Hi,
I am simulating a 3D SPM motor, but the cogging torque is not periodic. The cogging torque period should be 2 deg, as the 2D sim confirmed.
Attached the 3D model.

Youi will find attached a pdf file explain how to mesh the air gap to get a periodic cogging torque. This document is available in Altair connect. To get it:
Connect to Altair connect
Select : documentation
In search put: flux cogging torque
Best regards.
