A dc shunt motor drives an elevator load that requires a constant torque of 300 N m. The motor is connected to a 600 V dc supply and the motor rotates at 1500 rpm. The armature resistance is 0:5 Ω.
(a) Determine the armature current.
(b) If the shunt field flux is reduced by 10%, determine the armature current and the speed of the motor.
