During operation of a rotary electric machine coolant tends to enter an air gap between a stator and a rotor thus producing drag losses. This is overcome by an arrangement for preventing the coolant from entering the air gap between the stator and the rotor. The rotary electric machine includes a housing (10) having a stator (12). The stator includes an armature winding (14) with end turns (26) extending from opposite ends thereof. A rotor (18) is journalled (20, 22) within the housing and the stator and is separated from the stator by an air gap (24). At least two nozzles (36, 38) are located within the housing, one adjacent each end of the armature, and directed at an associated set of end turns. A pair of partitions (80) are disposed within the housing, one for each end of the associated end turns and nozzle. A first air gap seal (90, 92) includes a resilient gasket sealingly engaging a corresponding one of the partitions and the tips of the adjacent end turns while a second air gap seal includes sheet-like seals, (94, 111) interposed between layers of the end turns. |
