Machine
This validation simulates a machine that can be found in the article : L. J. Wu, Z. Q. Zhu, D. Staton, M. Popescu, and D. Hawkins, “Subdomain Model for Predicting Armature Reaction Field of Surface-Mounted Permanent-Magnet Machines Accounting for Tooth-Tips,” IEEE Trans. Magn., vol. 47, no. 4, pp. 812–822, 2011
This SPMSM (Surface Permanent Magnet Synchronous Machine) has 12 stator slots for 4 poles pairs (12s/8p). 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).
This analytical model is accurate enough to enables a first design optimization of an SPMSM.
