This paper presents an experimental study on diagnosis of eccentricity fault in permanent magnet
synchronous motor (PMSM). The study carried out by analyzing the harmonics obtained using Power
Spectral Density (PSD) of stator current and voltage at no load condition. Motor stator current and
voltage are uploaded to pc with software of used inverter and their harmonics obtained by using
LabVIEW Signal Express Toolbox program for healthy and faulty condition. In addition, performance
of the motor over the period of starting up to the steady state is investigated. The experimental results
are illustrated in graph diagrams and results showed that the presented method is very effective and
easy to use for prognosis of static eccentricity fault.
