Hello DELI, 

yes , we are using Externally excited synchronous machine(EESM). Initially, we simulate the model using- maxwell 2D. Now we are trying to compute same machine using 3D with same excitation patterm, same current values, same advance angle. in 2D i am getting positive torque, but in 3d i am getting negative torque for the same operating point condition
