In this paper, an implementation and dynamic modeling
of a three-phase induction motor using Matlab/Simulink are
presented in a step-by-step manner. The model was tested by
two different ratings of a small and large induction motors.
The two simulated machines have given a satisfactory
response in terms of the torque and speed characteristics.
