Which components of the starter-generator require periodic inspection?

The commutator and brushes of the starter-generator are critical components that require periodic inspection due to their role in the electrical functioning and performance of the system. The commutator serves to reverse the current direction to maintain the rotational motion of the motor, while the brushes make contact with the commutator to transfer electrical current. Over time, wear and tear can occur due to friction, leading to potential issues such as poor electrical conductivity, overheating, or failure to start the engine effectively.

Regular inspection of these components helps ensure that any wear is identified early, allowing for maintenance or replacement before it results in significant operational problems. Proper care of the brushes and commutator helps maintain the efficiency and reliability of the starter-generator assembly and the overall engine performance.

The other components mentioned, such as the armature and the starter casing, while they may have maintenance protocols, do not require the same level of periodic inspection as the commutator and brushes, which are more susceptible to wear due to their direct interaction and mechanical function.
