<p>A cooling assembly for a rotating electrical machine is disclosed. The cooling assembly comprises a plenum (40, 42; 60; 70) located within the machine housing (26, 28). The plenum distributes air flow produced by an external fan (36, 38) within the interior of the machine. The plenum comprises a first chamber, and is arranged to receive airflow via a second chamber. The second chamber may be formed from an external plenum, or by an internal partition within the plenum. An air inlet duct (62, 72) may admit air tangentially into the plenum. This may improve the distribution of airflow within the machine.</p> |
