The purpose of this study is diagnosis the fault of induction machine, through detection of
broken bars by stator current analysis. Therefor we present a multi-winding model for the
simulation of faults as part of the fault detection study, and test the behavior of the machine in
the healthy and faulty state. In this paper it is focus the signal processing technique for
detecting defects. This technique is based on continuous wavelet transform (CWT) to detect
and locate defects, by using the multi-level decomposition for the detection of defects and the
location of the broken bars at the rotor. The findings of this research results show the
importance of this technique for the analysis of fault signatures in healthy and defective cases.
