    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： In accordance with one embodiment, the present technique provides a magnetic assembly for an electrical machine having a rotor core. The magnetic assembly includes a magnetic element having a top surface, a bottom surface and at least one side surface located between the top and bottom surfaces, wherein the bottom surface of the magnetic element is couplable to a peripheral surface of the rotor core. The magnetic assembly also includes a ferromagnetic layer disposed on the top surface of the magnetic element. The magnetic assembly further includes an electrically conductive element that circumscribes the magnetic element.
