Generator armature cooling and air gap sealing system
First Claim
1. A rotary electric machine comprising:
- a housing;
a stator within said housing including an armature having a winding including layered end turns extending from opposite ends of the armature;
a rotor journalled within said housing and said stator and separated from said stator by an air gap;
at least two nozzles within said housing, one adjacent each end of said armature and directed at the associated end turns;
a pair of partitions within said housing, one for each end of said armature, each being located axially outwardly of the associated end turns and nozzle;
first air gap sealing means including a resilient gasket sealingly engaging a corresponding one of said partitions and the tips of adjacent end turns and sheet-like seals engaging and conforming to said end turn tips and engaging and gasket; and
second air gap sealing means including sheet-like seals interposed between layers of said end turns.

Abstract
A rotary electric machine including a housing having a stator. The stator includes an armature winding with end turns extending from opposite ends thereof. A rotor is journalled within the housing and the stator and is separated from the stator by an air gap. At least two nozzles 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 are disposed within the housing, one for each end of the armature. Each partition is located axially outwardly of the associated end turns and nozzle. A first air gap seal 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 interposed between layers of the end turns.
