More Information
Summary:Embodiments of the disclosure can include a method for reducing or repairing vibration-caused damage in a stator bar (22), and a dynamoelectric machine (2) resulting therefrom. The method for reducing vibration-caused damage in a stator can include applying, from within a ventilation slot (34) of a stator core (10) a liquid based vibration-absorbing material onto a side ripple spring (30A,30B), the side ripple spring (30A,30B) being in contact with a stator bar (22) and the stator core (10); and allowing the liquid based vibration-absorbing material to cure, wherein the cured vibration-absorbing material remains in contact with the side ripple spring (30A,30B) for absorbing stator vibrations.
