Call for value of a variable in one mfile to another mfile

I have a mfile named motor_model.m. I have another mfile named controller.m where I am calling motor_model.m in the first line. Now the output of motor_model.m is the steady state current which is stored in a vatiable named I_steadystate whose value needs to be called in controller.m. Could you give me the code as to how I can do this?
