How to implement noise reduction techniques of electric motors in MANATEE?

Objectives

This article shows how to use MANATEE software dedicated to the NVH calculation of e-machines to implement noise reduction techniques in electric motors.

Principle

The following main noise reduction techniques are available in MANATEE:

Validation cases

EOMYS has analyzed the NVH behaviour of more than 60 electric powertrains and obtained up to 40 dB reduction after redesign.
