Abstract :
A new strategy for stator fault diagnosis in induction motors is presented in this paper. The proposed strategy is based on the generation of a vector of specific residual using a state observer. The residual allows the detection of the faulted motor phase and the quantification of the number of shortcircuited turns. This strategy is robust to motor load variation and power supply perturbations
