How to find armature resistance in Ansys Maxwell adjustable speed permanent magnet synchronous generator. anyone can help me out?

why the torque versus angle characteristics for motoring mode and generating mode is asymmetrical?

Hi @ sirvinFor computing winding resistance and inductance you can run an eddy current simulation.nDon't forget to assign inductance matrix.nRegarding your next question - why there is a difference in torque. I may need more information to comment on.nProvide us with some screenshots of your model, excitatio,n, and analysis setup.nnRegardsnNavyann

For Phase-A supply voltage is 4.08237*sin(2*pi*500*time-2.32015*pi/180)nFor Phase-B supply voltage is 4.08237*sin(2*pi*500*time-2.32015*pi/180-2*pi/3)nFor Phase-C supply voltage is 4.08237*sin(2*pi*500*time-2.32015*pi/180-4*pi/3)nWhenever I find the torque versus angle characteristics by assigning the parameter theta in Motion Setup's Initial condition $thetanand theta varies from 0 to 180 degrees for 4 pole machine I got asymmetrical torque versus angle characteristics for motoring and generating mode.n
