Dec-Jan 2019: FEMM/DXF import, SynRM/SRM, e-NVH trainings

EOMYS completed its 100th consulting project

After 5 years of activities, EOMYS engineering team recently completed its 100th consulting project. The company has now more than 70 customers worldwide and has some e-NVH experience on more than 100 different electric motors, from 5 rpm to 150 krpm speed, 10 mm to 10 m diameter, 5 W to 50 MW power ranges - All noise troubleshooting analyses having started with a MANATEE e-NVH simulation.

Ongoing MANATEE developments

Next release of MANATEE software for the fast e-NVH simulation of electric motors will include some important updates and new features such as:

  • .dxf import for stator or rotor geometry in MANATEE coupling to FEMM.
  • .fem model import in MANATEE coupling to FEMM.
  • FEMM mesh optimization and implementation of sliding band technique to reduce the computing time and numerical errors.
  • Modelling of Synchronous Reluctance Machines (SynRM) and Switched Reluctance Machines (SRM).
  • Calculation of tooth Frequency Response Functions to ease the import of experimental FRF.
  • New slot shapes particularly dedicated to SynRM and SRM topologies.
    New slot type for MANATEE 1.08.01

    Several post processing have been improved, such as order tracking analysis and waterfalls.
