Abstract :
Induction machine is widely used in industrial applications, and currently numerous researches deals with its on line monitoring. A great on line monitoring would provide fault diagnosis, optimal use and quality management. However, diagnosis is, until today, mainly based on vibration analysis and/or motor current signature analysis (well known as MCSA). This paper presents a new approach in the whole electrical drive diagnosis thought original measurements. The first part shows that the measures of the electromagnetic field emitted on the DC bus bar of the inverter can provide a relevant signature for the spectral analysis of the power drive. The second part deals with the in sight simulation prospectives, through the widely spread partial element equivalent circuit (PEEC) modelling of the surfacic conductor structures
