Battery-powered screwdrivers are widely used in various fields, ranging from industrial assembly to medical applications, where precise torque delivery and user ergonomics are critical. One of the most influential components affecting the performance in this tool is the hammer mechanism, which stores rotational momentum and releases it as an impulsive torque during impact. This feature plays a crucial role in overcoming high static friction at the start of the screwing process. This study aims to mathematically model the integrated electromechanical and impact-induced dynamic behavior of a battery-powered screwdriver and to investigate the transient effects of the hammer mechanism through both theoretical and experimental approaches. In this context, a unified dynamic model incorporating the battery, DC motor, gear transmission, and hammer–anvil contact dynamics is developed using MATLAB/Simulink and validated against experimental data obtained from a custom-built test setup. The results demonstrate that the impulsive torque generated by the hammer mechanism significantly enhances screwing efficiency, particularly under high load conditions. The accuracy of the proposed model is quantitatively assessed using statistical error metrics, confirming its capability to capture the transient electromechanical interactions during impact events. Overall, this study provides a validated electromechanical modeling framework. The presented methodology offers a robust foundation for the design, analysis, and optimization of impact-driven power tools and may also serve as a reference for modeling rapid load transitions in applications requiring precise torque control, such as orthopedic and dental devices, robotic systems, and other mechatronic applications.
