What is the potential risk of operating a motor beyond its rated current?

Operating a motor beyond its rated current poses a significant risk of increased heat generation, which can lead to eventual motor failure. When a motor draws more current than its design specifications, the additional current results in higher power losses in the form of heat due to the increased resistance in the motor windings. This excessive heat can deteriorate insulation materials and other components within the motor, ultimately causing operational issues and potential failure.

Moreover, running at elevated current levels may also result in mechanical stress on the motor's components, leading to wear and tear that further shortens its lifespan. Regular operation at or beyond the rated current can significantly reduce the reliability and efficiency of the motor, emphasizing the importance of adhering to specified current ratings for optimal performance and durability.
