If a motor needs routine maintenance, what is a likely task related to its brushes?

Routine maintenance for electric motors often includes the care and replacement of brushes. Brushes are essential components in motors that facilitate the transfer of electrical energy to the rotating parts. Over time, brushes can wear down due to friction and excessive heat, leading to decreased performance and potential motor failure.

Replacing brushes is a standard practice because it helps maintain efficient operation and ensures good electrical contact between the brushes and the commutator. This task is straightforward and often part of preventive maintenance schedules. Ensuring that brushes are in good condition can significantly extend the life of the motor and optimize its performance.

Other tasks, while potentially important for different types of machinery or components, are not directly related to the upkeep of motor brushes. Calibrating voltage, changing oil, and adjusting speed pertain to various aspects of motor function or to other types of machinery maintenance but do not specifically address the wear and tear associated with brushes.
