A laminated rotor and stator are provided for a dynamoelectric machine. The rotor includes at least one end flange having a plurality of cooling apertures and at least one rotor inner vent lamination having a plurality of cooling apertures. At least one rotor outer vent lamination has a plurality of cooling apertures in communication with a first plurality of radially oriented ventilating slots. The end flange, rotor inner vent lamination and rotor outer vent lamination are configured together into a rotor lamination stack, and the plurality of cooling apertures form a generally axial cooling passage for a flow of a cooling medium.

Ventilated rotor and stator for dynamoelectric machine

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.

Axial cooled generator

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.
