Mobius Vibration Analysis Category-II Certification Practice Test

Question: 1 / 400

What could be a consequence of having an unbalanced rotor on a machine?

Increased efficiency

Reduced wear on components

Excessive vibration

When a rotor is unbalanced, it generates centrifugal forces that lead to excessive vibration during operation. This imbalance results from uneven mass distribution around the rotor's axis, causing it to wobble as it rotates. The excessive vibration can have several negative effects on the overall machine operation, including increased wear on bearings and other components, potential misalignment, and structural fatigue over time. This can lead to unplanned downtime and maintenance needs as parts may fail or require more frequent servicing. The introduction of vibrations can also affect the overall performance of the machinery, potentially leading to a loss of efficiency and higher operational costs. Therefore, recognizing that excessive vibration is a direct consequence of an unbalanced rotor is critical for maintaining machinery health and operational efficacy.
