A commutator is an apparatus that reverses the direction of electrical current. It has many uses, including: DC generators: The commutator converts alternating current (AC) into direct current (DC). It also ensures that the current always flows in one direction. DC motors: The commutator reverses the current direction between the external circuit and the rotor. It also produces torque by changing the direction of current within the revolving windings every half turn. Universal motors: The commutator is used in universal motors. The word "commutator" comes from the Latin word commutare... Show more A commutator is an apparatus that reverses the direction of electrical current.

However, they have some limitations, including: Sparking and wear: The brushes that slide across the commutator can cause sparking and wear, which can reduce the efficiency and lifespan of the machine.
