I referred to an example of PMSM motor available in *ExamplesTwin BuilderComponentsInterfacesMaxwellTR-TR2DJune 29, 2021 at 12:19 pmHDLIAnsys EmployeeJuly 5, 2021 at 2:54 amranjanpal999SubscriberHello HDLI Thanks a lot for your feedback. I shall apply the same.
The reason to set the sinusoidal function for inductance is to create an environment for changing load torque.
In one of my earlier posts, you had clarified that mechanical transient process could not be performed on PMSM motors. (https://forum.ansys.com/discussion/27747/load-torque-vs-transient-torque-for-pmsm-motor-coupled-with-vfd#latest)
Now, please consider following 2 points:
Inductance tend to change with change in current (https://www.researchgate.net/post/Does_the_inductance_changes_with_current_change_in_a_magnetic_circuit_containing_inductor_coil_resistance)
And, change in current is also an indication for change in load torque.
So, combining points 1 and 2, it can be said that, if inductance is a assumed as a sinusoidal function then, current will also tend to vary, which means load is varying.
Please let me know your views on this.
