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 subsea pump drive employs a permanent magnet (PM) motor to drive a subsea pump. The PM motor rotor in one embodiment is canned with a non-magnetic material such as inconel that can provide a desired level of corrosion protection. The PM motor provides a subsea pump drive that is smaller and more efficient, having a high power factor than a subsea pump drive utilizing a conventional induction motor. The PM motor subsea pump drive eliminates the necessity for a topside storage tank and associated fluid transfer lines when the motor rotor is cooled with processed fluid.

摘要： This document discusses, among other things, a stator with transposition between the windings or coils. The coils are free from transposition to increase the fill factor of the stator slots. The transposition at the end connections between an inner coil and an outer coil provide transposition to reduce circulating current loss. The increased fill factor reduces further current losses. Such a stator is used in a dual rotor, permanent magnet machine, for example, in a compressor pump, wind turbine gearbox, wind turbine rotor.
