This all depends on how you define your motor. Technically no motor has a no load speed since the motor has to spin itself which takes some power input. Since the CIM has a resistance and you have to put power in which means that your producing power somehow. I think you could define the whole drive train as a motor, maybe a linear motor, and then say that the top speed of the robot is the free speed.
A lot of solving a problem in physics is just choosing the correct frame of reference and it might be easier to define the drive train as the motor and just measure its speed. I'm not sure what the use of this is but hey...
