<p>Cooling air which has passed through a screen (22) is propelled by a centrifugal fan (24) on the main motor shaft through the rotor (5) using ducts (27) and also through the stator (8) which has larger rectangular ducts (31). A second centrifugal fan (28) also mounted on the main motor shaft assists in expelling the rotor air (F6) to atmosphere (F7) through ducts shared with the stator air (F8)</p> |
