Hi HDLI Thanks a lot for your suggestions. I understood what you said.
Now, if I want to put a sinusoidal load torque, is there any way out to do so by changing current/phase angle?
I opened up a discussion here: https://forum.ansys.com/discussion/comment/121479#Comment_121479
What we expect is electromagnetic torque should also have followed a sinusoidal pattern.
However, electromagnetic torque produced is still a horizontal straight line.
Could you please suggest where am I going wrong ?
