    摘要： A wind turbine is provided having a drivetrain with a gearbox and a gearbox housing, at least one gear stage and an output shaft coupled within the housing. The gear stage exerts an axial thrust force on the output shaft during operation of the wind turbine. A generator includes a generator housing and an input shaft connected to the output shaft of the gearbox. The generator includes a rotor and a stator coupled to the generator housing. The rotor is coupled to the input shaft such that the rotor is positioned radially inward from the stator. At least one bearing is shared between the gearbox output shaft and the generator input shaft, and this bearing carries a portion of the axial thrust force. The generator is skewed to exert an opposing axial thrust force on the input shaft, so that the axial thrust force carried by the bearing is reduced.

    摘要： A gas turbine engine assembly includes an electromagnetic machine for extracting power from the turbine engine. The electromagnetic machine includes an outer rotor and an inner rotor rotatably supported adjacent to a stator disposed between the inner and outer rotors. The stator has an inner set of windings disposed on an inner surface adjacent to the inner rotor, and an outer set of windings on an outer surface of the stator adjacent to the outer rotor. The inner stator windings form a set of multiple-phase windings, and the outer stator windings form a set of multiple-phase windings.
