(2016) Mark abstract The relation between evolving mechanical faultsin rotating electrical machines and their reflection in the machines’ electrical parameters still requires a lot of research.This implies serious obstructions in the evolution of e.g. MotorCurrent Signature Analysis as a complete and reliable conditionmonitoring technology. This paper presents the translation ofcommon bearing faults into specific rotor-stator movementsusing finite element modeling. Subsequently, a novel method toelucidate the complex relation between rotor movements andthe electrical parameters of an induction machine using anexperimental test setup is described, dimensioned and simulated.Replacing one of the induction machine’s bearings with an ActiveMagnetic Bearing will give the opportunity to create specific rotor movements and consequently evaluate different programmable mechanical faults and their reflection in the stator current and/or voltage with high relevance and reproducibility.
