The motor that does not contain a wound armature, commutator, or brushes is the _____ motor.
A) servo
B) stepping
C) selsyn
D) brushless DC
Brushless DC
A type of direct current electric motor (DC motor) that uses an electronic controller to switch the current in the motor, eliminating the need for brushes.
Wound Armature
A component in electrical machines consisting of coils wound around an iron core, which rotates in a magnetic field to induce electromotive force.
Brushes
Sliding contacts, generally made of carbon, used to provide connection to rotating parts of machines.
