Improved diagnosis of problems with critical VFD motor/machine systems

VFD motor/machine systems introduce a number of challenges that, for many organizations, will cause system failures until they adopt modern dynamic motor monitoring tools.

Maintenance professionals aren’t often aware of what is necessary to identify faults to avert catastrophic motor failures in variable frequency drive systems. This paper presents a pair of VFD applications, problems with those applications, and diagnoses using modern dynamic motor analyzers.
