Assume this motor has no friction. 1) (10 points) I have a DC motor with a torque constant KT of 2.0 Nm/A. I am driving it with 10V. At stall speed, it has a coil resistance of 0.2. What is the stall torque? 2) (10 points) Using the same motor at 8V, what is the rotational speed (in rad/s) that corresponds to a torque of 60 Nm? 3) (10 points) How much power is produced by this motor at the speed and torque from question 2? 4) (10 points) What is the efficiency of this motor at 28.65 RPM with a load of 10Nm
