LOOKING FOR A COMPREHENSIVE SOLUTION FOR YOUR E-NVH CHALLENGES? 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. A COMPREHENSIVE E-NVH TESTING SOLUTION Instrumentation Acquisition focused on your needs Software e-NVH measurements & analysis Electric motor Services From training to consultin

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. The solution goes all the way to provide a full range of high-end acquisition and analysis instrumentation. e-NVH environment • anagement of your EV motor M topologies (PMSM, SCIM…). • re analysis of the main excitations P (frequencies, wavenumbers). Electric Markers Based on motor and converter electric characteristics, e-NVH excitations can be spot...
