The paper proposes a multiobjective optimization procedure for five-phase induction machines based on the NSGA-II (nondominated sorting genetic algorithm). In the optimization procedure, two objective functions are used (efficiency and cost of conductor material) along with 14 design variables, producing a large number of viable solutions. The design variables describe geometrical constraints, electrical...
The unbalanced operation of five-phase induction machines is described using the method of steady state symmetrical components and including aspects not yet considered, such as the changes in the airgap induction. Starting from the dynamic equations, described by instantaneous symmetrical components, sequence equations are obtained in terms of steady state symmetrical components, thus establishing...
