NVH Simulation of Electric Machines: From Concept Design to Accurate Acoustic Noise Prediction

Noise Vibration and Harshness (NVH) is an important design criterion for many applications where electric machines are involved from medical devices, to electrified mobility and household appliances. Due to complexity and the nonlinear coupled physics governing the magnetic and structural behavior of these systems, combined with various noise sources, the level of acoustic noise in applications is not easy to predict without proper modeling and simulation.

In this presentation:

• We will show you how to leverage Ansys tools solutions to accurately predict the acoustic noise generated by electric machines.
• NVH performance consideration for a permanent magnet machine from concept design to sound prediction will be presented.
• Tools Ansys solutions and workflows used to design a quiet electric machine will be demonstrated step by step.
