E-NVH: Acoustic noise and vibrations due to electromagnetic forces in electrical machines

E-NVH: Acoustic noise and vibrations due to electromagnetic forces in electrical machines

 

e-NVH Training EOMYS

The objectives of the full technical training (3 days) are the followings:

  • understand the phenomenon of audible noise and vibrations due to magnetic forces in electric motors,
    mainly Permanent Magnet Synchronous Machines used in automotive applications, including its impact
    on sound quality;
  • identify the root cause (e.g. winding, slotting, PWM) of a given vibration or acoustic noise harmonic based
    on experimental data interpretation and / or numerical simulation;
  • find some mechanical and electrical solutions to mitigate noisy electromagnetic force harmonic;
  • know the main numerical simulation challenges of e-NVH, and how to include noise due to
    electromagnetic forces in its current CAE workflow;
  • design an NVH test campaign to characterize the vibroacoustic behaviour of an electric motor under magnetic forces, and troubleshoot electromagnetic noise and vibration issues.
