Nov 2018: MANATEE webinars, e-NVH training, Synchronous reluctance machines

Webinars on MANATEE software

New webinars will be organized by EOMYS in January and February 2019 to present MANATEE software latest features. In particular, the webinars will deal with the variable speed NVH design of e-motors under electromagnetic excitations. Registration can be done through our webinar webpage.

E-NVH technical trainings

There are still some places available to attend to our technical training session on electromagnetic Noise, Vibration, Harshness (e-NVH) held in English in Bristol (UK) and in our office in Lille, France (1 hour from Paris). All training dates, content, and registration details are available on EOMYS training webpage. The training is suitable for both NVH engineers and electrical engineers.

Ongoing MANATEE developments

PNG - 58.7 kb
  • Synchronous reluctance machines: MANATEE electromagnetic models (coupling with FEMM and fast permeance/mmf model are being extended to SyRM, a topology that is increasingly investigated in automotive electric powertrains
  • New Frequency Response Function format: MANATEE FRF are being extended to all outer yoke points (instead of RMS average velocity in radial direction) to perform additional post-processing after calculations, in particular Operational Deflection Shapes
  • Coupling with Nastran/Actran: MANATEE can already provide magnetic forces in .unv format, it is now being coupled more specifically to Nastran and Actran from MSC software.
  • New template for e-NVH maps: a third template to specify control parameters in torque/speed plane is being added. MANATEE unique noise map feature allows to quickly predict the NVH behaviour of the electric drive over its fourth quadrant of operation.

Conference and events

After three years of work, our PhD student E. Devillers is defending his industrial PhD entitled "Electromagnetic subdomain modeling technique for the fast prediction of radial and circumferential stress harmonics in electrical machines" on 13th December 2018 at Ecole Centrale Lille, France, 14h CET.
