A common method of controlling the speed of ____ is to connect impedance in series with the stator winding.
A) servo motors
B) brushed DC motors
C) brushless DC motors
D) small AC motors

Question

Quizplus · Accepted Answer

Small AC motors are commonly controlled by connecting impedance in series with the stator winding. This method is known as series impedance control and it reduces the amount of current flowing through the stator winding, resulting in a lower magnetic flux and a decrease in the motor speed.
