I designed a circuit like below in external circuit excitation.When I calculate according to the datas I got from the analysis, I find the stranded loss value different from the stranded loss value shown by the program.November 18, 2020 at 2:59 pmicellb1Ansys EmployeeHi, Array ,
Is there a Maxwell project to which this external circuit is linked? If so, could you share some info about the Maxwell project and maybe some screenshots about the 6 windings in Maxwell? Thank you.

The strandedloss shown in Maxwell result is calculated based on the winding in the Maxwell side, the resistances added in external circuit are extra resistances which would not be included in the R for loss calculation in Maxwell. Since you are using current source in external circuit, the resistances value would not even affect loss calculation. If you use voltage source in external circuit, the resistance would change the current input in the Maxwell project and thus affecting the loss.

I still can't get it.
@icellb1 says that the resistances in the external excitation circuit are not considered in the calculations that the software does for the stranded losses.
Ok, thank you for this clarification, but still, the stranded losses were analytically calculated and found =6000 W. And the software finds the stranded losses = 5000W.
Does that mean that the software calculates the resistances of the windings to be less than the analytical values?
For example, the analytical value of the HV winding of phase A = 30 ohms, but the software calculates it to be 25 ohms.
