A 16 kW, 220 V, dc series motor has its armature current equal to 86 A when the motor speed is 600 rpm. The armature resistance of the motor is 0.198 ?, and the field resistance is 0.l ?. The motor voltage can be adjusted by means of solid- state devices. The motor is to be used to lower a load by countercurrent braking (reversing Ea ) at an armature current of double the rated value, and at a speed of l0 rpm. Determine the terminal voltage required for this operation.
