What is one function of overload protection in electric motors?

One function of overload protection in electric motors is to prevent excessive current flow that can cause damage. Overload protection devices monitor the current levels within the motor. When the current exceeds designated levels, typically due to mechanical overload, a fault condition, or a start-up surge, the overload protection mechanism acts to interrupt the power supply. This intervention is crucial because sustained high current can lead to overheating, insulation breakdown, and ultimately motor failure. As a vital safety feature, overload protection helps to prolong the life of the motor and maintain its integrity during operation, ensuring that it functions reliably over time.
