Fault Diagnosis of Induction Motor using MCSA
نویسنده
چکیده
In this paper, the effects of induction motor rotor faults on the current and voltage of motor are studied through motor current signature analysis. This technique utilizes the results of spectral analysis of the stator current. The distortion of current waveform is generally very minute due to fault of induction motor so it is very difficult. In this paper, power spectrum of motor is taken to investigate frequency signature of rotor bar fault. The virtual instrument is developed to obtain the Power spectrum. The Virtual Instrument was build up by programming in LabVIEW 8.2. A three phase 0.5 hp, 415V induction motor is used for experiment in which rotor faults are replicated. The experiment conducted on motor show that Motor current signature analysis is reliable technique to diagnose the faults of induction motor.
