Abstract: This experimental work aims to diagnose multiple mechanical failures such as the mass imbalance, misalignment and wear of gear teeth. For large industrial electromechanical drives systems, these mechanical abnormalities are more virulent after those bearings which are generally the main cause. Traditionally, to monitor and diagnose these failures in transmissions, the analysis of the most discussed vibration and acoustic signals were mostly in use. However, the innovative approach of this publication offers a combination of MCSA currents of the stator and neutral phase with the visual interpretation of patterns extracted from the 3D representation of the currents phasic square. The experimental validation was carried out on an induction motor of 3 kW a reducer coupled to three levels.
