A separately excited DC motor has an armature Resistance of 1 Ω, the armature supply voltage is Va= 203 V DC. Initially the motor was running at speed = 677 rpm while supplied by the rated terminal voltage and the armature current = 10 A. While supplying constant torque, what is the speed of the motor if the terminal voltage is reduced to 128 V?
