Abstract-This paper presents a new detection method for broken rotor bar fault (BRB) in induction motors based on the estimation of signal parameters via YULE Walker Auto Regression (YUL-AR) power spectral density estimate method and MUSIC pseudo spectrum. The performance of the two aforementioned technique are tested with the simulated stator current signal of an induction motor with BRB. The results obtained from technique show consistent result with established techniques. The technique is capable of correctly identifying the frequencies of the BRB characteristic components but limited accuracy result for amplitudes and harmonic frequencies components. . Results obtained proves that the proposed method is a promising choice for BRB detection in induction motors operating under normal and transient load condition.
