pm axial flux cogging torque

Recommended Posts

Hi, I'm having trouble with my simulation
Firstly,  import cad from solidworks , and then I use a axial flux example of alteir flux!
My problem is the flux density is  about zero
I do everything right, but Result not true

After checking the Flux project, the problem come from the affectation of the volume region ‘magnet_s and magnet_N’. For example when I try to select the volume region ‘magnet_N’, this lead to select all the magnets volumes (magnet_N and magnet_S at the same time). I think for this reason you get a very low value of the flux density after solving the problem. Correcting this problem, I get a correct isovlaues of flux density.

You will find attached the Flux project ready to mesh and solve. Other thing you need to compute the period of cogging torque if you want to get the correct shape of the curve.


Best regards.
