The features of stator currents and core vibration signals are investigated in order to improve the MCSA diagnostic procedure to detect rotor faults in induction machines. In fact the usual procedure based on the sideband components near the fundamental one may fail for the presence of inter-bar currents that reduce the amplitudes of these components. On the other hand the inter-bar currents modify the core vibration; therefore the analysis of both line currents and core vibration signals may increase the effectiveness of the diagnostic procedure.

Abstract
The features of stator currents and core vibration signals are investigated in order to improve the MCSA diagnostic procedure to detect rotor faults in induction machines. In fact the usual procedure based on the sideband components near the fundamental one may fail for the presence of inter-bar currents that reduce the amplitudes of these components. On the other hand the inter-bar currents modify the core vibration; therefore the analysis of both line currents and core vibration signals may increase the effectiveness of the diagnostic procedure.| File | Dimensione | Formato | |
