Order SpectrogramSynchronized spectrogram to the supply frequency (~50hz)Order 1 means 50hzSidebands of the rotor speed higher harmonyThe rotor speed is also unstable!Same anomaliesas seen in spectrumZoom in 1 <strong>for</strong> example*Colors indicates the currentpower spectrum (jet scale)
Conclusions1. An online MCM <strong>system</strong> can identify faults2. Coherence between phases can obtain immediateidentification whether the motor is normal orfaulty3. To discover all types of faults still need an expert inthe loop
