OPTIMAL VOLUME AND SLIP OF A THREE PHASE INDUCTION MOTOR USING DIFFERENTIAL EVOLUTION

Abstract

The multiobjective engineering project is inherently conflicting. It provides an improvement in one of the objectives, but a decline in the other. The three phase induction motor with a wound rotor is widely used in the industry, because it´s simple, resistant and cheap compared with other types of engines. Regarding the context explained above, it is an interesting research theme, which is directly related to the fabrication costs of the engines. The object of this article, is the formulation and resolution of the three phase induction motor considering: (i) volume minimization and (ii) motor slip minimization. For this purpose the MODE (Multiobjective Optimization Differential Evolution) algorithm, was used, and the results are confronted with those obtained with the NSGA II (Non-dominate Sorting Genetic Algorithm).
