Commutator
A commutator converts alternating voltage into direct voltage.A commutator is a cylindrical structure built up of segments made of hard drawn copper.These segments separated from each other and from frame by means of mica strips.These segments are connected to the winding by means of risers .The risers have air spaces between one another or that the air is drawn across the commutator there by keeping the commutator cool.The components of a commutator is shown below
The general appearance of commutator when completed and commutator and armature assembly is shown below.
