ABSTRACT:
An improved cooling arrangement for a dynamoelectric machine of the type having a plurality of stacked laminations forming a stator core. The stacked laminations have a central bore for passage of a rotor therethrough and a plurality of uniformly spaced winding slots extending radially outward from the bore and terminating at an end at least partially through the laminations. Adjacent ones of the slots define pole pieces extending from the bore into a radially outer portion of the laminations. The improvement comprises a plurality of cooling air passages extending axially through the stacked laminations generally parallel to the central bore with each of the air passages being positioned adjacent the terminating end of a corresponding one of the winding slots. Each air passage has a radially outer shape corresponding generally to a radially outer shape of the winding slots and preferably have a crescent shape when viewed axially.
