A four-quadrant separately excited DC motor is powered from a 100 V battery using a bipolar PWM converter. The field current is kept constant and the armature resistance is 0.6 Ω. When the converter is operating at a duty cycle of 0.8 and the armature draws a constant ripple-free current of 30 A, what is the back EMF developed across the armature?
