Function of carbon brush in micro DC motor


stay Micro DC motor There will be a pair of small brushes, which are installed in the back cover of the micro DC motor. Generally, they are carbon materials (carbon brushes) or metal materials (precious metal brushes). In brush DC motors, they are indispensable. So what is the role of carbon brushes in micro DC motors?


 Carbon brush of Micromotor


No matter the generator or the micro DC motor, there will be rotor and stator, and the rotor is excited to rotate. Therefore, one end of the rotor needs to be contacted and conductive with carbon brush, but the carbon brush will have friction, so the larger DC motor needs regular maintenance and replacement.


In fact, as a sliding contact, carbon brush is not only used in micro DC motor, but also in many electrical equipment. The shape of carbon brush is generally square, which is stuck on the metal support at the bottom of micro DC motor. The carbon brush is pressed on the rotating shaft with spring. When the micro DC motor is rotating, the electric energy is transmitted to the coil through the commutator.


 commutator


The main role of carbon brush is to change the direction of the current, through the commutator to make the micro DC motor non-stop rotation, carbon brush conductivity, thermal conductivity, lubricity are relatively good, and has a certain mechanical strength and commutation, in need of high speed, long life of micro DC motor, almost all carbon brush.


 Micro DC motor


As an important part of the electric motor, it is easy to lead in the direct current brush.
