Abstract
Induction motors are the workhorse of modern industry because of their versatility and robustness. The diagnosis of mechanical load and power transmission system failures is usually carried out through mechanical signals such as vibration signatures, acoustic emissions, motor speed envelope. The motor faults including mechanical rotor unmbalances, broken rotor bar, bearing failure and eccentricities problems are reflected in electric, electromagnetic and mechanical quantities. The recent research has been directed toward electrical monitoring of the motor with emphasis on inspecting the stator current of the motor. The stator current spectrum has been widely used for fault detection of induction motor. The current signature analysis of motor is the useful technique to assess on machinery health condition monitoring. This paper describes the motor condition monitoring by the current signatures paralleled with vibration signatures analysis of induction motors. Condition monitoring on the roller bearing and the journal bearing for large vertical pumps in power plant is conducted to investigate for motor fault detection and diagnosis.
