    I'm having troubles calculating torque (excitation and cogging torque).
    The model represents an axial flux machine. Central section is the
    stator and lateral pieces are rotors with PM. In order to, reduce the
    problem I only work with a one-pole section. I used lua scrip to
    evaluate the cogging torque for different position (in one slot pitch).
    However I'm not sure how to calculate resultant torque when current is
    circulating by the winding. How do I have to define the line in order to
    obtain stress tensor torque?

    Any help is welcome

    Juan A.
