The machine is modeled in models, thus having a model closer to the real machine. The magneto-evolutionary. Inter -turn fault within the stator slot was two-dimensional modelling of the induction machine greatly studied. A stator current spectrum of both healthy and faulty reduces the computation time and memory space used. The machines is simulated. New frequency components of the line current spectra can appear as a consequence of the fault. These magnetic losses due to coils head are taken into account. The New components found were
