Modeling of squirrel cage induction machine with S - function in MATLAB Simulink

The goal of this paper is to develop a S-function in MatLab Simulink for a symmetrical induction machine with squirrel cage rotor, in abc coordinates, for having direct access to rotor bars currents. We also use the circuit equivalent method (MEC), for having a hybrid mathematical model. This hybrid model is a simplified combination between abc frame model and MEC For the simulation model of induction machine, was used a real parameters from a 4kW machine.
