Abstract : The growing demand for sustainable and decentralized energy solutions has led to increased interest in energy harvesting techniques within transportation systems. This paper presents the design and performance analysis of an optimized energy harvesting system based on train wheel rotation. Unlike conventional approaches, the proposed system focuses on improving energy conversion efficiency and output stability through optimized mechanical and electrical design. The system utilizes a gear-based transmission mechanism to enhance the rotational speed of the generator, enabling efficient energy conversion even at low wheel speeds. A regulated power conditioning circuit is incorporated to stabilize the output voltage and improve usability for low-power applications. Experimental evaluation is conducted using a prototype setup to analyze the relationship between rotational speed, voltage, current, and output power. The results demonstrate that the optimized system achieves improved power output and reduced voltage fluctuations compared to conventional directcoupled systems. The study highlights the importance of mechanical design optimization and efficient energy management in enhancing the performance of wheel-based energy harvesting systems. The proposed system is suitable for low-power railway applications such as sensor networks, signaling systems, and IoT-based monitoring devices. The findings contribute to the development of more efficient and practical energy harvesting solutions for railway infrastructure.
