The effects of inverter harmonics on motor current fault signatures are studied in detail in this paper. According to theory and experimentation, the fault signatures caused by the inverter harmonics are similar and comparable to those generated by the fundamental harmonic of the line current. Unlike the utility-driven motor, monitoring the current of the inverter-fed motor is considerably noisy, which can mask the fault signatures and render a wrong fault warning. Therefore, the proposed additional fault data processing technique is expected to support the inverter-fed motor fault decision making algorithms effectively. The theoretically derived bearing fault relations are found to match the experimental results. In order to confirm these claims, outer race bearing faults are tested and the line current spectrum of the faulty motor is compared to the healthy one.

Low order PWM inverter harmonics contributions to the inverter-fed induction machine fault diagnosis Akin, Bilal; Orguner, Umut; Toliyat, Hamid A.; Rayner, Mark (Institute of Electrical and Electronics Engineers (IEEE), 2008-02-01) In this paper, the effects of inverter harmonies on motor current fault signatures are studied in detail. It is theoretically and experimentally shown that the fault signatures caused by the inverter harmonies are similar and comparable to those generated by the fundamental harmonic on the line current. Theoretically-derived extended relations including bearing fault, eccentricity, and broken rotor bar relations are found to match experimental results. Furthermore, it is observed and reported that the asymm...
Line Current Analysis for Bearing fault Detection In Induction Motors Using Hilbert Transform Phase Oumaamar, M. E. K.; Razik, H.; Rezzoug, A.; Khezzar, A. (2011-09-10) The present paper focuses by means of an experimental study, on the effect of a bearing fault on the stator current signatures in induction motors. The variation in the amplitude of the characteristic components is not so significant. For that and in order to depict the presence of the fault harmonic signatures, the authors used the phase analysis of Hilbert transform applied on the spectrum modulus of the line current.
Performance analysis and comparison of reduced common mode voltage PWM and standard PWM techniques for three-phase voltage source inverters Un, E; Hava, Ahmet Masum (2006-03-23) This paper investigates the performance characteristics of the reduced common mode voltage (RCMV) PWM methods for three phase voltage source inverters and provides a comparison with the standard PWM methods. PWM methods are reviewed and their pulse patterns and common mode voltage patterns illustrated. The AC output current ripple, DC link input current ripple, and output voltage linearity characteristics of each modulation method are thoroughly investigated by analytical methods and simulations. The analys...
Equipotential projection-based magnetic resonance electrical impedance tomography and experimental realization Ozdemir, MS; Eyüboğlu, Behçet Murat; Ozbek, O (2004-10-21) In this study, a direct, fast image reconstruction algorithm, based on the fact that equipotential lines are perpendicular to current lines in a volume conductor, is proposed for magnetic resonance electrical impedance tomography (MR-EIT). The proposed technique is evaluated both on simulated and measured data for conductor and insulator objects.
Low-cost motor drive-embedded fault diagnosis a simple harmonic analyzer AKIN, Bilal; TOLIYAT, Hamid A.; Orguner, Umut; RAYNER, Mark (2007-03-01) The reference frame theory and its applications to fault diagnosis of electric machinery as a powerful tool to find the magnitude and phase quantities of fault signatures are explored in this paper. The core idea is to convert the associated fault signature to a dc quantity, followed by calculating the signal average value in the new reference frame to filter out the rest of the signal harmonics, i. e. its ac components. Broken rotor bar and rotor eccentricity faults are experimentally tested both offline u...
