smr_su_indicazioni.msim why the torque is zero?

How wired icon of motor to icon of sources?thanks

How I can solve it for P?

P=i^(2)r+(ⅆ)/(ⅆ t) (1/(2)l(tetha)i^(2))+1/(2)i^(2)(ⅆl(tetha))/(ⅆ theta) w

attach i(t) "corrente", l(t) "induttanza", theta "angular", w "rotary speed"graph of funtions

thanks

sol_L := dsolve({de_L, ic});

    {x(t) = (-y0 - x0) exp(-2 t) + (y0 + 2 x0) exp(-t),
      y(t) = -2 (-y0 - x0) exp(-2 t) - (y0 + 2 x0) exp(-t)}
How i can plot this?thanks
