Carbon Brush

To create contact between a stationary wire and a revolving rotor, carbon brushes are utilised. DC motors are used the most frequently. Every half cycle, the direction of current flowing through the rotor winding must be reversed in order to maintain torque in the same direction throughout the revolution. Commutation, as it is known, is accomplished by feeding the rotor current through brushes. The copper plates attached to the rotor are connected to the brushes, which are mounted to the stator. The brushes deliver electricity in the desired direction when the rotator spins.

By moving across the commutator bars, the brushes are what allow current to flow to the armature. Like a battery, the brushes are linked to the power source. The brushes must glide across commutators bars, which are copper segments attached to the coils of the armature in the motor since the armature twists and rotates and we must generate a revolving magnetic field. The magnetic field that rotates the motor is created by coils inside the armature. The Armature, the central portion of the motor that pushes or pulls utilising the magnetic field that all electric motors need to spin and produce power, may include magnets on its outside portion or another field coil.
