Case study: Vibration reduction in water pump motor with magnetically boosted Tuned Mass Damper

Problem description: A 75kW water pump motor experiences excessive vibration levels (up to 11mm/s RMS) due to the presence of a structural resonance in the mechanical supporting structure (see below). The frequency of this structural resonance lays in the operating range of the variable speed motor, leading to a significant vibrations amplification. The vibration measurements […]
