Manatee offers a collaborative simulation and analysis environment designed to quickly and accurately optimize the vibroacoustic performance of electric machines and drives under electromagnetic excitations. Its user-friendly interface has been developed for control, electrical, mechanical and NVH engineers. Designing high-quality electric machines requires controlling their acoustic noise and vibration levels at every development stage, from risk analysis in preliminary studies to vibroacoustic troubleshooting after prototype manufacturing. Electric machines can induce significant electromagnetic noise and vibration (e-NVH) due to Maxwell force excitations, resulting in sound levels going up to 125 dBA at 1 meter. All topologies of electric machines can produce health, comfort, environmental friendliness or mechanical fatigue. Electrical, magnetic and mechanical early design choices can have up to ±20 dB...
