A hybrid kangaroo algorithm to assess the state of health of electric motors

Abstract

Even if the asynchronous machine is widely used in industrial process under speed variable, we have to monitor the process which is composed of an inverter and a motor in an enclosed space. Thus, the stator current is not accessible and the AC supply line current is only available to monitor the system in comparison to a motor connected directly to the power supply. In this paper, we focus our attention on the tracking of faulty lines rising up in the supply line current due to a rotor bar defect. We suggest to use a meta-heuristic method to tackle this problem. In this paper a hybrid kangaroo and a non-linear great deluge are taken into consideration to track these defective lines thanks to the analysis of the supply line. Experiments results show the effectiveness of this approach.
