Quizplus · Accepted Answer

When the field of a DC shunt motor is opened, the field current drops to zero, drastically reducing the field flux. Since the speed of a DC motor is inversely proportional to its field flux (according to the motor's speed equation), a significant reduction in field flux causes the motor to speed up to a dangerously high level, potentially causing damage.

If the Field of a D
