Because of initial manufacture and ageing phenomenon, rotating machines present an
inherent mechanical disequilibrium. When a small mechanical unbalance fault affects the …

Traditional fault diagnostic techniques using motor current signature analysis is, generally,
based on the assumption of a constant load torque. In fact, due to the design, construction …

Rotor imbalance is the most common cause of machine vibration. In practice, rotors can
never be balanced perfectly owing to manufacturing errors such as porosity in casting, non …

The feasibility of using stator current measurements in order to detect mechanical problems
in electric rotating machinery has been proven by many authors several decades ago …

Mechanical rotor imbalances and rotor eccentricities give rise to specific mechanical
vibration, and certain electric, electromagnetic and mechanical harmonics. The extent and …
