Radial airgap flux comparison (FEMM vs Permeance/mmf)

One can see that the fast reluctance network model of MANATEE for interior permanent magnet machines correctly estimates the open circuit flux density waveform when compared to FEMM. However the reluctance network is not able to estimate the tangential airgap flux density, which can influence the NVH behaviour of the electric powertrain. The tangential flux density can be modeled using subdomain modeling technique as shown in the tutorial tuto_IPMSM_12.
