Abstract
A multiplanar conductor bar for electric machines comprising subconductors superimposed radially in a number n of circumferentially mutually adjacent planes, n being a whole, even number between six and ten, inclusive, and transposed by at least 360.degree.. A total of two groups of two adjacent subconductor planes, respectively, are formed at upper and lower sides of the multiplanar conductor bar by exclusively mutual crossover of the semiconductors of the two adjacent planes. A total of n/2-1 groups of four adjacent subconductor planes, respectively, are formed at the upper and lower sides of the multiplanar conductor bar by exclusively mutual crossover of the subconductors of the respective four adjacent subconductor planes and exclusively in a transition between the respective outer and the respective inner planes of the four planes. The respective groups of four adjacent planes are mutually offset at the lower side with respect to the upper side by two subconductor planes. Each of the subconductors traverse all layer levels between two crossover points in each subconductor plane alternatingly in descending and ascending order in successive planes. The individual crossed-over s…
