I need a set of stator currents of synchronous machine in an unbalanced mode. How can I get the unbalanced mode?

The voltage supply equations can be changed to induce current imbalance. Suppose you are applying 3-phase voltage to the system Like Vs Sin(ωt), Vs Sin(ωt − 2π/3),Vs Sin(ωt + 2π/3), change one phase voltage to (Vs-V0) Sin(ωt) and rest same, then change other/two phase voltages.. This will induce voltage imbalance and that will further induce current imbalance.

Anuj.. Can you please tell me why I should use only 400 volts and not 133.3?

Its a simple convention for a 3-phase supply, when you supply a 3 phase winding, you do apply a peak voltage Vm to each of the three phase, not Vm/3.
