12. (80 pts) The internal resistance of the DC motor shown below is 192. The motor's internal mass moment of inertia and damping are J-2 kg-m, and D-2 N-m/(rad/sec). The motor damping are J2 = 18 kg-m², and D2 - 36 N-m/(rad/sec), 0, and 0are the angular displacements of the motor and the load. a. The torque-speed curve is for the applied input voltage ea - 50 V. Find the torque constant K, and the back EMF constant kb. T (N-m) b. Find the total mass moment of inertia of the 100 motor-load system Jm. 50 V c. Find the total damping of the motor-load syste D. d. Find the transfer function of O.(s)/E.(). e. Find the transfer function of (s)/E.(S), 150 00 (rad/s) Ra +-W eat) N = 50 Adll) Di = 2 N-m-s/rad Ovi = 2 kg-m2 OL(1) Of N2 = 150 ot 012 - 18 kg-maf D2 = 36 N-m-s/rad
