Deflector For Rotating Electrical Machine
Abstract: A deflector is disclosed for deflecting air flow in a rotating electrical machine comprising a stator (8), stator windings (10) and a housing (12). The deflector comprises a sheet of material folded to form a deflecting portion (42) and a connecting portion (44). The deflecting portion (42) is arranged to deflect airflow from a gap (14) between the stator and the housing towards the stator windings (10). The connecting portion comprises one or more apertures (48; 52; 54; 56; 58) adjacent to the deflecting portion. The aperture helps to reduce or avoid the Coanda effect, and thereby improve the impingement of cooling air on the stator end windings.
