Definition of commutator in English:

commutator

noun ˈkɒmjʊˌteɪtəˈkɑmjəˌteɪdər

1An attachment, connected with the armature of a motor or dynamo, through which electrical connection is made and which ensures the current flows as direct current.
Example sentencesExamples
- The brushes conduct electricity to the commutator.
- He went on to build an electric motor in 1832 and invented the commutator, an integral part of most modern electric motors.
- One of the places you need them is in modern small motors which don't have a commutator.
- You can see that the commutator is simply a pair of plates attached to the axle.
- It may also increase efficiency of machines as there won't be frictional effects of brushes, commutators, etc, on the motor itself.
1. 1.1 A device for reversing the direction of flow of electric current.
  Example sentencesExamples
  The commutator must switch current to the correct drive magnets in the correct direction at the correct time in order to produce desired rotor movement.
  Note how the commutator reverses the current each time the coil turns halfway.
