Abstract: An apparatus for venting a stator core having a plurality of slots through which stator windings extend is provided. The apparatus includes a first ventilation layer for positioning at an end of the stator core. The first ventilation layer includes an inner set of circumferentially spaced slots that correspond to the plurality of slots and through which the stator windings extend, and an outer set of slots radially distanced from the inner set of slots. A second ventilation layer for positioning between the first ventilation layer and a stator core flange of the stator core is also provided. The second ventilation layer includes a set of ventilation slots providing a flow path between the stator windings to the outer set of slots.

Abstract: A structural integrity monitoring system includes a structure, at least two vibration monitoring devices mounted to the structure. Each of the at least two vibration monitoring devices outputs a vibration response signal. The structural integrity monitoring system also includes a controller operatively connected to each of the at least two vibration monitoring devices. The controller is configured to calculate a predicted vibration response based upon a vibration mode shape and the vibration response signal. The controller then compares the predicted vibration response against a measured vibration response to detect changes in the structure.

Abstract: A wind turbine having a generator is provided. The generator includes a rotor and a stator having a stator lamination, one or more flange rings and one or more core rings. The stator lamination includes a plurality of axial flow passages and the one or more core rings include a plurality of core ring axial flow passages that are aligned with the plurality of axial flow passages in the stator lamination. The plurality of axial flow passages in the stator lamination have a substantially triangular cross-sectional shape.

Abstract: A generator includes a housing and a stator arranged within the housing. The stator includes a first end that extends to a second end, and a plurality of axial flow passages extending between the first and second ends. The generator also includes at least one air flow re-direction member provided on at least one of the first and second ends of the stator. The at least one air flow re-direction member fluidly connects adjacent ones of the plurality of axial flow passages. The at least one air flow re-direction member guides an air flow passing though one of the plurality of axial flow passages in a first direction into an adjacent one of the plurality of axial flow passages in a second direction, the second direction being distinct from the first direction.
