and defining a center bore and a rotor disposed within the center bore. The rotor is configured to output a rotational torque in response to an input current delivered to the stator. At least one of the stacked laminations of the stator includes a pattern of perforations disposed at a yoke portion of the stator to attenuate structure-bore transmission of vibration during operation of the electric machine.
