STATOR WINDING HAVING CASCADED END LOOPS AND INCREASED COOLING SURFACE AREA

摘要

A dynamoelectric machine stator winding having cascaded end loops and increased cooling surface area is adapted to be placed in a plurality of circumferentially spaced axially-extending core slots in a surface of a generally cylindrically-shaped stator core. The stator winding includes a plurality of straight segments alternately connected at the first and second ends of the stator core by a plurality of end loop segments to form the winding. The end loops include first and second sloped sides meeting at an apex portion. The first and second sloped sides include at least one body portion offset in opposite radial directions to form a cascaded winding pattern and providing increased cooling surface area for the winding.
