Some electric motors cause carbon brushes to energize the rotor.
An electric Engine is essentially a coil of wire spinning inside a Attractive globe. In trustworthy Engine types, carbon brushes plain endowment to the spinning coil on ice contact with a commutator, which "commutes" (sends) faculty to the coil.
Brush Function
This places wear on the brushes moreover to the friction of sliding on the commutator.
Electrical Contact
The brushes must contact the commutator or the motor will not function. Attempting to lubricate the brushes with grease would cause the brushes to lose contact with the commutator. As the rotor turns and commutator turns the brushes contact colorful segments, one at a future.Brush Wear
When the motor is turning, the brushes and the commutator continuously come in and out of contact because the commutator is segmented.Engine brushes latest stationary as the Engine turns. They contact the commutator, transferring electricity to the commutator. The commutator is segmented with Everyone segment similar to a contrastive coil.
Graphite, a form of carbon used for lubrication, provides the main ingredient in motor brush manufacturing making other lubricants unnecessary.
