Abstract
A baffleis disclosed for directing cooling air in a rotating electrical machine comprising a stator core and end windings. The baffle comprises a first surfacearranged to direct air flow along an end face of the stator core, and a second surfacearranged to direct air flow along a radially outwards surface of the end windings. This may help to reduce turbulence in the airflow, thereby allowing more efficient transfer of heat. Furthermore, greater priority may be given to air flow through the rotor/stator air gap, and thus increasing air flow through the centre of the machine.
