In this context, the FEMM software was employed, which is based on the finite element method to perform the proposed simulations, and through the Triangle script, it automatically generates high-quality meshes using the Delaunay method. In this scenario, the torque magnitude and total losses resulting from the choice between aluminum or copper for the rotor bars of a given induction motor were investigated. Consequently, the results indicated that the torque and loss levels from the aluminum-based model were approximately 30% and 25% higher, respectively, compared to the copper-based model. In another article, the effects on magnetic induction and loss levels caused by the selection between the ferromagnetic materials 10JNEX900 (6.5% Si) and M235-35A (3.5% Si) for the rotor and stator cores were analyzed. The results showed that, for the analyzed case, the configuration with M235-35A achieved a maximum magnetic induction approximately 0.1 T higher compared to the maximum value obtained with 10JNEX900, while the ferromagnetic loss level of the 10JNEX900 model was around 17% lower than that of M235 35A, according to the Bertotti coefficients employed. In the final article, a mathematical model was established to calculate the Bertotti coefficients in order to estimate the ferromagnetic losses for the induction motor models using 10JNEX900 and M235-35A. The results indicated that, under the proposed conditions, the motor using M235-35A presented iron losses approximately 80% higher compared to those obtained with 10JNEX900.Acesso AbertoEletromagnetismoMotores de induçãoMétodo de BertottiMEFFEMMM235-35A10JNEX900ElectromagneticsInduction motorBertotti’s methodFEMFEMMM235-35A10JNEX900CNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::MATERIAIS ELETRICOSTrabalho de Curso - Graduação - MonografiaAttribution-NonCommercial-NoDerivs 3.0 Brazil
