Commutator

A commutator is a crucial component found in certain types of electric motors, specifically in DC (direct current) motors. It is part of the supply class Motors, Electrical, which falls under the supply group Electric Wire and Power and Distribution Equipment.

The commutator is responsible for reversing the direction of the electric current flowing through the motor's coils. It consists of a cylindrical assembly made up of multiple copper segments, known as commutator bars, which are insulated from each other. These bars are connected to the ends of the motor's armature coils.

As the armature rotates within the magnetic field of the motor, the commutator ensures that the current flowing through the coils changes direction at the appropriate time. This reversal of current allows the motor to continue rotating in a single direction, providing the necessary torque to perform mechanical work.

The commutator is a critical component in DC motors as it enables the conversion of electrical energy into mechanical energy. It ensures the smooth and efficient operation of the motor by maintaining the proper flow of current through the coils.

In summary, the commutator is an essential part of DC motors, which are classified under the supply class Motors, Electrical. It plays a vital role in the conversion of electrical energy into mechanical energy by reversing the direction of current flow in the motor's coils.
