D)all of the above methods

Question

Quizplus · Accepted Answer

Speed control of a universal motor can be achieved through various methods including varying the field flux with tapped field windings, connecting a rheostat in series with the motor, and applying variable voltage using silicon controlled rectifiers (SCRs). Each of these methods adjusts the motor's speed by altering the electrical input or the motor's internal electrical characteristics.
