Axial flux permanent magnet generator

Hi Dr. Ivar/All,

Iam trying to simulate the axial flux permanent magnet generator with two rotor and a coreless stator sandwiched between two rotor.

Permanent Magnets are attached on inner surface of the rotor in such a way that magnets on two rotor are in N-S orientation.

I used the following boundary condition for the different domain under rotating machinary physics(rmm)
- For PM i used the constitutive relation remnant flux density from the Amperes Law
- For two rotor i used the BH realtionship
- I used the multi turn coil domain to model the coil
-used the prescribed rotational velocity for the rotation fo the rotor
-used continuity

Apart this i used the free tetrahedral meshing .

I tried to simulate taking reference from the generator model in Comsol model library but still not getting the desired flux and the voltage.

I really need your suggestion regarding this matter.I tried to find out the discussion regarding the axial flux permanent magnet generator in the discussion forum but none of them are answered. I am stucked at this point please help me out .

I have attached the model by clearing all the mesh and solution for making it appropriate for uploading.

Thank you
Aruna
