HomeDC Motor MCQsWhen the ratio of back E.MF to applied voltage is ___ than the mechanical power develop by the shunt generator is maximum?Q. When the ratio of back E.MF to applied voltage is ___ than the mechanical power develop by the shunt generator is maximum?A. 1.0B. 0.5C. 2D. 3Answer: 0.5
A shunt motor is fitted with a field regulator for speed control. For constant torque load, the speed will be minimum when the resistance of the regulator is
