Detalhes bibliográficos
Resumo:This work was developed in collaboration with WEGeuro Portugal. It presents the optimization of 8 high-voltage induction motors, with the objective of reducing the active material costs of these machines. WEGeuro has been manufacturing high-performance motors for decades. The opportunity to reduce the motor costs was well appreciated, and the following work was originated. Reducing the motor cost increases the company’s profit and competition in the market, whereas keeping its well-known high-quality standard. The optimization was based on modifying specific design parameters of the motors with WEGeuro's internal analytical optimization software. Among the available algorithms, the one chosen was the Nelder-Mead Simplex. The process began with individual optimizations for each motor; then, the optimizations were performed collectively to create a default design for motors with the same number of poles and further reduce their final costs. The dimensions of the slots, the core length, and the stator windings were the main design variables changed during the optimization process because the active materials of the motor (aluminum, copper, and steel) are more influenced by these parameters. Regarding the constraints, the starting current, the efficiency, and the maximum magnetic induction were the most important in the analyses. The results of the analytical software were later verified using the finite element method in Ansys Maxwell software. The saturation phenomena and the harmonics were also analyzed. At the end, the active material costs of the motors had a significant reduction, respecting the imposed constraints and manufacturing limits. As an additional result, the efficiency of the machines was improved and, in most cases, the harmonic content was mitigated.
