Stator winding having cascaded end loops
First Claim
1. A stator for a dynamoelectric machine, comprising:
- a generally cylindrically-shaped stator core having a plurality of circumferentially spaced axially-extending core slots in a surface thereof, said core slots extending between a first and a second end of said stator core; and
a stator winding including at least one layer of conductors having a plurality of continuous phases, each of said phases having a plurality of substantially straight segments disposed in said core slots, said straight segments of each phase alternately connected at said first and second ends of said stator core by a plurality of end loop segments to form said winding, said straight segments having a first substantially rectangular cross-sectional shape, said straight segments of said at least one layer being in a same radial distance from a central axis of said stator core, wherein at least one of said end loop segments include first and second sloped sides meeting at an apex portion, at least one of said first sloped side and said second sloped side having a body portion offset in a first radial direction within said at least one layer, wherein said end loop segments form a cascaded winding pattern.

Abstract
A dynamoelectric machine stator winding having cascaded end loops is adapted to be placed in a plurality of circumferentially spaced axially-extending core slots in a surface of a generally disk-shaped stator core. The core slots extend between a first and a second end of the stator core. The stator 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. At least one of the first sloped side and the second sloped side has a body portion offset in a first radial direction. Each of the end loop segments form a cascaded winding pattern.
