Quasi-static variable speed e-NVH calculations

Manatee variable speed e-NVH feature automatically runs several electromagnetic and vibro-acoustic calculations at variable speed with specified control strategy (e.g. Id/Iq as a function of speed).

Once calculation is done, graphical post-processing are naturally extended to variable speed. These post processing include:

  • current as a function of speed
  • force harmonics as a function of speed
  • magnetic force, vibration and noise waterfalls and Order Tracking analysis
  • overall levels as a function of speed (e.g. Sound Power Level or Sound Pressure Level)
