Resumen:
A novel on-line stator core fault diagnosis method
for Induction Motors (IM) is proposed. This approach is based
on an adaptive state observer; it is derived from the IM dynamic
model considering stator iron losses. In this model the iron losses
are represented by an equivalent iron loss resistance (RFe). Stator
core fault causes important variations on iron losses and these
variations are reflected on the RFe. Therefore the proposed
adaptive state observer estimates RFe with the objective of
diagnosing stator core fault. Simulation and experimental results
for different fault severity conditions are showed. These results
demonstrated the validity of the method. In addition, simulation
results proved that the proposal is not sensitive to load torque
variations.RFe). Stator
