In this paper, we discuss the diagnosis of stator and rotor defects in induction machines. After describing the various defects that can occur on these, we propose a multi-winding model of the asynchronous machine that simulates stator faults for short-circuiting or phase-out. Then, we present a model based on the coupled electrical circuit’s method. This model makes it possible to study the influence of a bar fault on the general behavior of the asynchronous motor. In addition, we have studied the phenomena created by these defects on the different temporary variables of the machine, then we particularly interested in the development of new identification techniques. The latter are based on the evaluation of stator current spectrum indices calculated from a Fourier transform in the case of a stator or rotor defect. Finally, the results obtained with this approach make it possible to detect the presence of a defect and to locate its origin.
