modelling end inductance and end resistance of an induction motor

Hi,

I am trying to model end winding resistance and end inductance of an Induction motor using electric circuit interface. My model works fine and produces good results when I keep only resistance with External I Vs. U . As soon as I connect with inductor, resistance and External I Vs. U 1, my model doesnot converge. Can any one suggest what is going on wrong here?

With best regards,
Gaurav
