Abstract Conductor bar for insertion into a core notch of an electrical machine, includes partial conductors disposed in three longitudinally extending planes, the partial conductors being twisted together, and, to compensate for radial and tangential stray fields at overhanging end portions of the bars as well as for core notch transverse field, the number of partial conductors for each of the planes being uneven, the partial conductors of the outer planes having a twist of 90* over an initial sixth of the length thereof, a twist of 180* over the succeeding second to fifth sixths thereof and a twist of 90* over the sixth sixth thereof, and being alternatingly stranded together in the middle plane, and the partial conductors of the inner plane in the initial sixth, the second to fifth sixth and the sixth sixth of the length thereof having a doubled twist of 180*, 360* and 180*, respectively.
Conductor bar for insertion into a core notch of an electrical machine, comprising partial conductors disposed in three longitudinally extending planes, including a middle plane and two outer planes, said partial conductors being twisted together to compensate for radial and tangential stray fields at overhanging end portions of the bars as well as for the core notch transverse field, the number of partial conductors for each of said planes being uneven, the partial conductors of said outer planes having a twist of 90* over an initial sixth of the length thereof, a twist of 180* over the succeeding second to fifth sixths thereof and a twist of 90* over the sixth sixth thereof, and being alternatingly stranded together in the middle plane, and said partial conductors of said inner plane in said initial sixth, said second to fifth sixth and said sixth sixth of the length thereof having a doubled twist of 180*, 360* and 180*, respectively.
