Optimize Electric Machine Noise and Vibration Virtually

Manatee – Fast, Accurate Vibroacoustic Simulation for e-NVH Design



Overview

Manatee is a collaborative simulation and analysis tool that helps engineers quickly and accurately optimize the vibroacoustic performance of electric machines and drives under electromagnetic excitations. Its easy-to-use interface supports control, electrical, mechanical, and NVH engineers.

Controlling noise and vibration is essential at every design stage, from early studies to prototype testing. Electric machines can create high electromagnetic noise and vibration (e-NVH) due to Maxwell forces, sometimes reaching 125 dBA at 1 meter. These effects can impact comfort, durability, and environmental performance.

Early design choices in electrical, magnetic, or mechanical aspects can change noise and vibration by up to ±20 dB. Since prototyping is expensive and slow, Manatee’s virtual prototyping environment improves productivity, provides valuable insights, and helps achieve better vibroacoustic and electromagnetic performance in less time.
