convergence issue

Please login with a confirmed email address before reporting spam

I am designing a 3phase sq cage induction motor. Initially I have excited the coils with current source and the model was working fine. But When I removed the current source and excited the coils with electrical circuit consisting of 3ph voltage source, end winding resistance and reactance the time dependent solver is not converging even with automatic highly non linear(newton) method. Can any one suggest me how to deal with this convergence issue, what changes can be made to the solver configuration.I am using Time dependent solve.
