Electromagnetic semi-analytical module for surface permanent magnet machines (EM2.SPMSM)

Subdomain semi-analytical model for the prediction of the closed circuit airgap radial & tangential flux density due to surface magnets in radial flux PMSM (internal rotor, parallel or radial or Hallbach magnetization).

The model assumptions are
- surface permanent magnet inner rotor synchronous machine
- radial edges for magnets and stator slots, and stator slot openings
- cylindrical bottom for magnets and stator slots (fully polar geometry)

The module calculates the magnet field with comp_SDMsurfPM script and the armature field using comp_SDMarmature script.
