Otimização computacional dos parâmetros do rotor em Máquinas Síncronas de Relutância

Abstract

This work aims to simulate a synchronous reluctance machine using the finite element method and to optimize the parameters of four different rotor topologies using the differential evolution algorithm. To this end, the open-source finite element method (FEM) software FEMM (Finite Element Method Magnetics) is employed, together with the PyFemm library, which allows automation of simulation routines and facilitates machine modeling, and the Python language, used for processing and analyzing the obtained results. The adopted methodology is based on the stator of a 2 HP induction machine. In this context, the machine's original rotor is replaced by reluctance rotors with distinct geometries, aiming to optimize torque and torque ripple. Thus, the performance of each topology is expected to be evaluated, identifying the most efficient geometry for application in synchronous reluctance machines.
