Be aware! - Rotating equipment changes can lead to destruction due to its natural frequency

A lot of companies install nowadays frequency converters (VFD) to make machines rpm variable in order to run machines at different operating conditions to increase production.

Be aware of the impacts of changing these conditions or designs. We see these situations frequently!

Learning Objectives

  • What is "natural frequency"? What is a "forcing frequency"?
  • What causes them?!
  • Confirming a resonant condition bump test / impact test (2-ch, hammer & accel) / run-up / coast-down / bode Nyquist plots
