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

Question

Quizplus · Accepted Answer

The armature voltage control of a DC motor adjusts the voltage applied to the armature. By varying this voltage, the speed of the motor can be controlled while keeping the torque constant, as torque is directly proportional to the armature current, which remains constant if the load does not change.
