ACOMPANHAMENTO PREDITIVO DE MOTORES DE INDUÇÃO TRIFÁSICOS ATRAVÉS DA ANÁLISE DE FLUXO MAGNÉTICO
Keywords:
Flux coil, Deterministic frequencies, MaintenanceAbstract
This paper considers the implementation, inside the three-phase induction motors, of a special sensor (flux coil) sensitive to electromagnetic waves, thus permitting to identify the deterministic frequencies related with broken rotor bars. The spectra acquired with the special sensor are compared with the ones come from a commercial sensor, which shows the efficiency of the first. The coils implemented in radial and in axial positions showed more significant results. It could still be seen from the analysis of magnetic flux that it is possible to diagnose the problem in frequency fl x 1 - x 1 fs, even though diagnosis in the frequency 1 x 2 x fl fs is common.
