Why are debris and contaminants hazardous for motors?

Debris and contaminants are hazardous for motors primarily because they can cause overheating and electrical faults. When debris accumulates within the motor, it can obstruct airflow, impede necessary heat dissipation, and lead to overheating. This elevated temperature can damage the insulation of windings, potentially resulting in electrical faults such as short circuits. Additionally, contaminants can infiltrate the motor’s bearings and other moving parts, creating friction that further contributes to overheating and can cause mechanical failure. In summary, it is crucial to maintain motors free of debris and contaminants to ensure their optimal performance and longevity.
