Noise and vibration in electric motors can have several causes, including unbalanced rotors, misalignment, bearing defects, and electromagnetic forces. Identifying the source of these vibrations and finding effective solutions is essential for enhancing motor performance and reducing noise.

Key challenges:

  • Forecasting the production of acoustic noise
  • Minimizing structural born vibration
  • As one noise source is reduced, other sources become increasingly important
  • Determining the sound footprint of electric equipment under actual working conditions.
  • Avoiding mechanical resonance

By understanding the importance of noise and vibration in electric motors, engineers can apply Ansys simulation techniques to develop quieter and smoother-running motors, resulting in improved user experience and overall product quality.
