Home Contact ROTATING EQUIPMENT SCIENCE Tuesday, November 17, 2020 A CASE STUDY OF ABNORMAL SOUND FROM VFD MOTOR KARTHIK V. Variable speed drives have always raised challenges for the condition monitoring personnel due to its varying speed and load conditions and the necessity of fixing the operating parameters before data collection or use the techniques such as order tracking etc. to diagnose the faults. Here we are discussing an interesting case, where an abnormal sound, similar to a damaged bearing or rub sound, arose from the motor during the commissioning run, after being a standby for more than 6 months. Different tests were performed before concluding the results, which are explained below. The motor was in continuous service until stopped a few months back due to the decline in demand. The subject motor drives a single stage radial flow blower. Observations Abnormal sound noticed from the motor when operated in the minimum speed range during low load. Vibration spectrum |
