Electromagnetically-excited noise and vibrations in industrial applications

In industrial applications, noise can be dominated by electromagnetically-excited noise and vibrations, and more especially noise and vibrations of electric machines. This can represent a health issue (e.g. workers working close to electric machinery) or a comfort issue (e.g. elevator motor noise annoying local people).

Noise and vibrations due to magnetic forces can be present in the following applications:

- high power pumps (e.g. chemistry, oil & gas)
- high power motors (e.g. mining, cement factories)
- reciprocating compressors, scroll compressors
- traction motors (e.g. elevators, conveyors)
- high power transformers

EOMYS characterizes these vibroacoustic issues with specialized electrical, vibratory and acoustic measurements, proposing both electrotechnical, mechanical and acoustic solutions.

EOMYS also works at design stage helping the electrical engineers to assess the NVH performances of these components (for instance with MANATEE software), and realizing technical trainings on the control of magnetic noise and vibration.

    There are differences between sound parameters we measure physically and the sound perception we have as humans. For instance, we are used to describe the loudness of a sound using the Decibel scale. But how to explain that two sounds  (...)
