The speed of a shunt motor can be controlled beyond its rated value by changing the amount of voltage across either the field or the armature winding.

Question

Quizplus · Accepted Answer

The speed of a shunt motor can be controlled by varying the voltage across its field winding to change the field current, or by adjusting the voltage applied to the armature winding. Reducing field current or increasing armature voltage can increase the motor's speed beyond its rated value.
