Carbon brushes need to be replaced regularly. Carbon brushes play an important role in the motor to transfer current and change the direction of the current, but they are also wearing parts. The degree of wear and tear of carbon brushes, the frequency of use of the motor, and the factors of the working environment will all affect the service life of carbon brushes. Under normal circumstances, if the carbon brush is used frequently, it needs to be replaced about once a year or so. However, the specific replacement cycle needs to be comprehensively considered according to various factors such as the hardness of the carbon brush itself, the overall quality of the motor, the smoothness of the copper head of the motor, the size of the load, the size of the current, and the environment in which it is used.
When replacing carbon brushes, there are certain steps that need to be followed, including removing the spring clip that needs to replace the carbon brush, loosening the brush braid fastening screws, removing the carbon brush braid and carbon brush, installing a new carbon brush and putting it back in the opposite direction, and checking that the generator carbon brush is working properly. At the same time, you also need to pay attention to some safety precautions when replacing carbon brushes, such as avoiding two people working at the same time, buttoning clothes and cuffs, standing on the insulating mat, avoiding touching both poles or one pole to the ground at the same time, ensuring that the same unit uses the same type of carbon brush, and paying attention to current and temperature parameters after replacement.
Therefore, in order to ensure the normal operation of the motor and prolong its service life, it is necessary to regularly check the wear and tear of the carbon brushes and replace them in time if necessary.
