Abstract
A stator winding bar comprises a plurality of strands that are transposed in the manner of a Roebel bar in an active part having a prescribed length, the active part being divided into several areas having different lengths arranged one after the other, in each area a transposition of the strands by a prescribed angle magnitude is provided, wherein the crimping distance within each area varies.
Claims7
A stator winding bar, comprising:
- a plurality of strands disposed in an active part having a prescribed overall length and divided into a plurality of areas arranged one after the other, each area having a different area length than that of an adjacent area and each area being divided into at least three segments arranged one after another;
- and
- wherein the plurality of strands is transposed in the manner of a Roebel bar within the active part such that a transposition of the strands by a prescribed angle magnitude in each area is provided, each strand including at least one crimping site in each area and each segment including at least two adjacent crimping sites of adjacent strands, wherein a crimping distance between two adjacent crimping sites of adjacent strands in one segment of each area differs from the crimping distance between two adjacent crimping sites of adjacent strands in at least one of the other segments of the respective area.
