This paper proposes a space-vector dynamic model of the Induction Motor (IM) taking into consideration the iron losses in a state form, trying to improve some issues of the previously developed dynamic models. The main original aspects of the proposed model are the following: 1) it is based on the complete T electrical scheme of the IM, 2) it is written in a complete state form, involving in the formulation the entire set of state variables useful in FOC, 3) it includes the iron losses, separating them in hysteresis and eddy current ones, 4) it includes the effect of the stator leakage flux on the magnetic saturation, accounting for part of the effect of the load on the saturation. The proposed model has been implemented in numerical simulation in Matlab (R)-Simulink (R) environment and validated experimentally on a suitably developed test set-up.
