giratore.msim which error?I can't see V and I?thanks

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
