A rotating electrical machine comprising: a stator frame and a stator core with a stator/frame air gap between the two, and end windings extending out of the stator core; and a baffle for directing cooling air from the stator/frame air gap, characterised in that the baffle comprises: a first, disc-shaped section having a first surface facing an end face of the stator core and arranged to direct air flow (44, 45) from the stator/frame air gap in a direction substantially parallel to the end face of the stator core; a second frustoconical shaped section extending from a radially inwards edge of said first surface in an outwardly axial direction, the second section having a second surface extending rearwards of the first surface and arranged to direct the air flow from the stator/frame air gap along a path parallel to the outer surface of the end windings and along a radially outwards surface of the end windings; and a third, curved annular section, the third section having a third surface extending from an end of the second surface, the third surface curving from a substantially axial direction to a substantially radial direction, wherein the third surface is arranged to direct air flow around an extremity of the end windings. a stator frame and a stator core with a stator/frame air gap between the two, and end windings extending out of the stator core; and a baffle for directing cooling air from the stator/frame air gap, characterised in that the baffle comprises: a first, disc-shaped section having a first surface facing an end face of the stator core and arranged to direct air flow (44, 45) from the stator/frame air gap in a direction substantially parallel to the end face of the stator core; a second frustoconical shaped section extending from a radially inwards edge of said first surface in an outwardly axial direction, the second section having a second surface extending rearwards of the first surface and arranged to direct the air flow from the stator/frame air gap along a path parallel to the outer surface of the end windings and along a radially outwards surface of the end windings; and a third, curved annular section, the third section having a third surface extending from an end of the second surface, the third surface curving from a substantially axial direction to a substantially radial direction, wherein the third surface is arranged to direct air flow around an extremity of the end windings. a first, disc-shaped section having a first surface facing an end face of the stator core and arranged to direct air flow (44, 45) from the stator/frame air gap in a direction substantially parallel to the end face of the stator core; a second frustoconical shaped section extending from a radially inwards edge of said first surface in an outwardly axial direction, the second section having a second surface extending rearwards of the first surface and arranged to direct the air flow from the stator/frame air gap along a path parallel to the outer surface of the end windings and along a radially outwards surface of the end windings; and a third, curved annular section, the third section having a third surface extending from an end of the second surface, the third surface curving from a substantially axial direction to a substantially radial direction, wherein the third surface is arranged to direct air flow around an extremity of the end windings.
