Carbon brushes for electric motors: indispensable for the operation of motors and equipments

Carbon brushes for electric motors are essential for the correct operation of these, as they create the electrical connection between the two main components; the fixed part and the rotor.

Carbon brushes for electric motors: indispensable for the operation of motors and equipments

The carbon brushes for electric motors have as objective to generate the correct operation of a machine or any motor that is electric; since they are manufactured according to each need.

It is a resource used in different industries such as: paper, plastic, mining, glass, transportation and many more.

In addition, the rbon brushes for electric motors, e essential for proper operation, because they give electrical connection between two parts which are: the fixed part and the rotor, which is the rotating part of a motor.

Types of carbon brushes

These are some types of carbon brushes that exist, for example:

  • Brushes for direct current motors.
  • Brushes for industrial machines
  • Brushes for ring brushes
  • Brushes for commutator maintenance equipment
  • Spring brushes
  • Coated brushes

Therefore, it is important to understand what electric motor brushes are for, since their purpose is to maintain the pressure that the motor needs to work so that energy, in this case electricity, can be transmitted.

What are the types of carbons for electric motors?

According to each need and industry, is the type of brush that is created. Therefore, it is important to know which is the right family of electric motor brushes.

  • Spring type brushes: is a resource widely used in motors that have a small size, are fractional or are used in small tools. The spring is the key part, since the contact comes from there.
  • Charcoal with cable: you can find them in different presentations such as one or four wires, they have different sizes... according to the needs. And they are a resource that can be used in many industries.
  • Biparted carbons: There are three types of them which are biparted carbons of one and two wires and multiflex or multi-pill carbons, which have two or more carbon pads, so that it has a good contact with the commutator and the action is completed quickly and efficiently.
  • Dumbbell type charcoals: they have a cable and at each end there is a carbon. There are four types of this carbon which are: single wire dumbbell carbons; two wire dumbbell carbons; riveted dumbbell carbons (can be single or double wire); and double dumbbell carbons.
  • Riveted coals: have a rivet on the front and back of the coal. There are four types of rivets: one-wire riveted coals; riveted coals for electric motors on the front and back of two wires; one-wire and two-wire biparted riveted coals.


Finally, it is important to understand that the rbon brushes a the key piece for the operation of any electric motor; since it depends on them that the energy is transmitted correctly. Therefore, they must be integrated with the highest quality standards for proper operation.
