How can add fault to the circuit of DC machine?

I have the model of dc machine. I would like to know how can I unbalance it. Also, I want to read the values of Te and Ia in balanced condition and unbalanced condition to detect its condition. Please help me in this. Thanks in advance.

You can add impedance on a single line, add controlled sources, short one of the phases to ground with an ideal switch. There are many other options as well.
