Starter Commutator for Auto DC Motor Components

Starter Armature Commutator

The Starter Commutator is suitable for automobile starter. It is found in the back of the motor's housing and forms part of the armature assembly. Usually round and segmented, its main function is to transfer current to the armature in the required sequence. That is made possible by the segments or copper bars on which the motor brushes slide.

Each segment or bar on the commutator conveys current to a particular coil. To enhance efficiency, the contact surfaces are made from a conductive material, usually copper. The bars are also separated from each other using a non-conductive material such as mica. This helps prevent shorting.
