Results

This validation case compares the radial airgap flux computed by the 3 magnetic models of MANATEE (permeance/mmf, subdomain, FEMM) for skewed machines for the 2 skew computation methods:

  • type_skew=1: average flux along the axial direction
  • type_skew=2: full 3D flux density

3 machines are used, one with no skew, one with a skewed stator and one with a skewed rotor.

type_skew = 1 validation
type_skew = 1 validation
type_skew = 2 validation
type_skew = 2 validation

One can see that the three methods are consistent. Subdomain modeling technique is recommended as it captures both radial & tangential flux components.
