Resumo
The present work proposes a numeric formulation for the determination of Carter's
factor as a function of the geometry of the slot of electric machines. This task is made by the
use of the Schwarz-Christoffel transformation. In order to reach the objective, there is the
need to calculate the Schwarz-Christoffel inverse transformation. This represents a non-linear
optimization problem. Therefore, it is proposed a methodology to calculate the parameters of
the Schwarz-Christoffel inverse transformation using genetic algorithms. The assessment of
Carter s factor is achieved considering polygonal domains with many vertices. The
transformation leads to a rectangular domain approach. Moreover, some case studies are
proposed and the methodology results are compared to traditional formulation results for the
Carter s factor, yielding some disparities.
