Abstract

A rotor assembly (12) of an electric machine (10) includes a rotor body (16) and a shaft assembly (18) positioned at a central axis of the rotor assembly, and operably connected thereto. The shaft assembly includes a main rotor shaft (32) operably connected to the rotor body, a center drive shaft (34) located inside of the main rotor shaft, and a hydraulic damper sleeve (46) located radially between the main rotor shaft and the center drive shaft. The hydraulic damper sleeve defines a plurality of cavities (52) between the hydraulic damper sleeve and the center drive shaft. The hydraulic damper sleeve is configured to urge a fluid into and out of the plurality of cavities thereby damping relative circumferential motion between the main rotor shaft and the center drive shaft. A plurality of flow restrictors are configured to easily allow fluid into the plurality of cavities, while restricting flow of fluid out of the plurality of cavities.
