Abstract:The main objective of this article is propose a method for detecting broken bars faults in a three-phase induction motors through analysis of the starting current. Were used signal processing and analysis well-known techniques, such as Hilbert Transform and Wavelet Transform, adding the concept of Wavelet Energy. In order to establish a more robust and effective analysis, simulations were made for different operating conditions and broken bars. The methodology was also validated with experimental data obtained… Show more
