Where are internal motor protection devices typically found?

Internal motor protection devices are typically found in or near the motor windings because these devices are designed to monitor the electrical characteristics and temperature of the motor during operation. Their primary function is to prevent overheating and damage to the motor by disconnecting power when abnormal conditions, such as excessive current or high temperatures, are detected. By placing these protection devices close to the windings, they can accurately sense the conditions that may lead to failure, ensuring the motor operates safely and efficiently.

This strategic placement allows for prompt and effective response to potential issues, safeguarding the motor and extending its service life. While other locations may host different components or controls associated with the HVAC/R system, internal motor protection devices serve a specific purpose directly related to the motor’s performance and safety.
