    摘要： Methods and apparatus for assembling a wind turbine generator are provided. The wind turbine generator includes a core and a plurality of stator windings circumferentially spaced about a generator longitudinal axis, a rotor rotatable about the generator longitudinal axis wherein the rotor includes a plurality of magnetic elements coupled to a radially outer periphery of the rotor such that an airgap is defined between the stator windings and the magnetic elements and the plurality of magnetic elements including a radially inner periphery having a first diameter. The wind turbine generator also includes a bearing including a first member in rotatable engagement with a radially inner second member, the first member including a radially outer periphery, a diameter of the radially outer periphery of the first member being substantially equal to the first diameter, the rotor coupled to the stator through the bearing such that a substantially uniform airgap is maintained.

    摘要： A fluid transfer device and a method for conveying a fluid from a fluid transfer device to a rotating member are provided. The fluid transfer device includes a housing disposed around a first rotating member extending along an axis. The housing has a first plurality of apertures extending therethrough that communicate with the fluid source. The first rotating member has a second plurality of passageways extending from a first exterior surface of the first rotating member to a third passageway extending generally axially within the first rotating member. Further, at least a portion of the second plurality of passageways communicate with at least a portion of the first plurality of apertures, wherein the fluid flows through the first plurality of apertures and the second plurality of passageways to the third passageway in the first rotating member.

    摘要： An electrical machine stator is disclosed that includes a stack of laminations configured to be assembled together so as to define at least one stator tooth. The stack of laminations may include a plurality of nesting laminations and a plurality of shim laminations. Each nesting lamination may include a first edge section, a second edge section and a middle section extending between the first and second edge sections. At least one of the first edge section and the second edge section of each nesting lamination may be configured to be engaged against at least one of the first edge section and the second edge section of an adjacent nesting lamination when the stack of laminations is assembled together. Additionally, at least one shim lamination may be disposed between each pair of adjacent nesting laminations.
