Carbon brushes

Carbon brushes are key components of power tools, responsible for conducting electricity to the motor. They are essential for the proper operation of tools such as drills, grinders and hammers. When choosing brushes, it is important to match their size and material to the specific model of the device. When replacing carbon brushes, it is worth paying attention to their dimensions and technical specifications to ensure durable and efficient operation of the tool.

Carbon brushes are components that play a key role in the operation of many power tools and electric machines. They are used to transfer current from the stationary part of the motor (the stator) to the rotating part (the rotor), which allows the machine to be driven.

How do carbon brushes work?

  • Conduction of current - Carbon brushes transmit current from the stationary part of the motor to the rotor, allowing it to move.
  • Cooperation with the commutator - Brushes work with the commutator, which converts electrical energy into mechanical energy, driving the tool motor.

How to choose the right carbon brushes?

The selection of carbon brushes is crucial to the performance and life of power tools. It is important to pay attention to:

  • Dimensions - Brushes must be sized to fit the socket on the power tool. Even a minimal difference in dimensions can affect their performance.
  • If the brushes are too large, it is possible to grind them down with sandpaper.
  • Material - Depending on the intensity of use, you can choose graphite, copper-graphite or other mixtures of brushes that work best with a particular type of commutator.
  • Power tool model - Brushes must fit perfectly to ensure proper current conduction and long life of both brushes and motor.

Why is regular inspection of carbon brushes important?

Regular inspection and replacement of worn carbon brushes helps prevent motor failures and increases tool performance. An improper brush can cause excessive sparking and accelerated wear of the commutator, leading to costly repairs in the long run.

In summary, carbon brushes are an essential component of power tools, responsible for their smooth and reliable operation. Choosing the right brush - in terms of size, material and compatibility with the tool - is crucial for long and trouble-free operation.
