The armature voltage control of D.C. motor provides
A)constant voltage drive
B)constant current drive
C)constant torque drive
D)none of the above

Question

Quizplus · Accepted Answer

Armature voltage control of DC motors is used to provide a constant torque drive. By varying the voltage applied to the armature, the speed of the motor can be controlled while maintaining constant torque, assuming the motor is operating in a linear region below its base speed.
