A commutator is built with a set of contact bars and is set into the revolving shaft of a DC machine allied to the armature winding. This is achieved using a conducting ring split in two, called a split ring or commutator. In a d.c. motor, a rectangular coil is placed in between the magnetic field and when current flows through the coil from the split ring commutator, a torque acts on the coil which rotates it continuously. This ensures that the torque continues in the same direction. If the armature has multiple coils, the commutator will similarly have multiple segmentsone for each end of each coil. Split commutators are rings that allow Direct current to move in the opposite direction to maintain a full rotation. Log in. These are made of hard copper so as to withstand the brush forces which are placed upon the . The ring divides from the centre into two halves.
