Hello,

Â

Thank you for your reply.Â

2. I run the model at no load (0 current) and then check the flux linkage and induced voltage. According to the Ansys document, the alignment angle is the angle at which, the Phase A flux linkage has max lower value as well as the induced voltage for Phase A crosses 0. I do the same, and put this angle in the rotation mechanical angle for the load analysis but I dont get the max torque. I am not sure what seems to be the problem?Â

This is the method to align the rotor pole to the stator pole, it only gives the initial angle that aligns the poles to use DQ transoform. You need to find the Max torque angle/phase after that. - Aligning rotor pole with stator pole, does that mean aligning phase A axis with d-axis?

I am not sure what do you mean by correct result. To get max torque, we usually set the speed at 0, then run with sine current to find at which time point the torque reaches the max value, and use the phase at that time point as the initial current phase. - I dont fully understant this method. Could you please elaborate?Â

Thank you very much.
