While at a power plant working on a large fan, the vibration analyst requested that a large mill motor be examined. The motor had been sent out to motor shops twice. In each instance, the vibration remained high when the motor was put back into operation. Attempts were made to field balance the motor, however, they were unsuccessful. The motor continued to have amplitudes of 8 mils of vibration, all of which [...]
