In recent years, the efficient utilization of low-frequency mechanical energy sources has attracted considerableattention in renewable energy research and the development of self-powered systems [1][2]. One of the promisingmethods for converting ambient mechanical energy into electrical energy is electromagnetic energy harvesting based onlinear motion mechanisms [3][6]. However, traditional linear electromagnetic generators, which are typically designed withopen magnetic circuits or cylindrical cores, experience significant magnetic flux leakage, resulting in reduced conversionefficiency.In this study, a new linear electromagnetic energy harvesting module based on a slotted toroidal magnetic core structureis proposed. This design improves magnetic flux confinement and enhances overall induction efficiency. A detailedmathematical model of the system is developed by integrating magnetic circuit theory, principles of electromagneticinduction, and electrical load analysis. The magnetic flux distribution is represented as a function of the magnet’s position,while an analytical expression for the induced electromotive force (EMF) is derived by considering the relative motionbetween the magnet and the coil.In addition, the effects of key parameters such as air-gap length, number of coil turns, magnet velocity, and load resistanceon output voltage and generated power are thoroughly analyzed. The optimal conditions for maximum power transferare also determined analytically. The results indicate that the toroidal magnetic core configuration effectively minimizesmagnetic flux leakage and significantly improves energy conversion efficiency compared to conventional designs. Theproposed model provides a theoretical basis for the design and optimization of high-performance linear electromagneticenergy harvesting systems, particularly for low-frequency energy applications.
