what do you mean by the results are correct? are you referring to the static torque on the moving part when the currents phasis is zero?

yes but...

The dynamic torque is incorrect in the current excitation mode. Do you know what the dynamic torque problem is?

Something wrong with your model, the iteration process requires more time than usual. I suggest reexamining the meshing process by refining the airgap region instead of ferromagnetic parts. Don't forget also to set the force on the moving part using the parameter module.

Thank you Mr. Rebbah but I think the problem is something else .
