SUMMARY This paper presents a finite element model for the development of stator current diagnosis techniques based on the spectral analysis of the state variables on induction motor. Non‐linearities terms existing in the stator current due to the fault are analysed and concluding that these indicators can lead to a frequency matching of harmonics related to broken bar fault. In addition, this paper covers the limitations that two‐dimensional finite element models are having with respect to conical eccentricity and axial effects in the electric device.
