Variable frequency drives (VFDs) have become a preferred method of process control for electric motor driven equipment ranging from vertical water pumps to centrifugal air fans. The following is a basic discussion of risks of using a VFD with direct driven centrifugal fans and methods of mitigating those risks to maintain equipment reliability.

The ISO 10816-3 standard provides criteria for evaluating the vibration of machinery according to measurements taken on non-rotating parts, such as bearings, bearing pedestals, or housings. It serves as a general guideline for determining overall machine condition based on the magnitude of vibration and changes in vibration levels over time. While these aren’t always the only factors that need to be considered when identifying faults, the standard is very useful for performing basic vibration analysis.
