  6. commutator
    Device in a DC (direct-current) electric motor that reverses the current flowing in the armature coils as the armature rotates. A DC generator, or dynamo, uses a commutator to convert the AC (alternating current) generated in the armature coils into DC. A commutator consists of opposite pairs of con...
