Abstract

This presentation illustrates the assessment of noise and vibrations of electric drives induced by electromagnetic forces with Manatee. A live simulation is first detailed, analyzing the main magnetic noise issues on an advanced reference case. As designing high-quality electric machines requires subsequent e-NVH levels control, a noise mitigation technique based on a rotor dual-notch is then investigated. Tradeoffs between electromagnetic performances and acoustic levels are explored through a parameter sweep. An optimized electric machine design is finally identified, emphasizing the value of tracking the e-NVH risks from the beginning of the industrial project.
