e-NVH in medical appliances

Electrical systems involved in medical appliances must be particularly quiet. They can be source of parasitic vibrations during surgery operations, as well as acoustic annoyances during stay in hospital.

As an example, the following electromechanical systems can vibrate and create unpleasant acoustic noise due to electromagnetic forces:

  • high speed spindle motors used for surgery
  • dental drills
  • ventilatory support machines
  • pacemakers
  • motorized exoskeletons
  • centrifuges in laboratories

Manatee simulation software allows to control the noise level of these components during their whole development cycle, from early design stage to system-level detailed design stage, including specialized e-NVH analysis and mitigation tools.

Complementary to Manatee, EOMYS Engineering can characterize vibro-acoustic issues with advanced electrical, vibration, acoustic and sound quality measurements, and implement suitable electrical, control or mechanical solutions. Regular technical trainings on e-NVH are also provided for electrical engineers, mechanical engineers, acoustic engineers and NVH test engineers.
