Validation of a Transient Model for Induction Machines Considering Saturation and Current Displacement using Transient FEM

Transient simulations of induction machines can pose a challenging task. This paper shows how an induction machine model which considers both main field saturation and current displacement in the rotor bars can be built. The model is implemented in MATLAB/Simulink and the results are validated using transient FEM calculations of short-circuit operation in ANSYS Maxwell and FEMAG TS. The differences between the analytical model and the FEM results are discussed and the limitations of the analytical model are laid out.
