e-NVH in home appliances

Home appliances can involve electromagnetically-excited noise and vibrations, including noise of electric motors.

More generally consumer goods contain numerous electronic systems. They operate close from the users, in a low background noise environment. Their so-called electrical hum or buz can therefore be heard more easily and may result in acoustic annoyances.

These products may include:

- compressors for refrigerators
- electric motors for washing machines, cooking robots
- heating and ventilation (HVAC) electric motors
- electrified curtains electrical motors

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.
