The problem is that we want to replace the old stepper motor with a new   
   stepper motor and we are trying to build an argument that new can replace the   
   old one because their speed vs torque curves are same. Is this the right way   
   to prove?   
      
   We do not have any information about the acceleration and deceleration of the   
   old stepper motor.   
      
   if we compare the speed vs torque curves and if they turned out to be same   
   then would it be okay to conclude that the acceleration and deceleration of   
   the two motors will be same?
