Abstract
A deflector is disclosed for deflecting air flow in a rotating electrical machine comprising a stator (), stator windings () and a housing (). The deflector comprises a sheet of material folded to form a deflecting portion () and a connecting portion (). The deflecting portion () is arranged to deflect airflow from a gap () between the stator and the housing towards the stator windings (). The connecting portion comprises one or more apertures () adjacent to the deflecting portion. The aperture helps to reduce or avoid the Coand{hacek over (a)} effect, and thereby improve the impingement of cooling air on the stator end windings.
