Abstract
Certain exemplary embodiments comprise a method that can comprise, via a device that originates sub-harmonic vibrations, applying a vibration treatment, to a rotor of an electric motor for a predetermined time period. The rotor can be thermally sensitive. The vibration treatment can be adapted to reduce internal stresses in the rotor, thereby reducing a vibration level of the rotor.
