DC motor commutator is a crucial component of a direct current motor. It is a rotary switch that constantly changes the direction of current flow in the motor's armature windings, ensuring that the motor continues to rotate in the desired direction. The brushed motor commutator is typically made up of a series of copper segments connected to the armature windings. As the motor rotates, brushes make contact with the segments, creating a complete circuit and allowing the motor to operate efficiently. Without a properly functioning commutator, the motor would not be able to generate the necessary torque to power various applications, such as electric vehicles, industrial machinery, and household appliances.
