This paper investigates different types of faults for electrical machines with reference to an induction motor and to papers published in the last ten years. A comprehensive list of references is reported and the faults are classified into the following main types: 1) Rotor faults; 2) Stator faults; 3) Mechanical faults; 4) Electrical faults. Fault(More)
The dynamic behavior of structures, in particular, that of a rotor, containing cracks is a subject of considerable current interest. In the present study, the influence of a transverse surface crack, both open and breathing conditions, on the mechanical impedance of the rotor-bearing system, has been investigated by FEM analysis for flexural vibrations. The(More)
Measurements were done to determine the influence of a transverse crack on the mobility of a rotor-bearing system. The results show that the mobility changes substantially due to the presence of crack and follows definite trends with the crack depth and direction of force application. The significant changes in mobility were observed at the natural(More)
