A separately excited dc motor has the following parameters: 220 V, 10 A, 1,400 rpm, armature resistance= 2.3 Ω, field excited at rated current. When the armature is open-circuited and rotated at 1,500 rpm by a prime mover, the armature voltage was 250 V. If the motor is now supplied at rated voltage and if it carries 5.6 A armature current, what will be the approximate load torque on the shaft?
