    Abstract: A cooling sleeve for an electric machine is provided. The cooling sleeve includes: a cylindrical body having an exterior surface, a first channel formed in the cylindrical body and having a first inlet for receiving a cooling fluid, and a second channel formed in the cylindrical body and having a second inlet for receiving the cooling fluid. The first inlet and the second inlet are formed on the exterior surface at a center along a length of the cylindrical body. A plurality of turbulators are formed in the first channel and the second channel and a cylindrical cover is configured to be disposed over the cylindrical body.

    Abstract: A generator assembly may include a bearing liner and a bearing retainer configured to reduce vibration response in a bearing assembly under high frequency operation of a rotor. The bearing liner may be configured to provide a clearance between the bearing assembly and an adjacent housing/bearing liner to prevent high vibration output from the bearing assembly on for example, the rotor shaft. The bearing retainer may include a recess to accommodate axial movement of the bearing assembly in response to rotation of the rotor. In some embodiments, the bearing retainer may include a dampener to dampen contact of the bearing assembly with the retainer.
