The FPT is based on the engine division into layers and application of Maxwell’s equations, this methodology is able to consider the magnetic saturation and anisotropy of electrical steel and relate it to the motor equivalent circuit. The FTP has proposed two variations machine equation: The Induced Current Method (ICM) and the Predefined Current Method (PCM) which differ for the mode of obtaining the rotor current. To validate the TPC used two three-phase induction motors. The results of the proposed method were compared to those presented by the Finite Element Method (FEM) and were very promising. / Este trabalho apresenta uma metodologia de análise da máquina de indução trifásica em regime permanente, denominada Teoria de Propagação do Campo (TPC). A TPC é baseada na divisão do motor em camadas e na aplicação das equações de Maxwell. Esta metodologia é capaz de considerar a saturação magnética e a anisotropia do aço elétrico e relacioná-la ao circuito elétrico equivalente do motor. Dentro da TPC foram propostas duas variações de equacionamento da máquina: o Método de Corrente Induzida (MCI) e o Método de Corrente Pré-definida (MCP) que se diferem pela forma de obtenção da corrente presente no rotor. Para a validação da TPC utilizou-se dois motores de indução trifásicos de pequeno porte. Os resultados da metodologia proposta se mostraram muito promissores quando comparados aos apresentados pelo Método dos Elementos Finitos (MEF).
