摘要：

Rotor eccentricity in electrical machines determines the non-uniformity of the air-gap and gives rise to an unbalanced magnetic pull (UMP), which causes vibrations and noise emission, speeds up the bearing wear and can produce a rub between rotor and stator. In the paper, an overview about this subject is presented, by classifying the researches according to the type of machine (induction, synchronous, brushless), the type of eccentricity (static or dynamic) and the type of studied effect (definition of the fault indicators, calculation of the UMP, modelling the dynamic behaviour of the machine).
