This paper presents an analytical and laboratory study of the
behavior and evolution of the symmetrical components of both
voltage and current of a three-phase induction motor as a function of
the load torque applied to it and to increasing in the
imbalance which
effect the electrical grid. The effect of unbalanced voltages in the
voltage source will be also examined on the distribution of motor
currents in the three lines and on its performance.
This paper presents an accurate mathematical model of threephase
induction motor for both transient and steady-state studies. this
model takes into account the network harmonics, Skin Effect and
Stator and Rotor Magnetic Saturation. and to be able
to present the
real motor and its internal physical phenomena better than the
existing classical models.
