What is the consequence of not maintaining breathers in sealed motor enclosures?

Maintaining breathers in sealed motor enclosures is critical for proper motor operation and longevity. When breathers are not maintained, the sealed environment that protects the internal components of the motor can become compromised.

Without adequate breathers, pressure differentials can occur when the motor operates or as temperatures change, which can lead to the ingress of dust, moisture, and other contaminants. This accumulation of foreign materials can damage internal components, lead to overheating, and ultimately increase the risk of failure. Proper breathers allow for ventilation while filtering out harmful particles, thus ensuring that the interior remains clean and that components are adequately lubricated and cooled.

This highlights the need for regular maintenance of these components to mitigate any risks associated with contamination, thereby maintaining the motor’s efficiency and reliability.
