| Abstract |
This paper presents two models for the simulation of a squirrel cage induction motor including the first space harmonics. The first model uses the generalised Park’s transformation applied to the rotor which allows to have a low computing time. The second model takes into account all the parameters of the squirrel cage and requires a huge computational power. It improves the precision of the all induction motor simulated variables. These two models are tested when the asynchronous machine presents rotor defects of broken bar type. We will show that the generalised Park’s transformation applied to the rotor is less appropriate for the fault diagnosis. Indeed, the analysis by Fast Fourier Transform of the stator current does not show up the sidebands due to the space harmonics instead of the complete model. A comparison between the two models and the experimental results are carried out in order to show the influence of each one for the diagnosis of defect. |
