Backed with >8 years of consulting experience in solving noise and vibration issues in electrical systems, EOMYS Engineering has developed Manatee software solutions to speed up the development of low-noise electrical systems and reduce the number of prototypes produced and tested during the development phase. 

The first version of this software, named Manatee V1, has been mainly used by EOMYS R&D Engineers to support their analysis of more than 150 e-machines covering all topologies and applications, from 10 RPM to 100 kRPM speed and from 10 mm to 10 m diameter.

Manatee vision is to become the entry point for all engineers involved in the design & validation of electrical systems with NVH requirements. It can be used as a standalone multiphysic software, but can also be smoothly integrated into existing CAE software to assess vibro-acoustic risks all along the development lifecycle.
