How long do DC motor brushes last?

The life of a DC motor brush depends on several factors, such as the type of motor, its use and the operating conditions. In general, carbon brushes used in DC motors can last from a few thousand hours to tens of thousands of hours, depending on the operating conditions of the motor and the quality of the carbon brushes used.
The wear rate of motor brushes depends on the amount of current passing through the brushes, the speed of the motor, the type of load applied to the motor, and the cleanliness of the brushes and commutator. Brush wear usually accelerates when the motor is subjected to high loads or speeds, or when the brushes and commutator are not kept clean.
It is recommended that brushes be inspected regularly and replaced when necessary to ensure optimal performance of the DC motor. When maintaining and replacing brushes, follow the required steps.
