commutator Definition
- 1a device in an electric motor that switches the direction of the current as the rotor turns, ensuring continuous motion
- 2a segmented metal cylinder or disc that makes contact with the stationary brushes in a DC motor and conducts current to the rotor

Phrases with commutator
split-ring commutator
a type of commutator used in DC motors, consisting of two semicircular rings that are insulated from each other and mounted on the motor shaft
Example
The split-ring commutator is a common type of commutator used in small DC motors.
a type of commutator used in brushless DC motors, which uses electronic circuitry to switch the direction of the current instead of a physical commutator
Example
Brushless commutators are more efficient than traditional commutators because they have no moving parts.
one of the segments of a commutator that makes contact with the brushes in a DC motor
Example
The commutator bars were worn down and needed to be replaced.
Origins of commutator
from Latin 'commutare', meaning 'to change'
Summary: commutator in Brief
A 'commutator' [ˈkɒmjʊteɪtə] is a device in an electric motor that switches the direction of the current as the rotor turns, ensuring continuous motion. It is a segmented metal cylinder or disc that makes contact with the stationary brushes in a DC motor and conducts current to the rotor. The commutator is an essential component of a DC motor and can be of different types like 'split-ring commutator,' 'brushless commutator,' and 'commutator bar.'
