Hilbert versus Concordia transform for three-phase machine stator current time-frequency monitoring
This paper deals with mechanical fault diagnosis in three-phase induction machines from stator current measurements. According to machine models, mechanical faults lead to amplitude and/or phase modulations of the measured stator current with possibly time varying carrier frequency. The modulation diagnosis requires a univocal definition of the instantaneous phase and amplitude. This is perform...
متن کاملThree-Phase Induction Motor Stator Current Optimization
This research presents two mathematical –based optimal control systems for induction motor drives leading to stator current optimization and energy saving. The first is a classical optimal control system, which uses information on torque of the motor to generate the appropriate voltage amplitude that minimizes the induction motor stator current. The second is a genetic algorithm-based optimal c...
متن کاملShaft Misalignment Detection using Stator Current Monitoring
This paper inspects the misaligned of shaft by using diagnostic medium such as current and vibration. Misalignments in machines can cause decrease in efficiency and in the long-run it may cause failure because of unnecessary vibration, stress on motor, bearings and short-circuiting in stator and rotor windings. In this study, authors investigate the onset of instability on a shaft mounted on jo...
متن کاملSpeed Control of A Three Phase Current Forced Synchronous Machine Drive Based on A Simple Method
In this paper, a new method is proposed for the speed control of a three-phase current forced synchronous machine drive. This metohd is based on the use of an approximate constant commutation safety margin angle in the output thyristor bridge of the drive system as well as on the compenastion of stator magnetization reaction. The commutation process in the output converter of the machine driv...
