Abstract EN
The present paper proposes a method of diagnosis of faults of an induction motor due to broken-bar and massunbalance rotor through analysis of its no-load starting current.
Starting current is analyzed by discrete wavelet transform (DWT).
The discrete wavelet coefficients are processed to determine the spectral energy for different spectral frequency bands containing the harmonics due to fault and statistical parameters of detail coefficients are calculated for different levels of wavelet for faulty and healthy motors.
The parameters are used successfully for detection of fault in a motor.
Advantage of this method is that it requires less computational time and less processing power.
Also motor starting current being higher than the steady state current, this method does not require running the motor at load to obtain higher magnitude of current for better analysis.
This method has been validated in a laboratory prototype.
