Popis: Gears are widely used in different domains, aeronautics, automotive and machines tools manufacturing etc. … Therefore, monitoring these mechanical systems have been a huge scientific and industrial trend recently. Different studies were orientated to its investigating using different techniques in order to study the sensitivity of each. Motor Stator Current Analysis (MSCA) was one of the highlighted techniques for its easy accessibility and accuracy. The mechanical system generates torque oscillations which leads to a frequency and amplitude modulation effects on the stator current in the asynchronous machine. Within this context, this study was done on an experimental test bench composed of a geared motor and a helicoidal gears. The current signal was recorded using clamp meter and presented on LMSTestLab. The electromagnetic interaction starts to get visible in the mechanical frequencies seen in the sidebands around the motor frequency. In this paper, some of the results would be present to illustrate the electro-mechanical interaction between the mechanical system and the electrical part, which is itself composed of an asynchronous motor and an integrated gearbox.
