11. Vibration measurements of KEC 630 Frame at 3000 rpm on 9.8.2006
It was observed at the site that the cooling fan provided at the Motor NDE site was cracked
2. There is some disturbance in the motor vertical direction both on Motor DE and NDE which is reflecting both in frequency and time wave form. This needs to be investigated
3. High noise floor was observed only in vertical direction on both Motor DE and NDE as shown in the frequency spectrum
