The steady-state behaviour of an induction machine with a symmetric rotor cage and a faulty asymmetric stator is analyzed. The asymmetric machine is modeled by means of the space vector approach. The winding asymmetry is taken into account by considering each conductor of every single slot separately. Harmonic components of the permeance produced by the rotor slots are taken into account too. Harmonic slotting components of stator currents have been computed for different faulty machines affected by short circuits with different values of the dimensions of the rotor slots, different numbers of the rotor bars and different pole-pairs.

Abstract
The steady-state behaviour of an induction machine with a symmetric rotor cage and a faulty asymmetric stator is analyzed. The asymmetric machine is modeled by means of the space vector approach. The winding asymmetry is taken into account by considering each conductor of every single slot separately. Harmonic components of the permeance produced by the rotor slots are taken into account too. Harmonic slotting components of stator currents have been computed for different faulty machines affected by short circuits with different values of the dimensions of the rotor slots, different numbers of the rotor bars and different pole-pairs.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
