The switched reluctance motor has a simple construction, low production cost, fault tolerance, high starting conjugate, robustness, absence of magnets or windings in the rotor. The present paper aims to model the motor using the finite element method. During the modeling of the construction aspects of the motor, sizing equations based on similar machines are applied, as well as calculations of copper losses. In this context, in the computational simulation the FEMM (Finite Element Method Magnetics) software was used, which allows the analysis of the magnetic flux density in the air gap under the relevant currents and the copper losses. Finally, the achieved results are compared to the analytic calculations to demonstrate the efficiency of the applied methods.Resumo: O motor de relutância variável possui uma construção simples, baixo custo de produção, tolerância a faltas, elevado conjugado de partida, robustez, ausência de ímãs ou enrolamentos no rotor. O presente trabalho tem por objetivo modelar o motor utilizando o método dos elementos finitos. Durante a modelagem dos aspectos construtivos do motor, são aplicadas as equações de dimensionamento com base em máquinas similares, assim como os cálculos das perdas no cobre. Neste contexto, na simulação computacional usou-se o software FEMM (Finite Element Method Magnetics), que permite a análise da densidade de fluxo magnético no entreferro sob as correntes de relevância e das perdas do cobre. Finalmente, os resultados alcançados são comparados aos cálculos analíticos demonstrando a eficácia dos métodos aplicados.
