IN FOCUS

Vibration in rotating machinery is a leading cause of premature failure, costly downtime, and safety hazards. For operators of vertical motors, one of the most important vibration-related concepts to understand is reed critical frequency (RCF). This natural frequency of a motor system plays a central role in determining whether a motor will operate smoothly or succumb to damaging resonance conditions.
