How to setup the number of slices Nskew_slices?

The 3D electromagnetic simulation (e.g. case of axial eccentricity, or skew) requires to define the number of slices along the axial direction. This variable is defined in the simulation project by


In case of magnet stepped skew it is recommended to set the number of skew slices to the number of magnet segments.

In case of linear skew of a lamination the number of skew slices should be above 5. The validation case NUM_006 shows the effect of the number of skew slices on the variable speed acoustic noise.

In case of axial eccentricity (diagonal eccentricity) a minimum number of 10 skew slices is recommended.
