The paper reviews the main faults identification of electric machines based on amplitude versus time and amplitude versus frequency vibration analysis. The aim of the paper is to introduce a new method in determining rotor faults based on stator vibration. The analysis method uses a multi-channel vibration analyzer provided with three accelerometers, set in a plane perpendicular to the stator axis. The method is suitable for determining rotor faults generated by the stator vibrations, other than those due to current harmonic components or supply voltage unbalance. The SvanPC software allowed the determination of the characteristics regarding velocity vibration versus time and versus frequency. Their interpretation permitted to determine the fault points on electrical machines in two industrial applications.
