What is the difference between MANATEE and other electromagnetic FEA software suite?

MANATEE is the only software providing a fast and accurate computation of noise & vibrations due to 3D Maxwell forces in radial flux electrical machines: variable speed calculation time on a standard laptop varies from a few seconds to one minute including commutation effects up to 20 kHz.

MANATEE can naturally be used in basic design phase, to evaluate NVH behavior during early electromagnetic design loops (e.g. different slot/pole combination, different topologies), but it can also be used during detailed design phase, using Electromagnetic Vibration Synthesis coupling with structural FEA such as Optistruct, and after manufacturing as a diagnosis tool to identify and tackle magnetic noise & vibrations issues. MANATEE can also help electric machine designers specifying manufacturing and assembly tolerances to have a better control on vibration and noise levels.

MANATEE contains advanced vibroacoustic post processing tools to help the electric machine designer understand the root cause of magnetic noise & vibrations and run appropriate noise mitigation actions (e.g. slot number change, pole shaping, current injection, skewing, notches).

Contrary to available electromagnetic FEA software (e.g. Flux, Maxwell, Jmag, Magnet) MANATEE built-in semi-analytical models do not suffer from high mesh sensitivity issues when assessing vibration and noise. Contrary to multiphysic FEA software suites (e.g. Ansys Workbench, Comsol Multiphysics), the multiphysic process of MANATEE is already defined and all physics are seamlessly coupled.

The tutorial on Prius PMSM machine shows that MANATEE simulation can give in a few seconds the same conclusions as a complex FEA model under Ansys. MANATEE electrical, electromagnetic, structural and acoustic models have been validated extensively. The validation page contains hundred of validation cases, but you can have a look to our webpage dedicated to industrial experimental validations.
