The commutator

Explanation:

The commutator in a D.C. Motor is a pair(or more) of half-shells wrapped around the shaft of the armature and connected to the power source through the brushes. Each half turn of the armature causes the brushes to contact a new split ring, reversing the direction of current flow through the armature windings, which reverses the polarity of the electromagnetism produced in the armature.
