This validation case deals with the extension of permeance/mmf model to interior magnet topologies. The rotor mmf is calculated with a single call to FEMM to be able to use permeance / mmf model in the case of interior magnets.

Machine

The machine is the one from the tutorial: machine_IPMSM_A (Prius case).

Interior Permanent Magnet Synchronous Machine (Prius 2004, automotive application)

Results

Radial airgap flux comparison (FEMM vs Permeance/mmf)
Radial airgap flux comparison (FEMM vs Permeance/mmf)

For higher accuracy the subdomain modeling technique can be applied as showed in the Prius tutorial.
