A DC servo motor produces 10 milli N-m torque (Tm) with current (im) of 0.25 A with a DC supply (vm) of 20 V. The terminal resistance of the motor (Rm) is 8 Q. What is the torque constant k, of the motor? If the back-emf constant km is the same as the torque constant, wha is the back-emf at this condition? What is the speed of the motor in rotations per minute? Assume that the motor operates at steady-state: im(t) = im and Wm = Wm: (1)
