Good afternoon

After doing a transient analysis, I obtained the winding currents and the id and iq currents, but even though the winding currents are as I set them, the dq axis isn't recording anything. Is there a particular reason for this?

Hi @Gad_Lad_1 nPlease provide more information on which machine are you analyzing? Which Ansys tool are you using? is it in 2D or 3D simulation?nWhat is your setup? nHow are you setting up the model - is it by importing a dxf / 3d CAD model and setting it up manually or you using RMXprt to create the Maxwell design?nAdd additional screenshots for us to understand where the problem is.nnRegardsnNavyann

Have you created the 2D model from RMXpert? For which Id and Iq expressions are automatically written.nOR are you writing expressions for id and iq in output variables?nIs it an IPM machine?nIf you do not provide sufficient information it will be very difficult to figure out where the issue is.nnRegardsnNavyan

It was made in RMxprt first, and the motor is an IPM motor. Id and Iq are not written as output variables.n

I analyzed an IPM motor in 2020R2 (Maxwell model created from RMxprt) . I didn't face this issue.nCan you try analyzing an example IPM model and check if you face the same issue?nAlso, check the design sheet for your model in RMXprt for any clues from the results.nWhich version of AEDT are you using?.RegardsnNavyan
