Analysis of Inrush Current Loads in Electric Motors in Low Temperature Tests

This study examines the effects of inrush current loads on electric motors operating under low-temperature conditions. While electric motors have a wide range of applications in industrial and military environments, they face significant performance challenges in low-temperature settings. In particular, inrush current loads reduce the efficiency of the motor, leading to overheating, wear, and, ultimately, component failure in long-term use. In this study, the fluctuations in inrush current occurring under low-temperature conditions were evaluated. Experimental data reveal that when the motor operates in low temperature environments, current loads increase significantly, which, in turn, raises the motor's energy consumption. The focus is on the necessity of improvement strategies, particularly for electric motors used in harsh military applications. The research also explores strategies to manage inrush current loads at low temperatures. In conclusion, this study highlights the negative effects of inrush current loads experienced by electric motors under low-temperature conditions and suggests design and operational improvements for motors operating in such environments.
