Question

Quizplus · Accepted Answer

The speed of a shunt motor can be controlled by varying the armature current, varying the field current, and varying the voltage across the field winding. All these methods affect the motor's speed by altering the magnetic flux or the current in the circuit, which in turn changes the speed.
