EV/HV NVH testing solution
NVH (Noise, Vibration and Harshness) of Electric Vehicles and Hybrid Electric Vehicles (EV/HEV) requires a wide range of dedicated applicated skills and high-end technology.
OROS proposes the most advanced and comprehensive solution to the challenges of e-NVH: testing software, services and Instrumentation. This solution has been developed in cooperation with EOMYS, who is a specialist of electromagnetic noise and vibration.

e-NVH signature of electric motors highly depends on motor topology, converter strategy, and structure-borne vs air-borne path contributions. Some specific tools are therefore required to quickly identify and solve e-NVH issues during testing.
- e-NVH environment
Management of your EV motor topologies (PMSM, SCIM…).
Pre analysis of the main excitations (frequencies, wavenumbers).
- Electric Markers
- Sound Design
The solution goes all the way to provide a full range of high-end acquisition and analysis instrumentation.
The portable and modular range from 4 to high channel count systems.
The Teamwork technology enables to cascade or distribute the instruments.
Solving NVH issues at design stage or after manufacturing requires complementary skills:
Including e-NVH measurements, test data analysis and problem solving.
NVH technical trainings
For NVH engineers, including application with OROS NVH testing system.
Focusing on your application.
