Abstract
This paper examines the wide-band vibroacoustic emissions
of a medium power industrial wound rotor induction machine
(WRIM) design operating with balanced windings and also
with a stator winding fault. The aim of the presented study is
to enable a clearer understa
nding of the possible spectral
content of the WRIM vibration and acoustic emission signals
in healthy and electrical fau
lt conditions, with a view to
assessing the possibility of vibroacoustic based electrical fault
recognition. For this purpose,
an experimental study is
undertaken on a laboratory test rig in which the low frequency
spectral content of the synchro
nously recorded vibration and
acoustic emissions signals is mapped and correlated for
healthy and faulty operating conditions. It is shown that the
wide band winding fault induced changes can be clearly
correlated and recognised in
both the vibration and the
acoustic emission signals of the
investigated machine design
of a medium power industrial wound rotor induction machine
(WRIM) design operating with balanced windings and also
with a stator winding fault. The aim of the presented study is
