A 200-VDC shunt motor with an armature resistance of 0.1 Ω and a field resistance of 100 Ω draws a line current of 5 A when running with no load at 955 rev/min. Determine the motor speed, the motor efficiency, the total losses (i.e., rotational and I 2R losses), and the load torque (i.e., Tsh) that will result when the motor draws 40 A from the line. Assume rotational power losses are proportional to the square of shaft speed.
