Machine
This validation simulate a machine that you can find in the article : Lubin, S. Mezani, and A. Rezzoug, “2-D Exact Analytical Model for Surface-Mounted Permanent-Magnet Motors with Semi-Closed Slots,” IEEE Trans. Magn., vol. 47, no. 2, pp. 479–492, 2011.
This SPMSM (Surface Permanent Magnet Synchronous Machine) has 6 stator slots for 2 poles pairs (6s/4p). The airgap field computation is done by a permeance and mmf model (Magnetomotive Force) along the airgap.
Stator slots are filled with Single layer non-overlapping windings with "alternate teeth wound", creating armature field.

Results
The permeance and mmf model implemented on MANATEE is compared with the FEMM model in the figures below. (See the different Electromagnetic Modules).
- Radial airgap flux (Femm vs Permeance/mmf)
This analytical model is accurate enough to enables a first design optimization of an SPMSM.
