520			_aThis study focuses on the development of a small-scale wind turbine designed specifically for low wind speed areas, utilizing a dual-rotor axial flux generator. The primary objective is to create an efficient energy-generation system by combining magnetic levitation and advanced flux management techniques. The system employs magnetic bowls, where magnets repel each other and are tilted at seventy degrees to stabilize and lift the rotor, enabling frictionless operation. For the dual-rotor generator, a Halbach array configuration is used to enhance magnetic flux density, reduce flux leakage, and concentrate the magnetic field within the coils to maximize energy harnessing. The results demonstrate that magnetic levitation significantly increases the rotor's revolutions per minute compared to traditional bearing systems, while also reducing friction. Furthermore, the Halbach array configuration enhances the flux density by threefold and increases the effective height of the magnetic field, leading to improved power output. A wind assessment conducted at Cupang Senior High School in Muntinlupa City, near Laguna de Bay, confirmed the suitability of the site’s low-speed, onshore wind conditions for small-scale turbine deployment. CFD analysis using SimScale showed that the Conventional Savonius blade design outperformed the Ice blade design in terms of low- speed performance. FEA further verified the effectiveness of the Halbach array in enhancing magnetic field strength and generator performance, especially at smaller air gaps. These findings support the DAHAPMSG system’s viability as a reliable, efficient renewable energy solution for low-wind, urban environments.
